Method

  • Preheat oven to 350 degrees & place cupcake liners in a 12-cup muffin pan
  • In a separate bowl, whisk the flour & baking soda together and set aside.
  • In a glass measuring cup, blend the hot water & unsweetened cocoa powder and set aside.
  • In large mixing bowl, cream butter and sugar together until light & fluffy. Add egg and blend well. Add vanilla & sour cream and blend well. Turn mixer down to low speed & blend in the flour/baking soda mixture. Use a spatula to scrape down the sides of the bowl & slowly add the hot water cocoa mixture, blending until combined (about 1 more minute)
  • Pour into cupcake liners and bake for 20 minutes, until toothpick inserted in center comes out clean.
  • Allow to cool on cooling rack & prepare your filling: In large mixing bowl, cream together the butter, fluff & powdered sugar.
  • Cut holes in the top of each cupcake, setting the little "caps" aside. Spoon filling into each hole & replace the caps.
  • Set cupcakes out and watch the kids devour them. Be sure and set one aside for your own inner child.
