Light and fluffy chocolate cake with clouds of creamy peanut butter frosting – who’s with me? 🙋‍♀️

I’ll be honest with you. I actually developed this particular recipe back in 2015. But four years on, it still holds the test of time. These are by far, my favourite Peanut Butter Chocolate Cupcakes. There is just something about the combination of creamy peanut butter frosting and soft chocolate cake that makes me weak at the knees.

You’ll love that they’re surprisingly quick and easy to make, with no special ingredients. But they really do wow a crowd. Especially with a little extra drizzle of peanut butter and a few chocolate chips for good measure. You know how we roll around here #moreismore

HOW TO MAKE CHOCOLATE CUPCAKES FROM SCRATCH

  • These chocolate cupcakes are super easy to make. It’s simply a mix and stir recipe, so you don’t need an electric mixer or any special equipment.
  • Add the dry ingredients to a mixing bowl, then add the wet ingredients, along with the buttermilk, and stir to combine.
  • To fill the cupcake liners, use a dessert spoon and a teaspoon to spoon out the batter. Just remember not to overfill your cupcake liners. They only need to be around 1/2 cup – 3/4 cup full.
  • The cakes will be ready when they spring back lightly to the touch.

How to make buttermilk from scratch

  • If you don’t have any buttermilk on hand, try making your own buttermilk from scratch. Add one tablespoon of white vinegar to 1 cup of milk. Leave for 5 minutes to curdle, then use as normal. I use this trick ALL the time because I never have buttermilk on hand.

How to make peanut butter frosting for cupcakes

  • This Peanut Butter Chocolate Cupcake recipe calls for an easy peanut butter buttercream. 
  • Make sure your butter is at room temperature – this will make it easier to get rid of any lumps and make the buttercream extra creamy.
  • Cream the butter and peanut butter together until combined, then start adding the icing sugar and milk. The buttercream will turn creamy and fluffy.

Description

Chocolate cupcakes topped with creamy peanut butter frosting.


Ingredients

Chocolate cupcakes

  • 105 grams (3/4 cup) plain flour
  • 40 grams (1/2 cup) dutch processed cocoa or regular cocoa powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 100 grams (1/2 cup) caster sugar
  • 45 grams (1/4 cup) brown sugar
  • 115 grams (1/2 cup or 1 stick) unsalted butter
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 120 ml (1/2 cup) buttermilk

Peanut butter frosting

  • 115 grams (1/2 cup) unsalted butter, softened
  • 435 grams (3 and 1/2 cups) icing or powdered sugar
  • 120 grams (1/2 cup) smooth peanut butter, plus extra for drizzling
  • 3 tablespoons milk
  • 75 grams (1/2 cup) chocolate chips

Instructions

  1. Preheat the oven to 180 C (360 F). Line a 12 hole muffin tin with cupcake liners.
  2. In a large mixing bowl, add flour, cocoa powder, baking soda, baking powder and then add the sugars. Pop the butter into the microwave for a short burst, 10 seconds or so at a time, until it becomes very soft but just before it is completely melted. Give it a stir with a fork to eliminate any lumps.
  3.  In a separate mixing bowl, add eggs, vanilla and butter and whisk together until smooth. Then add the wet mixture into the dry mixture, along with the buttermilk and gently fold until just combined.
  4. Spoon the mixture into the cupcake liners and pop into the oven. Bake for 18-20 minutes or until just cooked through. Set cakes out onto a wire rack and leave to cool completely.
  5. In a large mixing bowl, add the butter and peanut butter and beat with an electric mixer until smooth and creamy. Add the icing sugar, one cup at a time, and continue to beat. Add a tablespoon or two of milk to help loosen up the mixture. Continue to add a tablespoon of milk as needed. The icing should be nice and creamy but thick enough to hold its shape.
  6.  Pipe the frosting onto the cupcakes using a piping bag and a large round tip. Warm a little extra peanut butter in the microwave, just until smooth. Drizzle a little peanut butter on top of each cupcake and then sprinkle a few chocolate chips on top.
