So here they are! But I made them without filling and some with strawberry topping for Mum, cause she can't eat peanuts.
Chocolate Cupcakes with Peanut Butter (Source: adapted from Annie Eats)
For the cake:
1 2/3 cups all-purpose flour
¾ cup unsweetened cocoa powder
1 tsp. baking soda
½ tsp. salt
1 cup sour cream
2 tbsp. milk
1 tsp. vanilla extract
8 tbsp. unsalted butter, at room temperature
1½ cups sugar
2 large eggs
For the frosting:
8 oz. cream cheese, at room temperature
4 tbsp. unsalted butter, softened
½ cup creamy peanut butter
3¼ cups confectioners’ sugar
1 cup frozen whipped topping, thawed
Preheat the oven to 350° F. Line two cupcake pans with paper liners.
To make the cake batter, combine the flour, cocoa powder, baking soda and salt in a medium bowl; whisk together and set aside. In a liquid measuring cup, stir together the sour cream, milk and vanilla extract. In the bowl of an electric mixer fitted with the paddle attachment, combine the butter and sugar, and beat on medium-high speed until light and fluffy, about 2 minutes. Beat in the eggs one at a time, scraping down the bowl as needed. With the mixer on low speed, alternately add the dry ingredients and the sour cream mixture, beginning and ending with the dry ingredients. Mix just until incorporated.
Spoon the batter into the cupcake liner till all the cups are filled. Bake for 18-22 minutes, or until a toothpick inserted in the center comes out clean. Allow to cool in the pan for 5-10 minutes, then transfer to a wire rack to cool completely.
To make the frosting, in the bowl of an electric mixer fitted with the paddle attachment, combine the cream cheese, butter and peanut butter until smooth. Slowly mix in the confectioners’ sugar, beating until smooth and well blended. Mix in the whipped topping until smooth and fluffy. Frost cooled cupcakes as desired.
