Katalin's Take On What Makes the Perfect Cake Filling

The key to cake fillings is all about balance. A good filling (often more than one filling is used) should complement the flavor and texture of the cake without overpowering it. Whether it’s a rich, creamy buttercream or a tangy fruit curd, the key is in the quality of ingredients and the right consistency.

I often recommend using a less sweet, delicate filling, such as cream cheese frosting or fruit curd, between the cake layers. This allows the flavors to shine in every bite. For the outer frosting, I suggest opting for more stable, less delicate recipes (e.g., Swiss meringue buttercream) to ensure a smooth, sturdy finish that holds up throughout the cake’s presentation. This combination provides a balance of texture, flavor, and durability for a perfect cake experience.

My ultimate list of cake-filling ideas to transform your cakes

1. Peanut butter cream cheese frosting

This silky smooth peanut butter cream cheese frosting will put a delicious twist on your favorite desserts! In this easy five-step recipe, I eliminate the butter and cut back the sugar to create a creamy, delicious balance of sweetness and rich peanut butter flavor. In just five minutes, you’ll have a finger-licking topping that you can use for frosting peanut butter cakes, cupcakes, cookies, or even ice cream!

2. Raspberry Cream Cheese Frosting

Certainly, no one will be able to resist a cake filling like this. Rich and tangy cream cheese frosting is spiked with fresh raspberry puree to make the most delicious frosting. It works as well with chocolate as it does with vanilla, which is surely a bonus, too.

3. French Buttercream

Of all the different types of frosting, buttercreams are perhaps my favorite. They are so versatile and have this incredible texture. They take on flavor really well and, of course, have that buttery taste. French buttercream is super smooth and silky, with added richness from the egg yolks.

4. Swiss Meringue Buttercream

SMBC, as it is known in the culinary world, is one of the most common cake fillings and frostings. It is made by dissolving sugar into egg whites over gentle heat and then whipping it into a meringue before adding softened butter. The result is a silky, stable cake filling that everyone loves.

5. Strawberry Cream Cheese Frosting

Get the flavor of fresh strawberries into your cakes by making a cream cheese frosting with added berry goodness. This cake filling is suitable for piping and spreading, and it's perfectly balanced in sweetness.

6. Italian Meringue Buttercream

Whilst making Italian meringue is a bit more complicated due to the hot sugar syrup stage, it is well worth the extra effort! The silky, glossy appearance, soft and buttery texture, and extra stability are all divine. You can pipe it, color it, and flavor it, too.

7. Strawberry Buttercream Frosting

This creamy strawberry buttercream frosting is the delightful, fruity touch you've been looking for to top your favorite desserts! This easy recipe infuses my rich American buttercream with fresh strawberries, creating a smooth, fluffy, balanced frosting that will leave you licking your fingers. The best part is it only takes 10 minutes to make!

8. Oreo Frosting

Oreo lovers, you going to seriously like this one. It's a delicious, silky American buttercream frosting with crushed Oreo cookies. Perfectly pipeable yet full of Oreo flavor and a hint of crunch. What's more, it's well-balanced in sweetness, too.

9. Mango curd

Get a tropical taste by spreading your cake layers with homemade mango curd. Making curd is one of my favorite things, and the taste is unreal compared to store-bought versions. I'll give you all my top tips for smooth and creamy curd flavored with ripe and juicy mangoes.

10. Funfetti Frosting

Let's put the fun into cake filling ideas with a cute and crunchy funfetti frosting. You can choose the type of sprinkles you put into the cake filling to match a theme, too. In conclusion, I love using this cake filling on layer cakes or cupcakes, or just enjoy it with a spoon!

11. Chocolate Buttercream Frosting

This is the smoothest, silkiest chocolate buttercream cake filling that no one can ever get enough of! It is packed with chocolate flavor, stable enough to pipe, and not too sweet, either. Surely, cake filling ideas don't come any better than this.

12. Coconut Frosting

This cake filling is a type of ermine frosting that seems unusual, but trust me, the texture and taste are off the charts! It's a boiled milk frosting made with a flour paste, but all you can taste is creamy goodness. In this version, I flavor it with coconut so you get this incredible cake filling you can use with anything from chocolate to tropical fruits and berries.

13. Coffee Buttercream Frosting

Who else likes a hit of caffeine with their cake? Moreover, coffee helps to bring out the taste of chocolate, so this buttercream cake filling is perfect with chocolate cakes and cupcakes.

14. Raspberry Buttercream Frosting

Undoubtedly, this has become one of my favorite cake fillings. Spread onto sponge cake layers, it adds a hit of raspberry flavor with each bite. It's tangy and certainly just sweet enough, with that beautiful pink cake filling color.

15. White Chocolate Frosting

No one can resist this white chocolate cake filling. Certainly, I've never met anyone who can stop eating it! White chocolate desserts can sometimes be very sweet, but I ensure this is perfectly balanced and super easy to make.

16. Chocolate Whipped Cream Frosting

You will love my chocolate version if you like a classic chantilly cream cake filling. It's light and airy, super fluffy, and delicately sweet. Try it with all the different cake flavors you love, and you won't be disappointed.

17. Lemon Buttercream Frosting

A hit of citrus tang through a sweet cake filling is always a winner in my book. Sometimes adding lemon to buttercreams can be tricky, but I give you all my pro tips on how to avoid splitting or curdling. I especially love spreading cakes with this filling and some fresh raspberries. Delicious!

18. German buttercream

Easy German Buttercream (or crème mousseline) is my favorite buttercream frosting. Basically, it's a simple pastry cream enriched with butter, so it is a bit more complex to make, but it isn't as sweet as American buttercream. It's super smooth and silky and the best cake filling for a variety of desserts, from layer cakes (this is probably one of the best cake filling ideas for vanilla cake) and cupcakes to French macarons.

19. Whipped chocolate ganache frosting

Who can resist a decadent whipped chocolate ganache frosting slathered on a chocolate layer cake? Not me. Undoubtedly, this smooth and silky whipped chocolate ganache is one of the original and best cake fillings around. Ganache frosting is also very easy to make, even for beginner bakers.

20. Lemon curd

You can use lemon curd in so many desserts, and making it from scratch is a valuable kitchen tool to have. It makes the most deliciously tangy coconut cake filling or works perfectly with vanilla, and it also cuts through chocolate in a delicious way. Not to mention using it as a filling for lemon poppy seed cupcakes!

21. Mascarpone frosting

This silky mascarpone frosting is the perfect frosting for your cakes and cupcakes. It pipes beautifully and does not contain a lot of added sugar like some other caking fillings and frostings. You can make this delicious, velvety-smooth cake frosting using three simple ingredients; it takes less than five minutes. This is one of my favorite cake filling ideas for vanilla cake.

22. Caramel filling

Try this homemade caramel filling for cupcakes, cakes, tartlets, brownies, pies, or any other desserts! It is so buttery and silky with balanced sweetness, plus it won't go hard.  Even beginner bakers can make homemade caramel cake filling; it takes 5 minutes and has just four simple ingredients. Caramel filling tastes especially delicious with apples and Fall flavors, but I enjoy it at any time of year as these chocolate caramel cupcakes for example.

23. Nutella frosting

Rich chocolate cake with Nutella frosting has to be one of the most popular birthday cake flavors and fillings. Because who doesn't love the rich and smooth chocolate hazelnut spread? The nutty flavor tames the sweetness slightly, but overall this is a super decadent cake filling for serious chocoholics only. Make sure to try these Nutella cupcakes and Nutella cake.

24. Frangipane

Frangipane is used as the filling in French Kings Cake (Galette des Rois), baked between two layers of buttery puff pastry, and I can safely say that it makes the best pastry filling. Creamy, nutty, and easy to make, what's not to love? Frangipane pairs well with chocolate but also with fruits like apples and pears.

25. Crème pâtissière

A crème pâtissière or vanilla custard cake filling is one of the classics used in so many French pastries. It is a rich and thick custard made from milk, eggs, and starch, and it's well worth learning how to make it! A cake layered with pastry cream will be a real showstopper.

26. Namelaka

Chocolate namelaka is the most delicious cream that you can use to fill, frost, or beautifully decorate your desserts. Its texture is the perfect mix of ganache, pastry cream, and mousse, making it rich, silky, delicate, and light. Please note that you can make namelaka with dark chocolate, milk chocolate, or white chocolate too, so it is super versatile.

27. Homemade Lotus Biscoff spread

Fill cakes or cupcakes with this homemade Lotus Biscoff spread, it is super easy, and you can make it in under 10 minutes! Biscoff spread is my favorite filling for vanilla cake as it lets the Biscoff flavor sing, or you can use it in tons of other Biscoff recipes.

28. Diplomat cream

Diplomat cream or crème diplomate has a unique taste and texture. In comparison with pastry cream, it is lighter. Yet, it is richer than simple whipped cream filling. Therefore, there are numerous diplomat cream uses. It works well in a tart; it's a delicious cake filling, a classic eclair filling, or even makes a tasty small dessert dish on its own.

29. Chocolate cremeux

Chocolate cremeux has to be one of the best cake fillings and frostings. Crémeux au chocolat is made with five simple ingredients and has a silky texture that isn't too firm and isn't too soft. Overall, chocolate crémeux is simply the perfect creamy topping or filling for your favorite pastries, tarts and cakes like this Triple chocolate cake.

30. Cream cheese frosting

Make this delicious, velvety-smooth, easy-to-pipe cream cheese cake filling in less than 3 minutes! Surely, cream cheese frosting is the most perfect flavor combination for red velvet cake or spread onto brownies.

31. Caramelized apple topping

A caramelized apple topping has to be one of the easiest and most delicious ways to fill a cake. It's so versatile and full of warm, comforting flavors that go wonderfully with baked goods but also with pancakes, waffles, crepes, and ice cream. It's the perfect cake filling for Fall.

32. Homemade Nutella

Crazy delicious and smooth with a deep nutty flavor - I use this homemade Nutella on everything! It is sophisticated and sweet but very well-balanced, which makes it the ideal cake filling. Nutella is a delicious cake filling flavor combination for strawberries, raspberries, or banana.

33. Strawberry compote

Strawberry compote is a classic summer cake filling and one of my all-time favorite fillings for layer cakes like Victoria sponge. It has such a fresh fruity flavor, and what's more, it is a lot easier to make than you'd think!

34. Whipped cream

Whipped cream or Chantilly has to be the most versatile cake filling as it tastes delicious on its own, but it can also be flavored with citrus zest or even desiccated coconut to make coconut cream. Or it can be paired with other frostings like a strawberry compote or homemade Nutella. Whipped cream is also one of the best decoration elements or fillings for chocolate cake layers.

35. Russian buttercream

If you find my American buttercream recipe too thick and sweet, my delicious vanilla Russian buttercream is here to save the day! Made with just two basic household ingredients, this flavorful, fluffy, condensed milk frosting is the perfect substitute for topping and filling your favorite cakes, cupcakes, and cookies!

36. Biscoff buttercream

Biscoff-flavored German buttercream frosting? Undoubtedly, this might be the most delicious frosting that you will ever make! Mousseline cream is a pastry cream-based frosting which means it is enriched with butter as well as Biscoff spread. Rich caramel flavors mixed with creamy butter, it is absolutely out of this world.

37. Hazelnut frosting

Try this luxuriously silky hazelnut mousseline cream for the most amazingly decadent cake filling. It is enriched with hazelnut praline paste for the most incredibly nutty flavor. In fact, hazelnut works very well with chocolate and coffee, and hazelnut and raspberry are another one of the best cake filling combinations.

38. Pistachio ganache

Pistachio ganache is so full of pistachio flavor and much less sweet than a buttercream frosting. Making a pistachio ganache cake filling means you get nutty flavor and richness from white chocolate and heavy cream, but the lower sweetness perfectly balances your cake. Moreover, pistachio ganache is one of my personal favorites for filling macarons.

39. Raspberry ganache

You have to make this delicious raspberry ganache; it is the best raspberry cake filling. Tangy and sweet raspberries are blended and mixed with whipping cream and white chocolate, which perfectly takes on their flavor. But in addition, the texture is super silky and rich. You can use raspberry ganache for tarts, layer cakes, or as macaron or cupcake filling.

40. 7-minute frosting

This easy 7-minute frosting is the perfect solution when you’re short on time and need a quick yet delicious topping for your favorite desserts! Using only egg whites and sugar as its two main ingredients, this old-fashioned frosting recipe has a light flavor and a fluffy, creamy texture that will take your pies, cakes, and cupcakes to the next level!

41. Pistachio buttercream

French buttercream is made with sugar syrup, egg yolks, butter, and pistachio paste, so it can be more complex to make, but the results are well worth it. It is silky smooth and luxurious! It’s subtly sweet, ultra-creamy, and works well as a vanilla sponge cake filling.

42. Lemon sweetened condensed milk buttercream

Lemon condensed milk frosting is rich, fluffy, and bright, the perfect cake filling combination. It has a distinctive but delicate lemon flavor, and the addition of sweetened condensed milk adds an amazing quality that is hard to describe! Evidently, this needs to be tasted to be believed.

43. Coffee pastry cream

Coffee lovers will adore this coffee-infused pastry cream. It's the perfect choice if you're searching for vanilla cake fillings, chocolate cake filling ideas, or even banana cake flavor combinations. This coffee cake filling also works well with chopped walnuts, which also means added crunchy texture.

44. Salted caramel Swiss meringue buttercream

Salted caramel anything is surely a winner in my book, and I feel like it would work with pretty much any cake recipe. First, make your own homemade salted caramel sauce. After that, make your Swiss meringue. And finally, whisk in butter. The result, is more refined than American buttercream, a little less sweet, and incredibly light and fluffy!

45. Cherry frosting

Pipe cherry frosting on chocolate cake and create a Black Forest gateau vibe! Or, it works equally well if you're looking for light and fruity vanilla cake filling ideas. This is a super easy cake filling for Spring or Summer that you can combine with other flavors in delicious and interesting ways.

46. Orange curd

This easy orange curd recipe makes a delicious filling for cakes, spread for scones, in a fruit tart, or even as a topping for cheesecake. Creamy orange curd is easy to make at home and is a softer citrus curd to lemon or lime, with less bite or tartness.
