This M&M Cake is a chocolate lovers' dream dessert! It is perfect for a birthday cake but also can be a very festive cake for any occasion by using different colored M&M's.
This cake is a winner in our house! It is made with M&M’s and Kit Kat bars, two of our kind favorite candies. You can never go wrong with those two mixed into a recipe!
The M&M Cake is very easy to make. And it looks so pretty once it is finished!
We have made this for birthdays using regular colored M&M's, at Christmas with the red and green M&M's and for the Fourth of July using red, white and blue.
If you can't find the festive colored M&M's at your local store, you can most likely find them on Amazon.
I use a store bought white cake mix and frosting to save time when making this cake. However, if you would rather make the cake and frosting from scratch, here is a great recipe for both.
How to make M&M Cake:
Start with making your cake according to the box directions for either the 8 or 9" cakes (I use 9" cake pans for this recipe). You will need two round cakes. Let the cakes cool completely before decorating it.
While the cakes are cooling, unwrap the KitKat bars and set them aside. When I use a 9" cake pan I used 12 - 4 piece candy bars (or 42-46 individual KitKat bars).
Once the cakes are cooled, remove them from the pans. Place each one on a dinner/serving plate (with one being the plate you plan on serving the cake on) and frost the two individual cakes. Frost the cake that is on the serving plate first and then place the other cake on top and frost that one.
The frosting does not need to look perfect as it will be covered with the candy.
Break the KitKat bars into two pieces and gently place them vertically along the edge of the cake. Try to keep them in order of breaking them so that the cracks in the bars will match up.
Pour the M&M’s onto the cake until the top of the cake is covered with the candy.
Optional: Once you have all the candy on the cake, take a ribbon and wrap it around the cake. Doing this makes the cake look more festive. The frosting will hold the KitKat bars in place if you choose not to use the ribbon.
Look for festive colored M&M's a few weeks ahead of the holiday that you are making this for. Sometimes the stores run out of them closer to the day.
When breaking the KitKat bars, keep them in order so that the cracks on the sides of the bars match up and it looks neater.
Make sure you add the KitKat bars and M&M's right after frosting the cake. The frosting acts like a glue to hold the candy to the cake so you want to add them right away.
Making this on a warm day?
Place the KitKat bars in your refrigerator until you are ready to use them. Otherwise they might start to melt a little from the warmth of your hands in the heat.
Keeping the cake in the refrigerator after you add the candy helps so the chocolate does not melt if it is a warmer day.
