Why You'll Love This Recipe
This Chocolate Peppermint Cake Recipe is one of those desserts I keep coming back to during the holidays—and honestly, anytime I want something a bit special but not overly complicated. With its luscious layers and that refreshing peppermint kick, it feels like a party every time you take a bite.
- Perfect flavor balance: The warmth of cocoa powder pairs beautifully with the crisp peppermint notes, creating a flavor combo that never feels overpowering.
- Luxuriously moist crumb: Using buttermilk and vegetable oil keeps the cake tender and moist, even a day after baking.
- Show-stopping frosting: The peppermint Swiss meringue buttercream is silky, light, and can be colored however you like to match your theme or mood.
- Easy to customize: You can play with peppermint extract levels or even add coffee to the batter for depth— I'll share more on that below.
Ingredients & Why They Work
When I first put this together, I was amazed how simple ingredients combined to create such indulgent layers. The trick is using quality cocoa powder and room temperature ingredients for smooth mixing. Here’s why each piece matters:
- All-purpose flour: Gives the cake structure without being heavy, so the layers stay soft.
- Granulated sugar: Sweetens while helping create a tender texture when combined with oil and buttermilk.
- Dutch-processed cocoa powder: This mellow cocoa adds deep chocolate flavor without acidity, perfect with baking soda.
- Baking soda and baking powder: They work together for the perfect lift—baking soda reacts with acidity in buttermilk, while baking powder gives extra rise.
- Salt: Enhances the chocolate depth and balances the sweetness.
- Vegetable oil: Keeps the cake moist longer than butter would.
- Buttermilk: Adds acidity needed for lift, plus that faint tang that makes cakes taste bakery-fresh.
- Hot water or coffee: Hot liquid intensifies the cocoa flavor; coffee is optional but adds magnifique richness.
- Eggs: Provide structure and moisture; make sure they're at room temperature so they mix in evenly.
- Vanilla extract: Rounds out flavors and pairs beautifully with chocolate.
- Peppermint extract (optional): This is your minty magic—adjust to your liking for a subtle hint or bold punch.
- Egg whites and sugar (for buttercream): They create the fluffy Swiss meringue base, giving your frosting that cloud-like texture.
- Unsalted butter: Use soft, room temperature butter so it blends smoothly into the meringue.
- Color gels and powdered sugar: These help get that festive look with bright reds and pure whites for piping.
- Crushed candy canes and sprinkles: Add crunch and sparkle—these little details make the cake feel extra special.
Make It Your Way
I love how versatile this Chocolate Peppermint Cake Recipe is. Personally, I often adjust the peppermint extract depending on the occasion—sometimes just a whisper for subtle freshness, other times a full teaspoon for a bold, minty celebration. You can absolutely make this recipe your own.
- Variation: When I want an adult twist, I swap hot water for espresso—it deepens the chocolate flavor in such a delicious way that friends always ask for the recipe.
- Diet-friendly switch: Try almond milk yogurt instead of buttermilk and coconut oil instead of vegetable oil if you're going dairy-free or looking for lighter options.
- Seasonal twist: Add crushed peppermint bark on top around Christmas or mix in finely chopped candied ginger for a warming bite.
Step-by-Step: How I Make Chocolate Peppermint Cake Recipe
Step 1: Prep Your Pans and Dry Mix
Start by preheating your oven to 350°F and greasing three 6-inch round pans—don’t skip dusting them with cocoa powder; it helps the cakes release easily and adds a deeper chocolate touch. I also line the bottoms with parchment paper for smooth lifting later. Next, toss all your dry ingredients (flour, sugar, cocoa, baking soda, baking powder, salt) into your mixer bowl and stir them together so everything’s perfectly combined.
Step 2: Mix Wet Ingredients Wisely
In a medium bowl, whisk your wet ingredients—vegetable oil, buttermilk, eggs, vanilla, and peppermint extracts—together. When adding the hot water or coffee, pour it slowly while whisking to avoid cooking the eggs. This step keeps your batter silky and smooth.
Step 3: Combine and Pour Your Batter
Pour your wet ingredients into the dry mix and beat on medium speed for 2-3 minutes. The batter will be thinner than a typical cake batter—that’s just right. To ensure evenly sized layers, I use a kitchen scale to divide the batter equally across the pans. This helps with stacking and looks extra professional.
Step 4: Bake and Cool
Bake your cakes for 30-35 minutes, or until a tester comes out mostly clean. Around 30 minutes, I start checking so the cakes stay super moist. Once done, let them cool for 10 minutes in the pans before turning out onto wire racks to cool completely—this avoids soggy layers.
Step 5: Make the Peppermint Swiss Meringue Buttercream
Combine egg whites and sugar in a mixer bowl and whisk them together. Set the bowl over a pot of simmering water and whisk continuously until the mixture reaches 160°F or feels hot and no longer grainy—about 3 minutes. Then transfer the bowl back to your mixer and whip at medium-high speed until stiff peaks form and the bowl is cool, which takes around 5-10 minutes.
Switch to the paddle attachment and add your cubed butter little by little, mixing until smooth and silky. It may look curdled along the way—keep mixing, it’ll come together! Finally, stir in vanilla and peppermint extract to taste. For a festive touch, separate about 1.5 cups of the frosting and add powdered sugar and red gel coloring for vibrant red dollops. Use white color gel or a whitening trick to achieve bright white frosting.
Step 6: Assemble and Decorate
Start your stack with a cake layer, spread about ⅔ cup of buttercream on top, and sprinkle crushed candy canes if you want extra crunch. Repeat for all layers. Use the remaining buttercream for a thin crumb coat on the whole cake and chill for 20 minutes to set. Then generously frost the outside, smooth with an icing smoother or cake comb for that polished finish.
Pipe red buttercream dollops on top with a 1M tip, then pipe smaller white dollops in between with a 4B tip. Finish with crushed candy canes and sprinkles around the base for that merry sparkle.
Top Tip
From my experience making this cake several times, a few extra tips make all the difference in achieving perfection.
- Room Temperature Ingredients: Always ensure eggs and buttermilk are at room temp—they combine better for a smooth, even batter.
- Cake Layers Evenness: Using a kitchen scale to weigh batter portions eliminates guesswork and saves the headache of uneven layers.
- Buttercream Patience: The buttercream can look curdled—don't panic! Keep mixing patiently; it smooths out beautifully.
- Clean Equipment for Meringue: Make sure your bowl and whisk are totally grease-free, and no yolk sneaks into your whites, or the meringue won’t form stiff peaks.
How to Serve Chocolate Peppermint Cake Recipe
Garnishes
For garnish, I swear by crushed candy canes for crunch and color contrast. Sometimes I add mini peppermint sticks or edible silver pearls for an elegant holiday flair. These garnishes not only look festive but add a satisfying texture when you cut into the cake.
Side Dishes
I like pairing this cake with a simple cup of black coffee or peppermint hot chocolate to echo the flavors. Fresh berries or a light, fruity salad also cut through the richness nicely if serving at a party.
Creative Ways to Present
For special occasions, I've served this cake on a mirror cake stand surrounded by pine boughs and twinkling fairy lights. You can pipe peppermint leaves or chocolate shavings on top too. Another fun trick is layering the frosting in stripes inside the cake for a peppermint swirl surprise when sliced.
Make Ahead and Storage
Storing Leftovers
Wrap leftover cake slices tightly with plastic wrap or store in an airtight container in the fridge. I keep mine refrigerated especially in warmer climates because of the buttercream, and it stays fresh for about 3-4 days—sometimes longer if well sealed.
Freezing
This cake freezes well! I recommend freezing individual slices wrapped in plastic and foil rather than the whole cake. Defrost overnight in the fridge for best texture without sogginess.
Reheating
You don’t usually reheat this type of cake, but if you want to soften it up before serving, let it come to room temperature. You can briefly warm slices (10-15 seconds) in the microwave—but watch carefully, or the buttercream will melt.
Frequently Asked Questions:
Absolutely! Swap the buttermilk for a dairy-free yogurt mixed with a splash of lemon juice or vinegar as a buttermilk substitute, and use coconut oil instead of vegetable oil. For the frosting, you could experiment with a dairy-free butter alternative, but it might change texture slightly.
Keep the buttercream in an airtight container in the fridge if you’re not using it immediately. Before frosting, let it come to room temperature and re-whip briefly to restore fluffiness.
Yes! Peppermint extract is optional in the cake batter, but definitely recommended for a subtle mint undertone. If you prefer pure chocolate flavor, you can skip it, and let the frosting deliver all the peppermint punch.
This can happen if the butter is too cold or added too quickly. Make sure your butter is room temp and add it gradually while mixing on medium speed. If it curdles, keep beating—it usually smooths out after a few minutes.
Final Thoughts
Making this Chocolate Peppermint Cake Recipe always feels like a little celebration in my kitchen—a moment when simple ingredients come together to create something quite extraordinary. The balance of festive peppermint and deep chocolate is comforting yet exciting, perfect for sharing with friends or savoring quietly with a good book. I hope you try it and enjoy it as much as I do—it’s truly a sweet treat worth every step.

- Red color gel
Assembly:
- ½ cup crushed candy canes plus more for outside of cake
- Candy cane sprinkles
Instructions
- Preheat and prepare pans: Preheat your oven to 350F. Grease three 6-inch round baking pans, dust them with cocoa powder, and line the bottoms with parchment paper.
- Mix dry ingredients: In the bowl of a stand mixer fitted with a paddle attachment, combine all dry ingredients and stir until well blended.
- Whisk wet ingredients: In a medium bowl, whisk together the wet ingredients, adding the hot water or coffee slowly to avoid cooking the eggs if it is very hot.
- Combine batter: Add the wet ingredients to the dry and mix on medium speed for 2-3 minutes. The batter will be very thin.
- Distribute batter and bake: Pour the batter evenly into the prepared pans using a kitchen scale if available for accuracy. Bake for 35 minutes or until a cake tester comes out mostly clean.
- Cool cakes: Let the cakes cool in the pans for 10 minutes, then remove and place on wire racks to cool completely.
- Prepare Swiss meringue: Combine egg whites and sugar in a stand mixer bowl. Place the bowl over a hot water bath and whisk constantly until the mixture is hot to the touch (about 3 minutes) or reaches 160F on a candy thermometer.
- Whip meringue: Transfer bowl to the stand mixer and whisk on medium-high speed until stiff peaks form and the bowl is no longer warm (about 5-10 minutes).
- Add butter to meringue: Switch to the paddle attachment and add the cubed butter slowly while mixing until the mixture becomes smooth.
- Flavor and color buttercream: Add vanilla and peppermint extract, mixing until smooth. Set aside 1 ½ cups of buttercream, add powdered sugar and red color gel to create the red frosting. Use bright white color gel to whiten the remaining buttercream if desired.
- Assemble cake layers: Place one cake layer on a serving plate or stand. Spread about ⅔ cup buttercream over it, sprinkle with ¼ cup crushed candy canes, and repeat for remaining layers.
- Crumb coat and chill: Apply a thin crumb coat over the assembled cake and smooth the sides. Chill the cake for 20 minutes.
- Final frosting and smoothing: Generously frost the outside of the cake, smooth with an icing smoother, and use a cake comb on sides repeating to achieve a smooth finish.
- Decorate cake: Pipe dollops of red buttercream on top using a 1M piping tip, then pipe smaller white frosting dollops between them with a 4B tip. Decorate the bottom edge with crushed candy canes and sprinkles as desired.
Notes
- Ensure no egg yolks are present in the egg whites and that all equipment used for meringue is completely grease-free to achieve stiff peaks.
- If the buttercream looks curdled during mixing, continue mixing until it becomes smooth and creamy.
- Use hot coffee instead of water to enhance the chocolate flavor in the cake if desired.
- Bright white color gel helps neutralize the natural yellow tint in the buttercream for a cleaner white finish.
- Using a kitchen scale to evenly distribute batter ensures uniform cake layers which results in a balanced assembly.
