Ingredients

Chocolate cake:

  • 1/2 cup sugar
  • 1/2 cup brown sugar
  • 1 teaspoon Vanilla
  • 1/2 cup butter softened
  • 2 large eggs
  • 3/4 cup all-purpose flour
  • 1/2 cup cocoa powder unsweetened
  • 2 tablespoons coffee
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 cup chocolate chips

Chocolate Buttercream (optional):

  • 1 cup unsalted butter softened to room temperature
  • 3 1/2 cups confectioners’ sugar
  • 1/2 cup cocoa powder unsweetened
  • 3 tablespoons milk
  • 2 teaspoons vanilla extract
  • pinch salt

Instructions

Chocolate cake:

  • In a large bowl, using an electric mixer, beat sugars, vanilla, and butter until light and fluffy.
  • Beat in eggs, one at a time until well-combined.
  • Beat in coffee.
  • In a small bowl, whisk together the flour, cocoa powder, baking powder, and salt.
  • Slowly add flour mixture to the butter mixture and beat until well-combined. Scrape the sides and the bottom of the bowl from time to time.
  • Stir in the chocolate chips.
  • Spray an 8-inch springform pan with nonstick cooking spray.
  • Spoon the batter into the pan and smooth the top.
  • Cover loosely with aluminum foil. Place on a wire trivet with handles.
  • Pour 1 cup of water into the Instant Pot. Lower the wire trivet with the cake onto the bottom of the pot.
  • Lock the lid into place and point the valve to sealing.
  • Pressure Cook or Manual on high pressure for 30 minutes. Let sit to Naturally Release Pressure for 10 minutes. Use Quick Pressure Release to release the remaining pressure.
  • Serve as is or wait for the cake to cool and top with buttercream.

Chocolate Buttercream (optional):

  • Using a handheld or stand mixer fitted with the whisk attachment beat the butter on medium speed until creamy for about 2 minutes.
  • Add confectioners’ sugar, cocoa powder, heavy cream, salt, and vanilla extract. Beat on low speed for 30 seconds, then increase to high speed and beat for 1 minute.
  • Add 1/4 cup more confectioners’ sugar if the frosting is too thin or another tablespoon of milk if frosting is too thick.
  • Use immediately or cover and refrigerate for up to 1 week. Beat before using on the cake.
  • Frost the cake, garnish with berries, chill for 1 hour and serve.

Notes

  • Don’t overmix the ingredients! Otherwise, you will activate the gluten and make the cake tough.
  • Leave a little space when you cover with foil because the batter will expand as it cooks.
  • For the coffee, we love using espresso for the best flavor.
