Dark Chocolate Peanut Butter Cupcakes Recipe Tips:

  • Use high quality cocoa powder . When you make chocolate desserts, as you want the chocolate to shine. You can use regular unsweetened cocoa, or Special Dark Unsweetened Cocoa. I have used the latest to achieve the dark chocolate flavor in these Dark Chocolate Peanut Butter Cupcakes.
  • Don’t skip the salt as the salt will enhance the chocolate flavor.
  • Ingredients should be at room temperature for that perfect airy, soft and moist crumb.
  • Use creamy peanut butter in this recipe.
  • Make sure you don’t over bake the cupcakes, each oven is different but checking at the 15 minute mark is key.
  • Use quality dairy products as they will make a huge difference in this recipe, especially in the buttercream.

Buttercream also know as butter icing is a type of icing or filling used inside cakes and cupcakes, as a coating, and as decoration. It is very easy to make, by creaming butter with powdered sugar, although other fats can be used, such as margarine or lard.

  • In a large mixing bowl or in the bowl of an electric mixer fitted with the whisk attachment, combine peanut butter, oil, and brown sugar, beat until all combined and fluffy.
  • Add in the eggs one at a time, and vanilla extract. Beat on medium speed until combined. Stop a few times to scrape the sides and bottom of the bowl with a spatula.
  • Add the flour mixture and buttermilk, alternating between the two and mixing by hand (to avoid over mixing) until all combined.
  • Fill the cupcake liners almost completely full with batter.
  • Bake for 15-17 minutes or until a toothpick inserted in the center comes out with just a few crumbs.
