Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) and line a cupcake tin with cupcake liners.
  2. In a large bowl, whisk together the flour, cocoa powder, granulated sugar, brown sugar, baking soda, baking powder, and salt.
  3. In another bowl, beat the eggs and then mix in the buttermilk, vegetable oil, and vanilla extract.
  4. Gradually add the wet mixture to the dry ingredients, mixing until just combined. Carefully stir in the boiling water; the batter will be thin.
Baking
  1. Pour the batter into the prepared cupcake liners, filling them about two-thirds full.
  2. Bake in the preheated oven for 15-18 minutes or until a toothpick inserted into the center comes out clean.
  3. Allow the cupcakes to cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely.
Preparing the Buttercream
  1. In a mixing bowl, beat the softened butter until creamy.
  2. Gradually add the powdered sugar, alternating with blackberry puree, and mix until smooth.
  3. Add vanilla extract and a pinch of salt, mixing until well combined.
Frosting
  1. Once the cupcakes are completely cooled, generously frost with the blackberry buttercream using a piping bag or a spatula.

Notes

For best results, use room temperature ingredients and do not overmix the batter.
