Ingredients

For the Cake:

  • 1 cup granulated sugar
  • ½ cup unsalted butter, room temperature
  • ¼ cup extra-virgin olive oil
  • 2 large eggs, room temperature
  • 1 tbsp pure vanilla extract
  • 1 cup all-purpose flour
  • ½ cup unsweetened cocoa powder, sifted
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1 tsp salt
  • ½ cup hot water

For the Chocolate Ganache:

  • 2 cups dark chocolate, finely chopped
  • 2 tsp pure vanilla extract
  • 1¼ cups heavy cream
  • ¼ tsp salt

For the Peppermint Cream:

  • ½ cup unsalted butter, room temperature
  • ½ cup vegetable shortening, room temperature
  • 2 ½ tbsp fresh mint, finely chopped
  • 3½ cups confectioners' sugar
  • 2 tsp peppermint extract
  • 3 tbsp whole milk, room temperature

Instructions

Make the Cake

  • Preheat your oven to 350°F (177°C).
  • Grease and line a 9x2-inch round cake pan with some parchment paper.
  • In a mixer, cream together butter and sugar until fluffy.
  • Gradually add oil with the mixer on low.
  • Add eggs one at a time, followed by vanilla. Mix until combined.
  • In a separate bowl, whisk dry ingredients together.
  • Gradually add dry ingredients to the wet mix in thirds, mixing just until combined.
  • Incorporate hot water into the batter, then pour it into your prepared pan.
  • Bake for 30-40 minutes.
  • Allow to cool in the pan on a rack for 20 minutes, then remove and cool completely.

Make the Ganache

  • In a heat-safe bowl, combine salt, cream, and chocolate. Use it as a double boiler over simmering water.
  • Stir until the chocolate melts and the mixture is smooth, then add vanilla.
  • Allow to cool and thicken at room temperature (70-90 minutes).

Make the Frosting

  • Beat mint leaves, shortening, and butter together until combined.
  • Add milk, peppermint extract, and sugar, beating until smooth and creamy.

Assembly

  • Apply peppermint frosting to the cooled cake and chill in the refrigerator for 30 minutes.
  • Pour cooled ganache over the frosted cake and smooth with a spatula.
  • Chill in the refrigerator for another 30 minutes before serving.

Notes

  • For the ganache, use 2 cups of high-quality dark chocolate chips or three 4-ounce semisweet or dark chocolate baking bars.
  • Adjust salt to 1/4 teaspoon if using 70% dark chocolate, or increase to 1/2 teaspoon for sweeter variations.
  • Alternative frostings include Oreo Buttercream Frosting and Chocolate Cream Cheese Frosting.
  • Bake the cake ahead and store it at room temperature, wrapped tightly, for a day or freeze it for up to three months.
  • Prepare frosting a day early, store it refrigerated, and whisk it before use to regain creaminess. Add milk to adjust thickness.
  • Ganache can also be made a day ahead and refrigerated. Warm slightly on the stovetop to make it pourable.
  • Once assembled and frosted, the cake can be frozen for up to three months. Thaw overnight in the fridge and bring to room temperature before serving, or enjoy it cold.
  • Store any leftovers in the fridge for up to a week, ensuring they are tightly covered.
