- 1 cup (200 g) white granulated sugar: Adds sweetness and tenderness.
- ¾ cup (180 g) whole milk at room temperature: Keeps crumb soft and moist.
- ¼ cup (56 g) unsalted butter, melted: Adds richness and depth.

How to Make Mint Chocolate Cake with Mint Chocolate Chip Buttercream Frosting Recipe
Step 1: Prepare Your Cake Batter
Start by preheating your oven to 180°C (350°F) conventional and greasing two 8-inch cake pans. Lining the bottoms with parchment paper ensures your cake layers come out flawlessly. Sift together your flour, cocoa powder, baking powder, baking soda, and salt until they’re well combined—this step is crucial for an even crumb. Then, in a separate large bowl, whisk together the sugars, milk, melted butter, vegetable oil, eggs, and vanilla extract until smooth and fully blended. Gradually add your dry ingredients to the wet mixture and stir just until combined – be gentle here to keep the cake nice and tender.
Step 2: Add the Coffee and Bake
Now pour in the hot coffee and mix until the batter is smooth. Coffee doesn’t overpower; it deepens the chocolate flavor, making this cake irresistibly rich. Divide the batter evenly between your two prepared pans, tapping them lightly on the counter to release any air bubbles. Bake for 35-38 minutes, checking doneness with a toothpick—when it comes out clean or with a few moist crumbs, your layers are ready to cool.
Step 3: Cool the Cake Layers
Allow the cakes to cool in their pans for about 20 minutes before gently turning them out onto a wire rack to cool completely. This step is key because frosting already warm cake will melt and slide off, so patience here means a cleaner, more beautiful finish.
Step 4: Whip Up the Mint Chocolate Chip Buttercream Frosting
In a large bowl, combine the room temperature butter, powdered sugar, vanilla, heavy cream, and peppermint extract. Start mixing at low speed to avoid a sugar cloud, then crank it up to medium-high and whip for at least 10 minutes for that airy, fluffy buttercream everyone dreams about. Don’t forget to scrape the sides of your bowl halfway through to ensure everything is blended evenly. Once fluffy, add the green food coloring if you want that iconic mint shade and mix until combined. Finally, fold in the finely chopped semi-sweet chocolate on low speed, giving you crunchy chocolate surprises throughout your frosting.
Step 5: Assemble Your Mint Chocolate Cake with Mint Chocolate Chip Buttercream Frosting Recipe
Trim the tops of the cooled cake layers to create flat surfaces perfect for stacking. Spread a generous layer of frosting on the first cake layer, then gently place the second layer on top. Cover the entire cake with frosting, smoothing the sides with a scraper or spatula for a polished look. Pipe a decorative border on top using a wide piping tip—smaller tips might clog with chocolate bits, so keep it simple and stunning. Slice up your masterpiece and prepare for oohs and aahs!
How to Serve Mint Chocolate Cake with Mint Chocolate Chip Buttercream Frosting Recipe
Garnishes
Consider fresh mint leaves or a sprinkling of mini chocolate chips for an added festive touch. You could even shave some dark chocolate curls over the top for elegant texture and aroma — it amps up both looks and flavor.
Side Dishes
This cake pairs beautifully with a scoop of vanilla bean ice cream or a cup of hot coffee to balance the coolness of the mint. For a refreshing contrast, serving alongside fresh berries or a light raspberry coulis is a wonderful option that complements the richness without overwhelming.
Creative Ways to Present
Try layering the cake in a trifle dish for a fun twist, or make cupcakes using this batter and frosting for an individual-sized treat perfect for parties. Another playful idea is to create cake pops with leftover crumbs and frosting—mint and chocolate combined on a stick? Yes, please!
Make Ahead and Storage
Storing Leftovers
If you have any cake left, keep it tightly covered in the refrigerator, where it will stay delicious for up to 3-4 days. The frosting may firm up but will soften at room temperature before serving — just plan ahead for that so every bite remains melt-in-your-mouth perfect.
Freezing
You can freeze this cake either before or after frosting. Wrap layers tightly in plastic wrap and foil to protect from freezer burn, then store for up to 2 months. When ready to enjoy, thaw overnight in the fridge and then bring to room temperature before frosting or serving.
Reheating
Since this is a rich, frosted cake, it’s best served chilled or at room temperature. If you prefer a slightly softer frosting, leave the slice out for 30 minutes to warm up gently. Avoid microwaving, as it can cause the frosting to separate and melt unevenly.
FAQs
Can I use regular cocoa powder instead of Dutch-processed?
Absolutely! While Dutch-processed cocoa offers a smoother taste and darker color, using natural cocoa powder will still result in a lovely cake—it just might be a little more acidic, which baking soda can help balance.
Is peppermint extract the same as mint extract?
They are quite similar but peppermint extract usually has a stronger, sharper flavor compared to the milder mint extract. For this cake, peppermint extract gives that classic refreshing minty coolness that complements chocolate beautifully.
Can I make this cake dairy-free?
You can substitute the milk and butter with plant-based alternatives like almond milk and vegan butter; however, the texture and richness might vary slightly. Just be sure your cream substitute whips well to maintain the frosting’s fluffiness.
What if I don’t have coffee on hand?
The coffee intensifies the chocolate flavor but isn’t mandatory. You can replace it with hot water, though the depth of chocolate will be a bit less pronounced.
How do I prevent the frosting from getting too soft?
Make sure all your ingredients are properly chilled and avoid over-whipping with the cream. If your kitchen is warm, refrigerate the frosting briefly before frosting your cake to keep it firm yet spreadable.
Final Thoughts
This Mint Chocolate Cake with Mint Chocolate Chip Buttercream Frosting Recipe is a truly special dessert that combines the best of two classic flavors with a texture and finish sure to impress everyone at your table.

- ½ cup (85 g) semi-sweet chocolate, finely chopped (50% dark chocolate recommended)

Instructions
- Preheat and prepare pans: Preheat your oven to 180°C (350°F) conventional. Grease two 8-inch cake pans and line the bottoms with parchment paper to ensure easy release.
- Combine dry ingredients: Sift together the flour, Dutch-processed cocoa powder, baking powder, baking soda, and salt. Whisk to combine and set aside.
- Mix wet ingredients: In a large bowl, whisk together both the brown and white sugars, whole milk, melted unsalted butter, vegetable oil, eggs, vanilla extract, and peppermint extract until well blended.
- Incorporate dry ingredients: Add the sifted dry ingredients into the wet mixture, whisking gently until just combined. Avoid overmixing to keep the cake tender.
- Add hot coffee: Pour in the hot coffee and whisk until the batter is smooth. Be careful not to overmix at this stage.
- Bake the cake: Divide the batter evenly between the prepared pans. Drop the pans lightly on the counter to release any air bubbles. Bake in the preheated oven for 35-38 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
- Cool the cakes: Let the cakes cool in their pans for 20 minutes before turning them out onto wire racks to cool completely.
- Prepare the mint buttercream frosting: In a large bowl, beat the unsalted butter, powdered sugar, vanilla extract, heavy cream, and peppermint extract first on low speed until combined, then on medium-high for 10 minutes, scraping the bowl halfway through to achieve a light and fluffy texture.
- Add color and chocolate: Mix in green food coloring, if using, until evenly combined. Then fold in the finely chopped semi-sweet chocolate on low speed to distribute throughout the frosting.
- Assemble the cake: Trim the tops of the cake layers with a serrated knife to make them flat. Place one cake layer on your serving plate and spread a generous amount of frosting over it.
- Layer and frost: Place the second cake layer on top and cover the entire cake with the remaining frosting on top and sides. Use a cake scraper for smooth edges.
- Decorate and serve: Pipe a decorative border around the top edges using a large piping tip (such as a 1M) to avoid clogging from chocolate bits. Slice and enjoy your mint chocolate cake!
Notes
- Prefer using gram measurements for accuracy in baking.
- If using a convection oven with a fan, reduce oven temperature by 20°C (about 25-30°F) to avoid overbaking.
- Use a stand or hand mixer for the frosting to achieve the best fluffy texture.
- To ensure a smooth frosting, avoid adding too much food coloring which could alter the texture.
- The strong hot coffee enhances the chocolate flavor without imparting a coffee taste.
- Ensure all refrigerated ingredients like eggs and milk are brought to room temperature before mixing for better emulsification.
