Chocolate Cupcake Recipe

  • Start by preparing the cupcakes. Preheat oven at 160C/320F. Add cupcake cases to a cupcake pan and set it aside for later.
  • Prepare dry ingredients: Add all-purpose flour, cocoa powder, baking soda, baking powder and mix until well combined. Set aside for later.
  • Prepare wet ingredients: Add unsalted butter to a bowl and whisk for 2 minutes. Then, add the caster sugar and whisk for another 3-5 minutes or until pale yellow.
  • Eggs: As you continue to whisk the mixture add one egg. Then whisk for a few minutes or until the egg disappears. Repeat this step for the remaining eggs.
  • Cupcake batter: Then, pour the wet ingredients into the dry ingredients, add milk and mix with a large spoon or spatula. Do not overmix the cupcake batter. Make sure there are still a few lumps.
  • Scoop about 2-3 tbsp of cake batter into each cupcake case and bake for 10-15 minutes.
  • Once the cupcakes are ready leave them to cool.

Chocolate Cupcake Decoration

  • Cognac buttercream: Add unsalted butter to a large bowl and whisk on a low speed for 1 minute.
  • Then add half of the icing sugar and whisk on a medium speed for 3 minutes. Add the remaining icing sugar, 3-6 tbsp of cognac, and 2-3 tbsp of double cream.
  • Whisk for 3-5 minutes or until spreadable. Add crushed pistachios to the chocolate cupcakes.
  • Add cognac buttercream to a piping bag with a star nozzle. Then add cognac buttercream on top of the pistachios.
  • Top cupcakes with more crushed pistachios and serve!


Top Tips: 
  • Do not overmix the cupcake batter as this will result in a tough and chewy cake.
  • Make sure that all of the ingredients are at room temperature before baking and making the buttercream
  • All cupcakes to cool completely before you decorate the cupcakes. If you decorate the cupcakes when they are still warm the buttercream will melt!
  • For an alcohol-free recipe skip the cognac.
