Servings 16 servings


  • 1 cup unsweetened cocoa powder (like Hershey's)
  • 1 1/2 cups boiling water
  • 3 large eggs
  • 3/4 cup vegetable or canola oil
  • 1/2 cup sour cream
  • 2 teaspoons vanilla
  • 2 1/2 cups flour
  • 2 cups sugar
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 2/3 cups chocolate chips


  • 8 ounces cream cheese, room temperature
  • 1/2 cup butter, room temperature
  • 3 cups powdered sugar
  • 1/2 cup unsweetened cocoa powder (like Hershey's)


  • 13 Kit Kat Bars (about 52 individual kit kat pieces)
  • green food coloring
  • candied flowers (optional)
  • Peppa Pig figurines


  • Preheat oven to 350 degrees. Grease two 9-inch round cake pans with cooking spray and line the bottoms of the pans with parchment paper rounds. Set aside.
  • In a medium bowl, whisk the cocoa powder and boiling water until smooth. Set aside to cool slightly.
  • In a large bowl, add the eggs, oil, sour cream, and vanilla and beat with a hand mixer until smooth, about a minute. In a separate bowl, whisk the flour, sugar, baking powder, baking soda, and salt. Add to the wet ingredients and and gently fold in the dry ingredients. With hand mixer on low, slowly pour in the cocoa/water mixture until combined, using a rubber spatula to finish mixing together the ingredients. 
  • Divide batter between prepared pans (a kitchen scale is great to ensure equal amounts). Sprinkle in 1/3 cup of chocolate chips into each of the pans. Bake for 40-45 minutes, or until toothpick inserted in middle of cake comes out clean. Transfer to baking racks and let cool for 10 minutes before removing cakes from pan to cool completely. Once completely cooled, transfer to freezer for 10 minutes to harden slightly. 
  • Meanwhile, prepare the frosting. In a stand mixer fitted with paddle attachment, or in a large bowl with a hand mixer, cream together the cream cheese and butter until creamy, about 3 minutes. Add in the powdered sugar and mix until well combined. Remove about 1/2 cup of the frosting to a small bowl with a couple drops of green food coloring, stir and set aside. Add the cocoa powder to the remaining large batch of frosting and mix until fluffy, about a mintue.
  • Place the bottom layer of cake on the cake pedestal and trim to flatten the top. Add a scoop of the chocolate frosting and spread to about 1/4 inch thickness. Add on the top layer of cake and frost the remaining cake, including the sides, reserving about a tablespoon of the chocolate frosting.
  • Break apart the Kit Kat bars to four individual pieces. Stick the bars to the side of the cake until entire cake is covered.

  • Spread the remaining tablespoon of chocolate frosting in the middle of the cake to look like a muddy puddle. Position the figurines around the puddle.

  • Place the green frosting in an icing bag fitted with a grass tip. Pipe on "grass" around the top edge of the cake and use decorative edible flowers if desired.
