Directions
- Chocolate Cake
-
Preheat your oven to 350 degrees and prepare your cupcake pan with liners.
-
Sift your flour, cocoa, baking soda and baking powder into a large bowl. Add your sugar and salt - whisk until combined. Set aside.
-
Measure out your buttermilk, coffee, melted butter, eggs and vanilla and add to dry ingredients. Whisk for 1-2 minutes until there are no lumps.
-
Fill your cupcake liners 2/3 high with batter and bake for 10 - 12 minutes until they bounce back when touched OR when a toothpick comes out clean. Let them cool, or if you're impatient like I am, put them in the freezer for a few minutes.
- Peanut Butter Swiss Buttercream
-
Add your egg white and sugar to a very clean bowl over a double boiler. Whisk them until the sugar is completely dissolved and the mixture is quite hot.
-
Using a stand mixer, clean the bowl with a few drops of lemon and wipe dry with a clean, new cloth. Whip the hot sugar and whites into a fluffy meringue for as long as it takes until the meringue is room temperature, not hot.
-
While still whisking, slowly add your room temperature butter one cube at a time until it's thoroughly incorporated. Add your vanilla and salt. Follow with your peanut butter, tasting inbetween additions. You can really add as much or as little as you like.
-
Pipe or use an offset to decorate your cupcakes. Make sure the cupcakes are completely cooled or the icing will slide off - disastrous!
