Ingredients

  • 125 g all-purpose flour
  • 175 g granulated sugar
  • 64 g unsweetened natural cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon fine sea salt
  • 120 g buttermilk room temperature
  • 120 g sour cream room temperature
  • 120 g canola oil
  • 1 large egg (≈ 50g)
  • 1 teaspoon vanilla extract
  • 120 g hot water + 2 teaspoon espresso powder OR 120g (½ cup) hot coffee
  • 1 teaspoon peppermint extract
  • Peppermint cream cheese frosting (one batch)
  • Garnish: crushed peppermint candy optional

Instructions

  • Preheat the oven to 350°F (180°C). Spray an 8×8-inch baking pan (or a 9-inch round) with nonstick cooking spray or line with parchment paper and set aside.
  • In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt then set aside.
  • In a medium bowl, whisk together the buttermilk, sour cream, oil, egg, and vanilla until well combined.
  • Add the wet ingredients to the dry ingredients and stir until mostly combined. Combine the hot water/coffee mixture with the peppermint extract in a small cup. Pour the coffee mixture into the batter and whisk until combined and smooth.
  • Pour the batter into the prepared pan and tap the pan firmly on the counter to release any air bubbles. Bake for 28-30 minutes, until the cake is puffed and a toothpick inserted into the center comes out clean.
  • Allow the cake to cool for 15 minutes in the pan. Then remove the cake from the pan and set it on a cooling rack to cool completely while you make the peppermint cream cheese frosting.
  • Spread the peppermint cream cheese frosting evenly over the top of the cooled snack cake. Top with crushed candy canes, if desired.
