Ingredients

Chocolate Cake

  • 1 1/4 cups (150g) all-purpose flour, scooped & leveled
  • 2 tsp baking powder
  • 1/2 cup granulated sugar
  • 1/4 cup packed light brown sugar, how to measure brown sugar
  • 1/2 tsp salt
  • 1/2 cup Dutch-process cocoa powder, or natural unsweetened cocoa powder
  • 1 Tbsp instant coffee powder
  • 1 cup (240ml) boiling water
  • 1/3 cup extra virgin olive oil
  • 2 large eggs, at room temperature
  • 1 tsp vanilla extract

Chocolate Fudge Frosting

  • 1 1/4 cup powdered sugar
  • 3 Tbsp cocoa powder
  • 3 Tbsp (45g) unsalted butter, melted
  • 2 Tbsp boiling water

Instructions

Chocolate Cake

  • Preheat oven: Preheat the oven to 356ºF (180ºC). Line a round 8-inch baking pan with parchment paper, and set aside. Note: Alternatively, if you have a non-stick pan, liberally grease it with softened/spreadable butter and dust it with a light layer of cocoa. This will leave your finished cake with smooth sides.
  • Mix dry ingredients: In a medium-size mixing bowl, add flour, baking powder, both sugars, and salt. Whisk until well combined and set aside.
  • Sift cocoa powder: In a separate large mixing bowl, sift in the cocoa powder.
Add coffee powder: Whisk through the instant coffee.
  • Add boiling water: Pour in boiling water and whisk until the cocoa dissolves. Set aside to cool slightly for 10 minutes. If it’s still too warm to the touch, leave it for a further 5 minutes — you don’t want the eggs to curdle when added.
  • Add wet ingredients: Pour in olive oil, eggs, and vanilla. Whisk for 40 seconds until well combined.
  • Combine wet and dry: Add half of the flour mixture and whisk until just combined. Add the remaining flour and beat until incorporated, ensuring not to over-mix — just until no streaks of flour remain. Batter will be thin.
  • Pour into pan: Pour batter into the prepared pan.
  • Bake: Bake for 28–30 minutes or until a skewer inserted into the middle comes out clean or with only a few moist crumbs.
  • Cool: Remove from oven and allow to cool in the pan for 10 minutes.

Chocolate Fudge Frosting

  • Sift dry ingredients: In a medium mixing bowl, sift together the powdered sugar and cocoa powder.
  • Add wet ingredients: Pour in the melted butter and boiling water. Whisk until smooth and thick.
  • Rest to thicken: Let the frosting sit for 5–10 minutes to thicken to a spreadable consistency.
  • Frost the cake: Spoon onto the cooled cake and use a rubber spatula or butter knife to spread evenly. Add swirls if desired.
  • Set frosting: Let the frosting sit for 10–15 minutes. It won’t harden fully but will stay soft and fudgy.
  • Serve: Slice and enjoy!

Notes

Store: Keep your cake in an airtight container at room temperature, where it will stay fresh for up to three days.
Freeze: For extended storage, wrap the cake well and freeze it for up to three months.
Thaw: When ready to serve, thaw the cake in the refrigerator overnight or for several hours at room temperature until soft.
