Chocolate Cupcakes with Chocolate Buttercream Frosting
My favorite chocolate cupcakes! These are soft, fluffy, moist and perfectly sweet, rich and chocolatey. So good that they might even become the special birthday request every year! A chocolate lovers dream.
In large heat proof mixing bowl, whisk together cocoa powder and baking soda. Carefully pour in boiling water and whisk until bubbling subsides and mixture is well blended, allow to cool for 5 minutes.
Meanwhile, in a separate large mixing bowl, using an electric hand mixer set on low speed, blend together melted butter, vegetable oil, granulated sugar, vanilla and salt until well combined, about 30 seconds.
Mix in egg then eggs yolk. Blend in lukewarm cocoa mixture then blend in heavy cream. Add flour and blend until well combined, while scraping down sides and bottom of bowl.
Divide batter among 12 paper lined muffin cups filling each about 2/3 full.
Bake in preheated oven until toothpick inserted into center comes out clean, about 17 - 20 minutes.
Remove from oven and allow to cool in muffin pan several minutes before transferring to wire rack to cool. Cool completely then frost with chocolate buttercream frosting.
For the chocolate buttercream frosting:
In the bowl of an electric stand mixer fitted with the paddle attachment cream butter until fluffy.
Mix in powdered sugar, cocoa powder, 2 Tbsp cream and the vanilla. Mix until light and fluffy while adding more cream to thin if needed.
Notes
*If you want the frosting even more chocolatey you can add another 2 Tbsp cocoa powder.
