Directions
CUPCAKES
Preheat the oven to 350 degrees F (175 degrees C).. Line 24 muffin cups with paper liners.
Combine flour, cream of tartar, baking soda, and salt in a bowl.
In a large bowl, beat brown sugar, peanut butter, and shortening until light and fluffy. Beat in eggs, one at a time, then stir in vanilla.
Stir in dry ingredients alternately with milk.
Spoon into the prepared muffin cups, filling each cup.
Bake in the preheated oven until the tops spring back when lightly pressed, 15 to 20 minutes. Cool in the pan for at least 10 minutes before removing to a wire rack to cool completely.
BUTTERCREAM
Beat mashed banana, salt, and softened butter in a mixer until creamy (about 1 minute).
Add vanilla and cream of tartar.
Slowly beat in powdered sugar, and cocoa powder, 1 cup at a time, until smooth. Add more icing sugar if buttercream needs to be thicker.
Makes 24-30 cupcakes.
