Ingredients

Chocolate Cake

  • 170 g granulated sugar
  • 170 g brown sugar
  • 3 large eggs room temperature
  • 200 g unsalted butter melted
  • 160 g oil
  • 570 g milk
  • 340 g all-purpose flour
  • 130 g cocoa powder sifted if clumpy
  • 1 ½ teaspoons baking powder
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 teaspoon instant espresso powder

Peanut Butter Frosting

  • 200 g natural peanut butter
  • 230 g unsalted butter softened to room temperature
  • 100 g powdered sugar
  • 1 ½ teaspoons vanilla extract
  • 2 tablespoons heavy cream
  • Chocolate shavings

Instructions

  • Start by preheating your oven to 350°F (175°C) and lining the bottoms of two 8-inch round cake pans with parchment paper, this will help your cakes come out without a hitch.
  • In a medium bowl, mix together the flour, cocoa powder, espresso powder, baking powder, baking soda, and salt. Give it a good whisk and set it aside for now.
  • In a bigger bowl, whisk together the melted butter, oil, granulated sugar, and brown sugar until it's all smooth and blended together. 
  • Add your eggs one at a time, making sure to whisk each one in fully before adding the next. This will help your batter come together nicely.
  • Now, let’s bring the dry and wet ingredients together. Start by adding half of the dry mix to the wet ingredients and gently whisk it together. 
  • Then, add half of the milk and mix until it’s smooth. Repeat with the remaining dry ingredients and milk. 
  • The batter should be thick but still pourable, and a little lumpy is perfectly fine!
  • Divide the batter evenly between the two cake pans, filling them about ¾ of the way full.
  • Pop them in the oven and bake for 35-40 minutes. You’ll know they’re done when a toothpick comes out with a few moist crumbs. 
  • Once out of the oven, let your cakes cool in the pans for about 15 minutes. After that, gently loosen the edges with a knife and flip them out onto a wire rack to cool completely. 
  • Beat the softened butter in a large bowl with an electric mixer until it's light and fluffy, about 3-5 minutes. 
  • Gradually add the powdered sugar and keep mixing until everything is nice and airy. Then, add the peanut butter and vanilla extract, and mix until it’s smooth and creamy.
  • If the frosting feels too thick, just add a bit of heavy cream to get it to your perfect consistency.
  • When the cakes are fully cooled, place the first cake layer on a cake stand or plate. 
  • Spread a nice, thick layer of that delicious peanut butter frosting on top. Add the second layer and then spread the remaining frosting all over the top.
  • Finish it off with a sprinkle of chocolate shavings, and you’re all set!

Notes

  • Don’t rush the cooling process. Let the cakes cool completely before frosting, or the frosting might melt and slide off.
  • If your frosting feels too thick, don’t be afraid to add a bit of cream to get it nice and spreadable.
  • Don't skip the parchment paper! It’s a lifesaver for making sure the cakes slide out easily without sticking.
