Coolest M&Ms Cakes

This was my third grandson, Andrew’s second birthday. My daughter always seems to come up with a different homemade cake recipe for Andrew’s cakes. For this one I found a picture of the M&M man.

I used a 14” round cake pan that has a rounded top. These are a great set of pans that make an attractive cake for decorating. I use two cake mixes for this size pan. I prefer Duncan Hines cake mixes and always set the oven temperature at 315 degrees so that the cake center will rise flat and even with the sides. I also put wax paper back into the original pan and cover very well and freeze the cakes. They are easier to ice if frozen.

I made the M&M man out of fondant. It can be bought at the store and is like Play Dough. Keep it covered in a container until ready to put on the cake. The bottom border was a shell border using a large open star tip and a ruffle #101 around each shell. Peanut M&M’s were added around the cake. The writing can be directly onto the cake with a round tip. I don’t like my letter writing skills too much so I sometimes do the letters days before in royal icing. The recipe is in the Wilton book.

When finished I glued a toothpick on the back of each one with royal icing and let dry. This will keep the letters out of the icing. I put them at an angle on the cake. I like the way they look standing away from the cake. You can see that Andrew picks off the letters and eats those first!

Candy-Shaped Homemade Cake Recipe Idea

For this M&M’s homemade cake recipe idea , I used a 9″ round cake pan. I cut a little bit of the base so that it would sit up. I frosted with blue, white and black buttercream frosting and used Mr. Potato Head’s arms.
