Serves: 8


  • 2 cups granulated sugar
  • 1 3⁄4 cups flour, sifted
  • 1 3⁄4 cups unsweetened cocoa powder, sifted, divided
  • 1 1⁄2 teaspoons baking powder
  • 1 1⁄2 teaspoons baking soda
  • 1⁄2 teaspoon salt, plus a pinch
  • 2 large eggs, room temperature
  • 1 cup buttermilk, room temperature (or substitute with 1 cup milk)
  • 1⁄2 cup vegetable oil
  • 4 teaspoons vanilla extract, divided
  • 1 cup hot coffee (or substitute with 1 cup boiling water)
  • 1 1⁄2 cups unsalted butter, room temperature
  • 4 1⁄2 cups powdered sugar, sifted
  • 4 tablespoons heavy cream, room temperature
  • M&M’S® White Pumpkin Pie candies
  • SNICKERS®, TWIX®, 3 MUSKETEERS® and MILKY WAY® Fun Size Candy Bars
  • Drizzle of chocolate syrup


  • Preheat oven to 350°F and grease and cocoa powder two 9” cake pans.
  • In a mixing bowl, sift together sugar, flour, ¾ cup cocoa powder, baking powder, baking soda and ½ tsp. salt, then mix together with a whisk.
  • In a separate bowl, combine eggs, buttermilk, oil and 2 tsp. vanilla extract.
  • Add wet ingredients to dry ingredients 1 cup at a time and mix on medium-low. Once wet ingredients have been incorporated, mix on medium for two minutes.
  • Stir in hot coffee last. Batter will be thin.
  • Pour batter evenly into the two prepared cake pans and bake for 30-35 minutes.
  • Allow cakes to cool for 20-30 minutes in pans, then invert onto a wire rack to continue cooling.
  • To make icing, beat together butter and remaining vanilla in stand mixer or using handheld mixer on medium-high until light and fluffy.
  • In a separate bowl, sift together powdered sugar, 1 cup cocoa powder, and pinch of salt with a whisk. Add dry ingredients to the butter one cup at a time and mix. With the mixer on medium-low, slowly add the heavy cream. Once the heavy cream is incorporated, mix on medium for 2 minutes. Frosting will darken as it sets.
  • To assemble cake, smooth a dollop of frosting onto cake stand, then place the first cake layer on stand with the bottom side down. Coat top of the cake generously with frosting, allowing a bit of frosting to overhang the edges.
  • Add second cake layer with bottom side up and push down until even. Generously frost the top, then sides, of the cake.
  • Decorate top of the cake with chopped and whole SNICKERS®, TWIX®, 3 MUSKETEERS® and MILKY WAY® Fun Size Candy Bars as well as M&M’S® White Pumpkin Pie candies.
  • Drizzle cake lightly with chocolate syrup.
