Kit Kat Cake

My Mom’s birthday is tomorrow and I decided to make her a cake. This cake is so cool looking, I think it can be used for any occasion. Since her birthday falls between Thanksgiving and Christmas, she’s getting red and green M & M’s on the top of hers. I don’t think there’s any way to mess up a cake like this. You can use a store bought cake mix and store bought frosting. I used a recipe that I found on Recipe Girl’s website and I didn’t care to much for the frosting. The taste of the frosting was really good. When I was going to attempt to frost the cake, the frosting got kind of stiff, and was hard to work with. That’s why it looks like there’s two different colors of frosting on the cake because I switched to a store bought frosting half way through. :) There’s no shame in that.

I did take a class in cake decorating once and maybe I need to re-take the class? It was fun overall and because of that class I have plenty of cake decorating supplies. It would be nice to learn how to decorate with fondant which we never learned. We just learned how to frost and make flowers out of frosting. If you’re pretty clueless when it comes to decorating a cake, like I am, try decorating a cake this way. You could even use different candies other than kit kats to decorate the edges.

CAKE: from
One 18.25-ounce box of chocolate cake mix
1 cup all-purpose flour
1 cup granulated white sugar
3/4 teaspoon salt
1 1/3 cups water
2 tablespoons vegetable or canola oil
1 teaspoon vanilla extract
1 cup sour cream
4 large eggs

1/2 cup salted butter, at room temperature
3 ounces cream cheese, at room temperature
1 pound powdered sugar, sifted
1/4 cup milk
1 teaspoon vanilla extract
1 cup dark chocolate chips (or chopped dark chocolate)

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. 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!)

2. In a large bowl, whisk together cake mix, flour, sugar and salt. Add remaining ingredients and beat with hand mixer for 2 minutes, or until well blended.

3. Scoop the batter into 6 cupcake liners 3/4-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.

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.

5. Prepare the frosting: In a large bowl, beat butter and cream cheese at medium speed with an electric mixer until creamy. Gradually add powdered sugar, beating at low speed until blended. Increase speed to medium, and slowly add milk and vanilla, beating until smooth. Microwave chocolate chips in a microwave-safe bowl at MEDIUM 1 1/2 to 2 minutes or until melted and smooth, stirring at 30 second intervals. Gradually add melted chocolate to mixture; beat until blended and smooth.

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. Stick Kit Kat’s to the sides of the cake, leaving a very small space in between each Kit Kat (1/4-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.

7. 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.


*You can certainly use your favorite layer cake recipe for this cake. The doctored-up cake mix recipe that is included here is actually quite good!

*You can also use a yellow cake or your favorite flavor… following the same instructions here for jazzing it up.
*Technically, you can use all of the batter in two 9-inch round pans, but it might make the cake too high to work for this recipe. You don’t want the cake to stand higher than the height of the Kit Kat’s- or they will not be able to act as a “fence” to hold in the M&M’s.

    Ha ha! When my Mom first looked at it she said Oh My God!

    It’s so good. Make sure to have some ice cream a long the side. It’s such a fun cake.

    I made this cake for my hubby on Friday and it was awesome. I brought the rest of it to work for people to eat it and they said it was awesome and I got a lot of compliments from it. That made me feel good :)
    I see though that I should have looked at Jenna’s blog better though because I put my kit kat bars sideways and I see hers are the long way..oops..I will try that next time! Very good cake!!
