Instructions
Chocolate Cupcakes
  1. Preheat oven to 175°C and centre an oven rack.
  2. Fill a 12 hole cupcake tray with paper liners.
  3. In a large bowl, sift together the dry ingredients.
  4. In another large bowl, combine the wet ingredients.
  5. Add the wet ingredients to the dry ingredients and using a whisk and starting from the centre, slow combine till you get a smooth batter.
  6. Fill each liner till ¾ full.
  7. Bake for 17-20 minutes or until a tester inserted in the middle of the cupcake cups out clean.
  8. Cool cupcake tray and fill with the remaining batter. You should have 24 cupcakes in total.
  9. Allow cupcakes to cool completely on a wire rack before frosting.
Chocolate Ganache
  1. In a small pot, heat whipping cream till bubbles form at the side. Do not allow it to boil.
  2. Pour hot whipping cream over chocolate and whisk till chocolate melts.
  3. Refrigerate till semi solid for ease of piping.
Buttercream
  1. Using a standing mixer fitted with the paddle attachment, cream together butter and peanut butter.
  2. Add sifted icing sugar and cream on medium high speed for a few minutes till the frosting is light and fluffy.
  3. Add whipping cream and cream for another minute or so.
  4. Use frosting immediately, or refrigerate it for a short while so that it can set up a little for smoother piping.
  5. If using frosting that has been refrigerated for some time, whisk it up before use.
To Assemble
  1. Fill a piping bag fitted with the filling tip with semi-solid chocolate ganache.
  2. Insert ½ way into each cupcake and fill. Do not overfill or cupcake surface may crack.
  3. Fill a piping bag fitted with the 1M open star tip with the peanut butter buttercream.
  4. Pipe swirls or ruffles on each cupcake.
  5. Refrigerate for 30 minutes to allow buttercream to set up before serving.
  6. (For more stability in the buttercream, you can replace half the butter with shortening.)
