Best Lemon Poppy Seed Muffins Recipe
These easy lemon poppy seed muffins take my classic lemon muffin recipe to the next level by adding crunchy poppy seeds for a mild, nutty twist. Unlike other muffin recipes, there’s no need for sour cream or Greek yogurt here. Thanks to a simple baking hack (more on that below), these muffins are naturally and wonderfully moist and fluffy.
This recipe is super easy to make, without fancy ingredients or special equipment. Chances are, you already have everything you need in your pantry. The high-quality ingredients give these muffins the freshest lemony taste, and the optional glaze kicks the flavor up even more!
The versatility of this recipe makes it even better. Whether you want to switch up the base flavor, add a filling, or try different toppings, you can make them uniquely yours. Let’s get started!
Katalin's Take On How To Make Muffins Super Moist
As I often mention, baking is a science where precision is key, and each element plays a crucial role. This is no exception when creating bakery-style lemon poppy seed muffins! Obtaining a tender, fluffy texture involves a combination of quality ingredients, precise measurements, and expert techniques.
First and foremost, you want to start with the right ingredients. I use both oil and butter in my muffin recipes, providing the perfect balance, richness, and flavor while ensuring the muffins remain moist. The proper ratio of wet to dry ingredients is equally important, so using a digital scale to measure is essential.
I like to use a signature trick to achieve exceptional fluffiness. By folding a mixture of vinegar and baking soda into the batter just before baking, it creates a light, airy texture without affecting the flavor of the muffins.
It’s also important to avoid overbaking. Baking for just the right amount of time at the correct temperature prevents dryness and ensures the muffins stay soft and moist.
Lastly, proper storage is crucial for keeping muffins moist and fresh. Placing them in an airtight container or following the storage tips provided in this recipe can extend their deliciousness for days!
The muffin batter comes together easily, however, pay attention to the ingredient temperatures
Before starting lemon poppy seed muffin batter, the first step is to ensure that your egg, milk, and butter are at room temperature so that they emulsify correctly. To quickly bring your egg to room temperature, stick it in a bowl of warm water for 5-10 minutes. See my guide on softening butter for tips on quickly bringing your butter to room temperature without using a microwave.
Finely zest the lemons into a small mixing bowl using a microplane grater then massage the lemon zest into the granulated sugar for a minute. This will enhance the lemon flavor on your muffins.
In a large bowl, use an electric hand mixer to cream the room-temperature butter and lemony granulated sugar until light and fluffy (see my guide on creaming butter and sugar for more tips on doing so flawlessly!).
Next, gradually add the eggs one at a time, mixing well between each addition. Lastly, mix in the vanilla extract and lemon zest.
Slowly pour in the oil while mixing continuously, followed by the room-temperature milk. Keep whipping the mixture until fully incorporated.
Sift, then whisk together the flour, baking powder, and salt. Do not skip the salt! It’s essential to balance the flavors. Using a rubber spatula, gently fold the dry ingredients into the wet mixture just until combined. Then, fold in the poppy seeds (or chia seeds, if preferred), taking care not to overmix.
In a separate small bowl, mix the vinegar and baking soda. It should bubble vigorously once combined. Immediately fold this mixture into the batter just until combined.
Using a piping bag or spoon, evenly divide the batter among the muffin liners, filling each about three-quarters full.
Bake and glaze the muffins
Bake the muffins for 20-22 minutes or until a toothpick inserted into the center comes out clean. Be careful not to overbake, as it can dry out the muffins. Allow the muffins to cool completely to room temperature before adding the glaze.
To make the lemon glaze, first, sift the powdered sugar to remove any clumps. Then, whisk together powdered sugar and lemon juice in a small bowl until smooth. Drizzle the glaze over the cooled muffins using a teaspoon or piping bag. Garnish with lemon zest and additional poppy seeds for a beautiful finishing touch!
What to do with leftovers
Lemon and poppyseed muffins have the best flavor and texture when you serve them the same day you bake them. However, if there are leftovers, store them in an airtight container at room temperature for up to three days. Once cooled completely, you can refrigerate them for up to a week.
To freeze, first ensure they have cooled completely to room temperature, then individually wrap each in plastic wrap followed by aluminum foil. Place the wrapped muffins in a sealed plastic freezer bag and store them in the freezer for up to three months. Thaw at room temperature.
For more tips, check out my guide on storing muffins to maintain their freshness.
Try some flavor variations
Swap the lemon zest for orange zest to create a citrusy twist. You can also try this recipe with Meyer lemons for a unique flavor twist!
Add fresh blueberries to the batter (as I do with my mini blueberry muffins) to make blueberry lemon poppyseed muffins (an incredible flavor combination). Or, experiment with other fruits like I do in my raspberry muffin, strawberry muffin, and banana mini muffin recipes.
Warm up the flavor by adding a pinch of cinnamon, allspice, cardamom, or apple pie spice to the batter.
Add a fruity surprise to the center by filling it with my homemade lemon curd, mango curd, or strawberry compote, as I do in my lemon poppy seed cupcake recipe (which you can also use to make a lemon poppy seed cake)!
Instead of a vanilla muffin base, you can try this recipe with chocolate as a base, as I do in my double chocolate chip muffins as a base.
Instead of the lemon glaze, top your muffins with decorating sugar, streusel crumbs, or sea salt. You can also make a blueberry or raspberry glaze instead, as I do in my blueberry donut and raspberry donut recipes.
Notes on Ingredient Substitutions
When making lemon poppy seed muffins, you may need a few simple ingredient substitutions to accommodate dietary needs, personal preferences, or forgotten items at the grocery store. However, before making substitutions, it is important to remember that even the most minor changes may require reformulating the other ingredients and will slightly affect the flavor and texture.
Consider using one of these many egg substitutes to make your lemon poppyseed muffins vegan. To make gluten free lemon poppyseed muffins, replace the all-purpose flour with a gluten-free blend. You can also refer to my flour guide for more alternatives.
If you prefer not to use lemon zest, try one of these suitable lemon zest substitutes to maintain the lemon flavor and aroma. However, I do not recommend using lemon juice or lemon extract, as juice can break the batter, and the extract can be too overpowering.
Expert Tips For Making Lemon Poppy Seed Muffins
- Opt for high-quality, high-fat ingredients for the best flavor. I like to use 3% whole milk and 82% fat European-style unsalted butter (using salted butter will make your muffins salty).
- Stick to the equipment specified in the recipe (i.e., rubber spatula vs. electric mixer) to avoid overmixing.
- Do not attempt to make the baking soda and vinegar in advance. Letting it sit will reduce its bubbly reaction, affecting how well the muffins rise.
- Use a small cookie scoop or piping bag for clean, even portioning of the batter into the muffin tin.
- To adjust the glaze consistency, add powdered sugar one tablespoon at a time for a thicker glaze or lemon juice one tablespoon at a time for a thinner glaze.
What Equipment To Use
Always use a digital scale to measure your ingredients accurately for the best and most consistent baking results. A digital oven thermometer can help ensure your muffins bake at the correct temperature, as oven settings can sometimes be slightly off, depending on the model.
An electric hand mixer is essential for whipping the sugar and wet ingredients together, but you will need a rubber spatula to gently fold the wet and dry ingredients without overmixing.
Once the batter is ready, you’ll need a 12-cup muffin pan to bake the muffins.
