  • 1 3/4 cup White granulated sugar
  • 2 1/2 tsp Baking powder
  • 1 1/2 tsp Baking soda
  • 1 tsp Salt
  • 3/4 cup Oil (canola or vegetable)
  • 2 tsp Pure vanilla extract
  • 4 Large eggs (room temperature)
  • 1 1/4 cup Buttermilk (room temperature)
  • 1 cup Hot water
  • 2 1/2 cups Unsalted butter (slightly cold)
  • 7 1/2 cups Powdered sugar
  • 1 tsp Peppermint extract
  • 1 tsp Pure vanilla extract
  • 1/2 tsp Salt

How to Make Chocolate Mint Cake

Let’s get started on this cozy baking adventure! Follow these simple steps:

  1. Prepare the Oven and Pans: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans and set them aside.

  2. Mix Dry Ingredients: In a large bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt. The rich, dark cocoa powder will make your kitchen smell like a chocolate paradise!

  3. Combine Wet Ingredients: In another bowl, whisk together the oil, vanilla, eggs, and buttermilk until well blended.

  4. Combine the Mixtures: Slowly incorporate the wet ingredients into the dry mix, stirring until just combined. Be careful not to overmix; just a gentle embrace is all they need!

  5. Add Hot Water: Gradually stir in the hot water until the mixture is smooth and velvety. This step is crucial; it makes the cake tender and moist!

  6. Bake the Cakes: Divide the batter evenly between the prepared pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pan for 10 minutes before transferring them to a wire rack to cool completely.

  7. Make the Frosting: In a large mixing bowl, beat the slightly cold unsalted butter until creamy. Gradually add the powdered sugar, peppermint extract, and vanilla extract, mixing on low until well combined. Then, add the heavy cream and a pinch of salt. Beat on high until the frosting is fluffy and light.

  8. Assemble the Cake: Once the cakes are completely cool, place one layer on a serving platter. Spread a generous layer of frosting on top, then sprinkle with chopped Andes Mints. Top with the second layer and frost the top and sides of the cake, creating a delightful minty masterpiece.

  9. Decorate: Melt the semisweet chocolate in a microwave-safe bowl at 30-second intervals, stirring in between, until smooth. Drizzle it over the frosted cake for an indulgent touch, and add extra Andes Mints on top for decoration.

Delicious Variations to Try

  • Zesty Citrus Twist: Incorporate some orange zest into your frosting for a refreshing citrus flavor that pairs beautifully with mint.
  • Chocolate Chip Cookie Layer: Add another layer of your favorite chocolate chip cookies in between the cake layers for a delightful surprise!
  • Rich Ganache Glaze: Instead of frosting, try a glossy chocolate ganache made from heavy cream and semisweet chocolate for an ultra-rich cake.
  • Nutty Addition: Fold in some crushed walnuts or pecans into the cake batter for a crunchy texture that complements the soft cake beautifully.

Chef Emma’s Helpful Tips

  • Make Ahead: You can bake the cake layers a day in advance. Just wrap them tightly in plastic wrap and store them in the fridge until you’re ready to frost and assemble.
  • Ingredient Swap: If you’re short on buttermilk, you can substitute with regular milk by adding a tablespoon of white vinegar or lemon juice.
  • Slicing Trick: For clean slices, use a warm knife – simply dip it into hot water, wipe it dry, and slice through the cake.
  • Storage Suggestions: Keep any leftover cake in an airtight container at room temperature for up to three days, or in the fridge for up to a week.
