Ingredients

Scale

  • 1 ¾ cups (350g) granulated sugar
  • ¾ cup (75g) unsweetened cocoa powder (Dutch-processed recommended)
  • 1 ½ teaspoons baking powder
  • 1 ½ teaspoons baking soda
  • 1 teaspoon salt
  • 2 large eggs, room temperature
  • 1 cup (240ml) whole milk (or almond milk for dairy-free)
  • ½ cup (120ml) vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup (240ml) boiling water
  • 1 ½ cups assorted small candies (mini M&Ms, Skittles, gummy bears, chopped candy bars)
  • Optional: sprinkles for decoration
  • For frosting (optional):
  • 1 cup (227g) unsalted butter, softened
  • 3 cups (360g) powdered sugar
  • ½ cup (50g) unsweetened cocoa powder
  • 34 tablespoons heavy cream or milk
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper.
  2. In a large bowl, sift together flour, cocoa powder, baking powder, baking soda, salt, and sugar. Stir to combine.
  3. In a separate bowl, whisk eggs, milk, vegetable oil, and vanilla extract until smooth.
  4. Slowly add wet ingredients to dry ingredients, mixing gently until combined.
  5. Carefully stir in boiling water; batter will be thin.
  6. Pour half the batter into one prepared pan and bake for 30-35 minutes. Check doneness with a toothpick.
  7. Toss candy pieces with 1 tablespoon flour to prevent sinking.
  8. Once first layer is baked and cooled about 10 minutes, place it on a cake stand or plate.
  9. Spread half the remaining batter over the first layer, leaving a small border around edges.
  10. Sprinkle floured candies evenly over this batter layer.
  11. Pour remaining batter on top, covering candies completely.
  12. Bake assembled cake for another 30-35 minutes or until a toothpick comes out clean.
  13. Cool cake in pan for 15 minutes, then transfer to wire rack to cool completely.
  14. If desired, prepare frosting by beating butter, powdered sugar, cocoa powder, cream, and vanilla until smooth.
  15. Frost the cooled cake and decorate as desired.
  16. Slice to reveal the candy-filled surprise and serve.

Notes

Flour the candies before adding to the batter to prevent sinking and color bleeding. Use thin batter consistency for moist cake. Cool cake completely before slicing to avoid melted candy mess. Avoid chocolate-covered or caramel-filled candies that melt too much.
