Kit Kat Cake


For my friend’s birthday (the same friend that made the Polka Dot Cookies with me), I decided to make a cake that my mom has made before on her blog. Since my friend’s favorite candy is Kit Kats, I made a Kit Kat Cake. I supposed that if he liked Kit Kats, he MUST like M&Ms.

Kit Kat Cake

Whoa. I would be horrified to know how many calories are in this cake. The M&Ms and Kit Kats alone would be a TON of calories, but with cake and frosting too? Crazy.

The process of decorating the Kit Kat Cake is pretty time consuming. You have to surround the cake with M&Ms at the bottom of the cake. After that last step, you need to gently press the Kit Kats into the cake just above the M&Ms.

The Kit Kats need to be a very small space apart or else the M&Ms on top will slip through the open space.

My famous saying in this photo is: “To dump M&Ms, or not to dump M&Ms.” In this case, dump the M&Ms. But even though you dump the M&Ms on top, you still need to make sure that the M&Ms aren’t all piled up on one side. Try to even it out.

When you’re done with the cake, take two awesome colors of ribbon and wrap it around the Kit Kats. It’s a very clever idea. I only had three colors of ribbon, so I chose red and blue over yellow. Only now do I realize my cake looks like a presidential election cake.

I was proud of my masterpiece and still am. All Kit Kat Cakes look as majestic as mine (but mine is a little grander than most people’s cakes… because I made it!). 🙂

I might be able to take down the cake in one bite!! I don’t really think so though.

My friend, his family, and I LOVED this cake. I realized a measurement unit for cake slices too! You can use the Kit Kats to measure! For example: A three Kit Kat slice. The piece would be cut so that three Kit Kats are on the end your slice. In my opinion, the cake tasted perfect but chocolate is my life so other people might have different tastes than me (no pun intended). Any chocolate lover like me will want to marry this cake like the man who marries bacon in the Jack in the Box commercial. As the commercial says: “You may now eat the bride.”

And even a kid can create puns without realizing it… Like Me!

  • 2 tubs of chocolate frosting (or make your favorite frosting recipe)
  • Three 4.5-ounce Giant Kit Kat Bars (you'll need 36 Kit Kat sticks total)
  • One 12.6-ounce bag of M&M's
  • Ribbon


  • Preheat oven to 325°F. Grease and flour two 9 inch round cake pans and line a cupcake pan with 6 liners (you're going to have 6 cupcakes to munch on along with your cake!)
  • In a large bowl, whisk together cake mix, flour, sugar and salt. Add remaining ingredients and beat with hand mixer or a whisk for 2 minutes, or until well blended.
  • Scoop the batter into 6 cupcake liners ¾ full. Divide the remaining batter into the prepared round pans. Bake the cupcakes for about 25 minutes, and bake the cake rounds about 35 to 40 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool in the pan for 20 minutes, then remove the cake layers to a wire rack to cool completely.
  • 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.
  • 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. Stick Kit Kat's to the sides of the cake, leaving a very small space in between each Kit Kat (¼ inch). Wrap a bow around the cake, securing the Kit Kat's. 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.
  • If you refrigerate the cake for a couple of hours or so, it will be much easier to cut and serve. Of course, you'll need to remove the bow just before serving.

I made one of these for my son's birthday. Delicious beyond all reason, but I decided to sit down and figure out exactly how many calories it contained.

10,757 for the whole cake using:

3 cups Bulk Barn Deluxe Chocolate Cake Mix (requires 120mL Vegetable Oil and 150mL whole egg) 720g Bulk Barn Chocolate Icing 480g M&Ms 39 Kit Kat fingers.

That's 828 calories for a 3 Kit Kat-wide slice. Crazy.

I would like to know why did you add extra ingredients to the cake batter? I want to make this cake this week still, but would like to know why they were added if the batter only needs eggs, water and oil usually thank you

It's my mom's recipe, and the extra ingredients make a boxed cake taste a million times better.
