Instructions

For the cake:

  • Preheat oven to 350 degrees.
  • Grease and flour two 9 inch pans, line bottom with parchment paper circles and set aside. I USED  THREE 6 INCH PANS. THIS WILL MAKE TWO SMALL 3-LAYER CAKES.
  • In a bowl of stand mixer, stir together flour, cocoa, sugar, baking soda, and salt.
  • Add eggs, buttermilk, melted butter, and vanilla; beat until smooth, about 2 to three minutes.
  • Remove bowl from mixer and stir in hot coffee with rubber spatula, the batter will be very runny.
  • Pour into pans and bake on middle rack for 35 minutes or until toothpick comes out clean with a few crumbs attached.
  • Allow to cool on wire rack for 15 minutes.
  • Run a butter knife around the pan.
  • Invert pans onto racks.
  • Cool completely before frosting

For the frosting:

  • Mix all dry ingredients together.
  • Add butter and slowly add cream and milk to achieve desired consistency.
  • Mix for 3 minutes with electric mixer to get the frosting creamy and fluffy.
