Ingredients
- 3 tablespoons ground flaxseed meal
- 9 tablespoons water
- 2 cups all-purpose flour
- 1 3/4 cups granulated sugar
- 3/4 cup Dutch-processed cocoa powder
- 2 teaspoons baking powder
- 1 1/2 teaspoons baking soda
- 1 teaspoon salt
- 1 cup milk
- 3/4 cup vegetable oil
- 1 teaspoon peppermint extract
- 1/2 cup strongly brewed coffee
- 1 cup unsalted butter, room temperature (for frosting)
- 4 1/2 cups powdered sugar
- 3 tablespoons milk (for frosting)
- 1 tablespoon vanilla extract
- 1/2 teaspoon peppermint extract (for frosting)
- 1/2 teaspoon salt (for frosting)
- 1/3 cup heavy cream (for ganache, optional)
- 1 cup dark chocolate chips (for ganache, optional)
- 1/2 cup crushed candy canes (for topping)
Instructions
- Preheat oven to 350°F (175°C). Grease and line two 8-inch cake pans with parchment paper.
- Make flax eggs by mixing flaxseed meal with water. Let sit for 5 minutes until thickened.
- In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- In a separate bowl, whisk flax eggs, milk, oil, and peppermint extract.
- Combine wet and dry ingredients, then mix in hot brewed coffee until smooth.
- Divide batter between pans and bake for 25–30 minutes or until a toothpick comes out clean.
- Cool cakes completely on wire racks.
- To make buttercream, beat butter and powdered sugar until combined. Add milk, vanilla, peppermint extract, and salt. Beat until light and fluffy.
- Place one cake layer on a plate, frost the top, add second layer, and frost the top and sides.
- Optional ganache: heat cream, add chocolate chips, let sit, then stir until smooth. Pour over cake and top with crushed candy canes.
- Refrigerate cake for 30 minutes to set ganache if used.
Notes
- Coffee enhances chocolate flavor without adding coffee taste.
- Replace flax eggs with regular eggs if preferred (use 3 eggs).
- Use gluten-free 1:1 flour to make it gluten-free.
- Ganache adds richness and flair but is optional.
