Made with moist chocolate cupcake sponges, rich pecan coconut frosting, and decadent chocolate buttercream frosting, these handheld versions of the classic cake are an irresistible treat for any occasion!
Prepare your cupcake tin by lining it with muffin liners and preheat your oven to 175℃ / 350℉ (no fan).
With an electric hand mixer, whip together the wet ingredients for 1-2 minutes: room temperature egg, oil, sugar, coffee, milk, and vanilla extract.
Sift dry ingredients together; flour, baking powder, baking soda, cocoa powder, salt then pour the wet ingredients into dry ingredients and fold just until combined.
Spoon the batter evenly into the cavities of your cupcake tin, filling each one about ¾ full.
Bake the chocolate cupcake for about 20-22 minutes or until a toothpick inserted into the center comes out clean. Do not overbake them, as they can dry out.
Cool the baked cupcakes on a cooling rack. They must be at room temperature before frosting.
Chocolate buttercream frosting
Cream the room-temperature butter at medium-high speed for 3 minutes until it becomes light in color and fluffy in texture.
Add in the powdered sugar tablespoon by tablespoon at low speed, then turn the mixer back on medium-high speed and whip it for another 4 minutes or until the mixture becomes light, fluffy, and increases in volume.
Then, add the cocoa powder and whip it for another minute. Lastly, add the vanilla extract, salt, and heavy cream and continue whipping for another minute until it is smooth and silky.
This chocolate buttercream frosting should have the perfect pipeable fluffy texture. If, for some reason, it is too thick, add some more cream (1 tablespoon at a time). If the frosting is too thin, add more powdered sugar (1 tablespoon at a time).
Note that the buttercream texture is best straight after making it when the butter is at the right temperature (room temperature), and the mixture is freshly whipped. I like to use the frosting immediately or store it at room temperature in a piping bag for a few hours. If stored in the refrigerator, you will need to bring it back to room temperature before using it and might need to give it another minute or two to whip in the stand mixer to increase the volume again.
Pecan coconut frosting
The frosting is enough to decorate the tops of the cupcakes and also to fill them. If you do not wish to fill the cupcakes, reduce the ingredients by about 30%.
Cook all ingredients (except pecan and coconut) in a saucepan over medium heat until slightly thickens - stirring constantly while cooking to avoid egg yolk curdling. The process will take about 5-10 minutes. Pay attention to the consistency and remove the cream from the stove as soon as it thickens.
Let the cream cool to room temperature. Fold the shredded coconut and toasted chopped pecans in and let it rest in the fridge for 30 minutes to set.
Please note that this frosting is not pipeable like the chocolate buttercream, however, once chilled, you will be able to top the cupcakes with the frosting by simply using a small spoon.
Assemble
Move the chocolate buttercream frosting into a piping bag fitted with a piping nozzle. Decorate the cupcakes first with the pecan coconut frosting (using a spoon), then pipe the chocolate buttercream on top. Finish with finely chopped pecans.
The cupcakes are best served fresh. Any leftovers can be stored refrigerated for 2-3 days in an airtight container.
Notes
You might be able to make more or less cupcakes with this recipe, depending on the size of the cupcake tin cavities.Ingredient notes:
Measure your ingredients with a digital scale for accuracy.
All cupcake ingredients must be at room temperature to properly emulsify: eggs, coffee, and milk.
Use high fat (36%) heavy cream and good quality high fat (82%) butter for making buttercream.
Use dark, unsweetened cocoa powder, ideally Dutch-processed.
You can substitute the evaporated milk with 50% whole milk-50% heavy cream.
Technique notes:
Make sure you read my Expert Tips section above to maximize your success. A short recipe alone cannot cover all the necessary details and science behind baking.
A digital scale is required for a consistent, happy baking experience.
The cupcake batter will be very liquid; don't worry about it. Do not add more flour to it.
Always preheat your oven and consider using a digital oven thermometer for the best results.
Baking these cupcakes takes 22 minutes in my oven. However, you should focus on the texture, not the time. Apply the toothpick test (it should come out clean) to avoid overbaked cupcakes. Do not overbake them, as that will result in a dry texture.
The temperature and texture of the butter are key when making buttercream. Wait until it is soft, however, avoid last-minute microwaving.
When adding the powdered sugar and the cocoa powder, reduce the speed of the mixer to avoid creating a huge powder sugar or cocoa powder cloud.
I recommend the paddle attachment to avoid unnecessary air bubbles. To get your buttercream fully silky, without air bubbles, mix the cream at the end by hand with a rubber spatula for a few minutes.
