- 1 ¾ cups (220 g) all-purpose flour
- ¾ cup (65 g) unsweetened cocoa powder
- 1 ¾ cups (350 g) granulated sugar
- 1 ½ tsp baking powder
- 1 ½ tsp baking soda
- 1 tsp fine sea salt
- 2 large eggs, room temperature
- 1 cup (240 ml) buttermilk, room temperature
- ½ cup (120 ml) neutral oil (canola or vegetable)
- 1 tsp pure vanilla extract
- 1 ¼ tsp peppermint extract, divided
- ¾ cup (180 ml) hot brewed coffee (or hot water)
- 1 cup (170 g) mini chocolate chips, tossed in 1 Tbsp flour
- Mint Buttercream
- 1 ½ cups (340 g) unsalted butter, room temperature
- 5 cups (600 g) powdered sugar, sifted
- 4–5 Tbsp heavy cream or milk, as needed
- ½ tsp peppermint extract
- 2–3 drops green gel food coloring (optional)
- Chocolate Ganache
- 4 oz (115 g) semi-sweet chocolate, finely chopped
- ½ cup (120 ml) heavy cream
- Garnish: extra mini chocolate chips & fresh mint leaves (optional)
- Prep: Pre-heat oven to 350 °F (175 °C). Grease, line, and flour two 8-inch (20 cm) round cake pans.
- Dry ingredients: Whisk flour, cocoa, sugar, baking powder, baking soda, and salt in a large bowl.
- Wet ingredients: In a second bowl whisk eggs, buttermilk, oil, vanilla, and 1 tsp peppermint extract until smooth.
- Combine: Pour wet into dry, stirring until just incorporated. Carefully stream in hot coffee; batter will be thin. Fold in floured mini chips.
- Bake: Divide batter between pans. Bake 28–32 min until a tester comes out with a few moist crumbs. Cool 10 min in pans, then invert onto racks; cool completely.
- Make buttercream: Beat butter until creamy (3 min). Gradually add powdered sugar. Beat in cream 1 Tbsp at a time to a spreadable consistency. Mix in ½ tsp peppermint extract and food coloring.
- Fill & frost: Level cake layers if needed. Place first layer on stand, spread 1 cup frosting, top with second layer. Coat cake with remaining buttercream; chill 20 min.
- Ganache: Heat cream just to a simmer; pour over chopped chocolate. Let sit 2 min, then stir until smooth. Cool 5 min.
- Finish: Drip/spread ganache over chilled cake. Sprinkle extra chips, garnish with mint leaves. Chill 15 min to set before slicing.
Notes
- Room-temp ingredients ensure an even crumb.
- Swap buttermilk + coffee with equal milk + hot water for a milder flavor.
- Cake layers freeze well (wrap tightly) up to 2 months.
- Store finished cake covered in fridge up to 4 days; bring to room temp before serving.
