Peanut Butter Cupcakes with Chocolate Ganache and Peanut Butter Buttercream
Cupcakes adapted from Sweet and Savory Tooth (who adapted it from Cupcakes! by Elinor Klivans)
Peanut Butter Buttercream adapted from Fifteen Spatulas
Yields 12 cupcakes
For the cupcakes
Ingredients:
1 cup all-purpose flour
1 teaspoon baking powder
1/4 teaspoon salt
6 tablespoons unsalted butter, at room temperature
3/4 cup chunky or smooth peanut butter
1 cup packed brown sugar
1 egg
1 1/2 teaspoons vanilla
1/2 cup milk (I used 2% milk)
Method:
Heat the oven to 350 degrees. Line 12 muffin tin cups with paper cupcake liners.
Sift the flour, baking powder and salt in a medium bowl and set aside.
Using a stand mixer, beat the butter, peanut butter and brown sugar, on medium speed, until smooth and ligh in color, about 1 minute. Stop and scrape the sides of the bowl, as needed. Mix in the egg. Add the vanilla and beat for 1 minute, or until the batter is smooth. On low speed, add the flour mixture in 3 additions and the milk in 2 additions, beginning and ending with the flour mixture and mixing just until the flour is incorporated and the batter looks smooth.
Fill each paper liner with batter, about 1/3 inch below the top of the liner. Bake just until the tops feel firm and are lightly browned, about 20 minutes. There will be a few cracks on top. Cool the cupcakes for 10 minutes in the pan on a wire rack. Carefully remove cupcakes from pan to finish cooling.
For the Ganache
Ingredients:
2 ounces bittersweet chocolate, chopped
1/2 teaspoon instant coffee granules
2 ounces heavy cream
Method:
Place the chocolate and coffee granules in a heatproof bowl. Heat the cream in a small sauce pan over medium heat, until it comes to a boil. Pour the hot cream into the bowl with the chocolate and stir until completely mixed and glossy.
For the Peanut Butter Buttercream
Ingredients:
1 cup unsalted butter, at room temperature (2 sticks)
1 cup powdered sugar, or more, to taste
1/8 teaspoon salt
1/2 teaspoon vanilla extract
3/4 cup peanut butter, at room temperature
Method:
Beat everything in a bowl until smooth and blended. Add in more powdered sugar, if needed, according to your preference.
Assembly
Spread a layer of chocolate ganache on top of the cupcake and then frost with the peanut butter buttercream.
