Chocolate Mint Layer Cake

Hi, my name is Sarah and I’m a cake-aholic.

And I am also a nutritionist.

Do we have a problem here? Not necessarily. I mean, while I absolutely love cake, I don’t eat it every day, I maintain a healthy weight, and my diet is generally (I’d like to think) pretty healthy. In fact, I’m a big fan of the 80/20 principle when it comes to eating: stay on course nutritionally about 80% of the time, do what you like–within reason–the other 20% or so. (I even wrote an article about it here.) So do I feel bad posting a totally indulgent, party-perfect Chocolate Mint Layer Cake on the blog today?

No, I actually don’t. Especially because today is my birthday.

This cake isn’t actually for my birthday (mine will be a Neapolitan Strawberry-Vanilla-Chocolate sugar bomb I intend to make this afternoon), but rather, for my mom’s a few weeks ago. My mom and I have a little arrangement where, because I love making cakes and we both love eating them, I get to make her a cake of my choosing every year. Usually with chocolate.

This year mint chocolate was calling to me, and this recipe, modified from Lindsay over at Life, Love, and Sugar was exactly what I was looking for–except that with our family size, I didn’t actually need THREE layers. (Though I may have wanted them.) The cake came out fluffy and moist and kept well in the fridge, where it shockingly actually lasted a week. And though, with mint frosting, it can be tough to strike the right non-toothpaste-y, yet not-too-mild note, this stuff does so beautifully.

I’m no cake decorating expert–I’ve taken one single class at my local Michael’s with an instructor who was oddly enthusiastic about using Snickers to garnish cakes–but I have to say, I think this, with its pretty green color and tempting Andes mint pieces, turned out looking particularly appealing. And tasted amazing. What more does a birthday cake need?

P.S. I’m not including nutrition info for this one. It’s my birthday and I DON’T WANNA KNOW!

Prep Time45 mins
Cook Time35 mins
Total Time1 hr 20 mins
Course: Dessert
Servings: 12 slices


For the cake:

  • 1 1/3 c. all-purpose flour
  • 1 1/3 c. white sugar
  • 1/2 c. cocoa powder
  • 1 1/2 tsp. baking soda
  • generous 1/2 tsp. salt
  • 1 large egg
  • 1 egg white
  • 2/3 c. milk
  • 2/3 c. vegetable oil
  • 1 tsp. vanilla
  • 2/3 c. boiling water

For the frosting:

  • 1 c. butter, softened
  • 1 c. shortening (or another cup of butter)
  • 7 1/2 c. powdered sugar
  • 3 Tbsp. water or milk
  • 1/2 tsp. vanilla
  • 2 tsp. peppermint extract
  • green food coloring, to your preference
  • yellow food coloring, to your preference
  • Andes mints, for garnish


Make the chocolate cake:

  • Preheat the oven to 300 degrees and grease two 9-inch cake pans well. In a large bowl, combine dry ingredients (flour through salt). Make a well in the center of the dry mixture and add egg, egg white, milk, and vegetable oil. Mix to combine. Add vanilla and boiling water and mix until well incorporated.
  • Divide batter evenly between the two pans and bake 30-35 minutes, or until a toothpick inserted in the center comes out clean. Cool completely.

Make the mint frosting:

  • While the cakes cool, mix softened butter, shortening, and powdered sugar until smooth. Add water or milk, vanilla, and peppermint extract and mix again. Slowly add food coloring to your liking (I'd say go with about 2/3 green and 1/3 yellow) and mix until color is even.
  • Place one layer of the cake on a platter and frost the top. Top with second layer of cake and frost the entire cake, reserving about 1 1/2 c. for extra frosting garnishes.
  • To get the look pictured, use a cake decorating tip like Wilton 1M to pipe swirls around the outer edge of the cake's surface. Insert whole Andes mints into the swirls, press them into the base of the cake, or garnish however you like!
