  • 3½ cups powdered sugar
  • ½ cup cocoa powder
  • ½ cup (1 stick) butter, softened

  1. The Cake: Preheat oven to 350˚F.
  2. Grease a 9x13" baking pan. Whisk together flour, baking soda, baking powder, and salt in a bowl, set aside.
  3. Using a small bowl, whisk hot water, vanilla, & cocoa powder until smooth.
  4. Using an electric mixer beat the butter & sugar until light and fluffy. Add in 1 egg at a time. Add flour mixture in 3 additions, alternating with 2 additions of buttermilk, until combined. Reduce speed to low & slowly add cocoa mixture until incorporated.
  5. Pour batter into prepared pan.
  6. Bake for 25-30 min (mine usually takes longer) or until a toothpick inserted in the center comes out clean. Cool completely.
  7. The Frosting: Sift together the powdered sugar & cocoa in a bowl, set aside.
  8. In a large saucepan heat 4 tablespoons butter, brown sugar, salt, and ½ cup half and half over medium-low heat, stirring occasionally, until small bubbles appear around perimeter of pan, 4 to 5 minutes.
  9. Reduce heat to low, stirring frequently, until mixture thickens slightly and turns deep golden brown, about 8 minutes.
  10. Transfer to a large bowl. Stir in remaining butter & remaining half and half until butter is melted. Add the chocolate chips & the vanilla and stir until smooth. Slowly whisk in the bowl of powdered sugar & cocoa. Wait a couple minutes for it to cool then spread on cooled cake. Wait for frosting to set, then serve. (You can put it in the frig to help it set faster)
