Peanut Butter and Chocolate Cupcakes

Moist and nutty peanut cupcakes, topped with a creamy chocolate buttercream and sweet, crunchy peanut brittle.


Bank Holiday Monday meant lots of extra time for baking, and as I was away on holiday last week, I was raring to get back to the kitchen!

I have bean meaning to make a chocolate and peanut butter dessert for a while, and I recently had an amazing dessert of chocolate fondant and peanut butter ice cream, which reminded me of what a delicious combination it is! This weekend I decided that it was time to get out the peanut butter!


I made a peanut butter flavoured cupcake, topped with a chocolate buttercream, and for a bit of extra fun, I made peanut brittle for decoration.

I took these into work and everyone loved the flavours and was super impressed with the peanut brittle, so a great recipe if you want to show off your baking skills to your friends!

I will be bringing them along to Fiesta Friday#70 this week, hopefully people will be just as impressed!


Variations: You could use any other nut butter in the sponge – chocolate and hazelnut would be a lovely combination.


Ingredients: Makes 12 Large cupcakes

The Sponge:

  • 150g butter
  • 150g caster sugar
  • 2tbsp peanut butter
  • 100g peanuts
  • 2 eggs
  • 150g self raising flour

The Peanut Brittle:

  • 100g peanuts
  • 150g granulated sugar
  • 2 tbsp water

The Chocolate Buttercream:

  • 200g butter
  • 500g icing sugar
  • 2tbsp cocoa powder


To Make:


The Sponge:

Preheat the oven to 180C, and line a 12 hole cupcake tray with muffin cases.

Blitz the peanuts in a small blender to a coarse powder.

Cream together the butter, sugar and peanut butter, until light and fluffy. Then fold in the eggs, one at a time, followed by the ground peanuts and flour.

Spoon the mixture into the muffin cases until 2/3 full. Bake in the preheated oven for 12-14 minutes, untill cooked through and golden brown.

Leave to cool on a wire rack before icing.

The Peanut Brittle:

Grease and line a baking tray.

In a small pan combine the sugar and water, cook over a medium heat until the mixture turns a dark golden brown colour, stir in the peanuts.

Pour the peanut mixture onto the baking tray and smooth out into a thin layer, leave to cool completely, until hard.

Blitz half the brittle into a coarse powder, and smash the other half into small clusters.

The Buttercream:

Whisk together the butter, coca powder and icing sugar, until smooth and glossy. It should hold its shape when mixed.



Spoon the buttercream into a piping bag with a star shaped nozzle and pipe a swirl of buttercream onto the top of each cake.

Sprinkle some of the blended peanut brittle over the top of each cake, and then decorate with a few pieces of peanut brittle.

Serve up the cupcakes, and enjoy!
