Nothing says the holidays like chocolate and peppermint.

I love this cake because it’s a fast, easy, one-bowl, no-mixer recipe that delivers amazing results every time without being fussy or complicated.

The cake is soft, moist, decadently chocolaty, and perfectly pepperminty. The ganache is fudgy, silky, smooth, wonderfully thick and rich. It’s truly the icing on the cake.

I sprinkled the cake with diced Andes Peppermint Crunch mini bars (my grocery store was out of Andes Peppermint Crunch Baking Chips) and they add a perfect amount of crunchy texture and a nice pop of peppermint flavor.

They tend to be seasonal items and Target usually has a good selection or try a variety of grocery stores. Stores tend to carry slightly different items so what one has, another doesn’t, and vice versa. Or you can always order on Amazon. I don’t use diced hard peppermint candies because they’re too hard for my liking.

Make sure when you’re adding the peppermint extract to the cake batter that you only add 1/2 teaspoon. Peppermint extract is much stronger and more potent than vanilla extract and adding too much can cause your dessert to taste like mouthwash. Not good.

There’s coffee in the cake batter which brings out and enhances the chocolate flavor and I highly recommend it. It does not make the cake taste like a coffee-flavored cake, trust me. And we’re talking a half cup for the entire cake, just teaspoons per serving.

My daughter loves mint desserts and was in heaven with this cake and said it’s one of her all-time favorites.

Ingredients:

Cake
1 large egg
1 cup granulated sugar
6 ounces sour cream (lite sour cream or Greek yogurt may be substituted)
1/4 cup canola or vegetable oil
1/2 teaspoon peppermint extract
1/2 cup brewed coffee, any temperature other than piping hot
1/2 cup unsweetened natural cocoa powder
1 cup all-purpose flour
1 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt, optional

Chocolate Ganache
9 ounces semi-sweet chocolate chips (about 1 1/2 cups)
3/4 cup heavy cream or half-and-half
15 Andes Peppermint Crunch mini bars, diced small for sprinkling (about 1 cup; or use Andes Peppermint Crunch Baking Chips or similar diced mint candies)

Directions:

  1. Cake – Preheat oven to 350F. Line a 9-by-9-inch square baking pan with aluminum foil, spray with cooking spray, or grease and flour the pan; set aside. (Don’t use a 9-inch round pan, it’s too small.)
  2. To a large mixing bowl add the egg, sugar, sour cream, oil, peppermint extract (be careful, measure, and don’t over-add; peppermint extract is very potent), and whisk until smooth and combined.
  3. Add coffee, cocoa powder, and whisk vigorously until batter is smooth and free from lumps. Alternatively use a handheld electric mixer to quickly break up cocoa lumps. Note about coffee – The coffee does not make the cake taste like a coffee-flavored cake. Rather, it brings out and enhances the flavor of the cocoa powder and adds depth of flavor; I highly recommend coffee but use water if you must. The coffee can be any temperature other than piping hot; you don’t want to scramble the egg.
  4. Add the flour, baking soda, baking powder, optional salt, and whisk vigorously until batter has just combined, about 1 minute; don’t overmix.
  5. Turn batter out into prepared pan, smoothing the top lightly with a spatula if necessary, and bake for about 25 to 32 minutes, or until top has set and a toothpick or cake tester inserted in the center comes out clean. I’ve found that climate and brands of ingredients used impact the baking time for this cake greatly, and have baked it in as short as 25 minutes and as long as 32; bake until it’s done in your oven.
  6. Allow cake to cool completely in pan on top of a wire rack, at least 30 minutes, before adding ganache.
  7. Chocolate Ganache – To a medium microwave-safe bowl, add the chocolate chips and heat on high power for 1 minute to soften (they won’t melt); set aside.
  8. In a small microwave-safe bowl or glass measuring cup, heat the cream (I used half-and-half) on high power just until it begins to bubble and show signs of boiling, about 60 to 75 seconds.
  9. Pour cream over chocolate chips and let it stand about 1 minute.
  10. Whisk vigorously until chocolate has melted and mixture is smooth and combined.
  11. Evenly pour ganache over cake, smoothing lightly with a spatula if necessary.
  12. Allow ganache to set up and cool for about 5 minutes while you chop the peppermint candies. If you add them while ganache is too warm, they’ll melt. Too cool, and they won’t adhere; use your judgment.
  13. Dice and evenly sprinkle the peppermint candies over cake.
  14. Allow cake to cool uncovered at room temp for at least 2 to 3 hours, or until ganache has set up, before slicing and serving. I am comfortable storing this cake airtight at room temp for a day or two, and after that I store airtight in the fridge for up to 1 week. Chilling it has a nice effect with the chocolate and peppermint.

  1. Hi!
    Could I put the peppermint in the icing instead of the cake? Or would you not recommend that?
    Thanks!

  2. This looks so amazing! I love the combination of chocolate and peppermint together! So festive!

  3. Oh yum… your cake looks like it’s going to be my new favorite dessert! Looks absolutely gorgeous and oh so delicious! :) Pinned!

  4. Hi Averie,

    I haven’t commented here for a couple of weeks. Firstly this cake looks amazing. Love the fudgy layer.

    I never got to tell you that for my b-day a couple weeks ago I had asked for your cookbook. (The first one, 2nd one will come later). I have made your recipes at least 40 times this year. That’s not a joke. I never thought of getting your book if I use the site so many times but I decided to get it anyway. I love it too. :)

    Actually tomorrow I get induced for labor. Please keep your fingers crossed that I’m not in labor for too long. I want this kid out asap. When I heal completely I’ll bake some of your goodies.

    Lots of love, and stay warm

    • I can’t believe you’re writing the night before you’re going to have your baby! Best of luck!!!

      And happy belated birthday! So happy you got the book and I know you have made at least 40 this year! Some weeks you write and say you’ve made 3 or 4 in one week! Happy holidays and I hope your labor and delivery goes smoothly!!

  5. Instead of cookies this year we might just have to put this cake out for Santa instead. Because I know he would approve of this cake! It looks amazing! Pinned :)

  6. oh YES PLEASE x a million!

  7. I love anything chocolate peppermint, this is the perfect holiday cake!

  8. Oh my, this sounds fabulous! Chocolate and peppermint are my two favorite flavors. Can this be doubled in a 13 x 9 pan?

    • Haven’t personally tried it so cannot say for sure…it will be nip and tuck just because it filled up every inch of my 9×9 pan. You may have a little extra batter (don’t overfill your cake pan) and just discard or make a few muffins :)

  9. I DEFINITELY think Santa would approve of this cake! It’s so simple and decadent AND festive!

  10. This cake has me drooling! :) It’s peppermint chocolate perfection!! Pinned!

  11. Awesome post! I would never have thought about putting coffee into the cake mix, I think you’ve blown my version out of the water here :D

  12. I’m currently making a version of this and can’t wait to see how it turns out! I’ll be using chocolate buttercream instead of the ganache since I’m out of chocolate chips (a rare day), but looking forward to the finished result! I’ll let you know how it all turns out! Thanks again for the simple and delicious recipes.
