I love baking as is demonstrated by the many desserts found in the recipe index.

How to Make the BEST Double Chocolate Cupcakes with Peanut Buttercream Icing

  • Ingredients you’ll need to make homemade Double Chocolate Cupcakes: One box Devils Food cake mix, buttermilk, large eggs, butter and semi sweet chocolate baking chips.
  • To make the Peanut Buttercream Icing you’ll need: Peanut butter, powdered sugar, heavy cream, softened butter, vanilla extract and chopped peanuts for garnishing.
  • Kitchen tools you’ll need: Two 12 cup muffin/cupcake pans, cupcake liners, hand mixer or stand mixer, measuring cups and spoons, sharp knife and chopping board or nut chopper to chop the peanuts, icing spatula or pastry bag fitted with a jumbo open star tip.
  • When making these cupcakes, you can use a doctored cake mix as demonstrated in the recipe or you may opt to use my Double Chocolate Cake recipe for the batter if you prefer to bake from scratch.
  • The cupcakes can be made one day in advance then frosted just before serving. Especially if it’s your plan to drizzle with warm ganache.
  • Should you like to make the frosting in advance. Chill it in an airtight container then bring to room temperature to soften and whip with a whisk or a mixer  before frosting the cupcakes. Have extra cream on hand to thin, if needed.
  • Store frosted Double Chocolate Cupcakes in an airtight container chilled in the refrigerator for up to 4 days.
