Want a chocolate buttercream that’s light and fluffy?

For a light and fluffy frosting try whipping up a batch of Swiss or Italian meringue buttercream. Both use whipped egg whites to create a light and fluffy frosting. Mix in 1/2 cup of melted and cooled dark chocolate and a teaspoon of espresso powder for an amazing fluffy chocolate icing.

Pro Tips For Making Rocky Road Cupcakes

  • I love using a high-quality Dutch processed cocoa powder. Dutch processed cocoa powder is darker, less acidic and fudgier in baked goods.
  • You can use room temperature or even cold coffee in the batter if you’d prefer.
  • Not a coffee fan? Sub in water or milk instead.
  • For a lighter cupcake try whipping up a batch of Italian meringue! for the frosting. You can toast it then sprinkle with chunks of chocolate and toasted nuts!
  • You can make your own marshmallow fluff with ease! Use the recipe from my marshmallow brownie. You may want to halve it as it makes a lot.
