  • 2 sticks of softened butter
  • 1 1/2 cups sugar

  • 1/2 stick of unsalted butter

  • 1 teaspoon vanilla
  • 1/8 teaspoon salt
  • 4 cups powdered sugar, sifted
  • 3 tablespoons milk or heavy cream


  1. Preheat oven to 350F.
  2. Make sure all your ingredients are room temperature. In a separate bowl, combine flour, pulverized, dried cranberries, salt, baking powder and soda; Mix to combine. Set aside.

  5. Reduce speed to low and add a cup of flour followed by 1/3 of the buttermilk. Repeat this 3 times until you have incorporated all the flour and buttermilk.
  6. Separate batter into 3 bowls, equally. Add red food coloring into 1st bowl and mix (may take a few drops depending on what brand you use).
  7. Repeat with blue food coloring in 2nd bowl. Leave batter in 3rd bowl as is.
  8. Grease three 6 inch pans and pour one bowl of batter into each pan, so each pan has a different color batter inside. Or, use two 8 inch pans and gently combine batters in a swirl or marble cake pattern in each pan. Do not over-mix or batter combination will  turn purple.
  9. Bake for 20 minutes or until a knife comes out clean. Cool for 10 minutes then remove from pan and allow to completely cool on a cooling rack.
