The Best Chocolate Peppermint Cake — Easy, one-bowl, no mixer cake! Decadently chocolaty, perfectly pepperminty! Your new favorite cake!!
Easy Peppermint Cake Recipe
Nothing says the holidays like chocolate and peppermint. I know Santa will approve of this cake.
I took my favorite chocolate cake, The Best Chocolate Cake With Chocolate Ganache, and adapted it for a peppermint version. 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.
My daughter loves mint desserts and was in heaven with this cake and said it’s one of her all-time favorites.
What’s in Chocolate Peppermint Cake?
To make this peppermint cake with chocolate ganache frosting, you’ll need:
- Egg
- Granulated sugar
- Sour cream
- Oil
- Peppermint extract
- Coffee
- Unsweetened cocoa powder
- All-purpose flour
- Baking soda and baking powder
- Salt
- Semi-sweet chocolate chips
- Heavy cream
- Andes Peppermint Crunch Mini Bars
How to Make Chocolate Peppermint Cake
Simply whisk together the cake batter as you normally would, being careful to let the coffee cool down before adding it to the batter.
Turn the batter into a foil-lined 9×9-inch baking dish. Bake the cake until the top has set and a toothpick or cake tester inserted in the center comes out clean.
Let the cake cool completely, then top with chocolate ganache frosting. Sprinkle with peppermint candies before the frosting sets.
Can I Omit the Coffee?
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.
Can I Double This Recipe?
I haven’t personally tried it so I cannot say for sure. The batter filled up every inch of my 9×9-inch pan, so you may have a little extra batter if you double this recipe. If that’s the case, use the extra batter to make muffins or a mini loaf — don’t overfill your pan!
Tips for Making Chocolate Peppermint Cake
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.
Make sure the coffee is somewhat cool before mixing it into the batter. If it’s piping hot, you’ll scramble the egg by mistake.
Note that you must use a 9×9-inch cake pan for this recipe. A 9-inch round cake pan is too small.

The Best Peppermint Chocolate Cake
Ingredients
Cake
- 1 large egg
- 1 cup granulated sugar
- 6 ounces sour cream, lite sour cream or Greek yogurt may be substituted
- ¼ cup canola or vegetable oil
- ½ teaspoon peppermint extract
- ½ cup brewed coffee, any temperature other than piping hot*
- ½ cup unsweetened natural cocoa powder
- 1 cup all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt, optional
Chocolate Ganache
- 9 ounces semi-sweet chocolate chips, about 1 1/2 cups
- ¾ 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
Instructions
For the 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.)
- 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.
- 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.
- Add the flour, baking soda, baking powder, optional salt, and whisk vigorously until batter has just combined, about 1 minute; don’t overmix.
- 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.
- Allow cake to cool completely in pan on top of a wire rack, at least 30 minutes, before adding ganache.
For the 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.
- 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.
- Pour cream over chocolate chips and let it stand about 1 minute.
- Whisk vigorously until chocolate has melted and mixture is smooth and combined.
- Evenly pour ganache over cake, smoothing lightly with a spatula if necessary.
- 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.
- Dice and evenly sprinkle the peppermint candies over cake.
- 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.
