A Kit Kat Cake is a cake made with store-bought cake mix and gets topped with M & M's and Kit Kat's around the edge of the cake.


  • 1 15.5 oz box of chocolate cake mix
  • 1 1/4 cups water. 
  • 1/3 cup vegetable oil
  • 3 eggs
  • 2 16 oz container of chocolate frosting (a extra for incase you run out)
  • Three 4.5-ounce Giant Kit Kat Bars (you'll need 36 Kit Kat sticks total)
  • One 12.6-ounce bag M&M's


  1. Heat oven to 350 F 
  2. Grease  9in round cake pans with cooking spray. 
  3. 2. Beat cake mix, water, oil and eggs in large bowl on low speed 30 seconds, then on medium speed 2 minutes, scraping bowl occasionally. Pour into pan.
  4. 3. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let the cakes completely cool for 10 minutes before removing from pan. Cool completely before frosting. 
  5. 4. When the cake is cool, you're ready to assemble. Place one layer on a serving plate, and tuck strips of waxed paper underneath the sides of the cake.
  6. 6. Frost the 1st cake layer. Set the 2nd layer on top of the first. Frost the 2nd layer and along the sides of the cake too.
  7. 7. Stick Kit Kat's to the sides of the cake, leaving a very small space in between each Kit Kat (1/4-inch). Fill the top of the cake with M&M's. Pull out the strips of waxed paper and discard. Use any extra frosting to frost your 6 extra cupcakes.
  9. 8. If you refrigerate the cake for a couple of hours or so, it will be much easier to cut and serve.
