Instructions
**Chocolate Cake:**
- Preheat your oven to 350°F and prepare a 9×9-inch cake pan with parchment paper and butter/oil.
- If making your own buttermilk, mix 2/3 cup milk with 2 tsp vinegar or lemon juice, stir, and set aside.
- In a bowl, mix the flour, sugar, baking powder, baking soda, and salt. Sift to remove any lumps.
- Add the egg, vegetable oil, and buttermilk. Whisk until combined.
- In a smaller bowl, mix the boiling water with cocoa powder and instant coffee until smooth and shiny.
- Add the cocoa mixture to the batter and gently fold until combined.
- Pour the batter into the prepared pan.
- Bake for about 23-25 minutes, until a toothpick inserted into the center comes out with moist crumbs.
- Let the cake cool in the pan for at least 20 minutes.
**Mascarpone Whipped Cream:**
- Whisk the chilled heavy cream, sugar, and vanilla in a bowl until it thickens (do not overmix).
- Add the mascarpone cheese in two additions and mix on low speed until combined. The mixture should be thick and fluffy. Avoid overmixing to prevent graininess.
**Assembly:**
- Once the cake has cooled, carefully remove it from the pan and trim off the crust.
- Clean the pan and line it with two sheets of parchment paper, leaving the edges overhanging.
- Transfer the cake back into the pan, with the trimmed side up.
- Use a pastry brush to generously brush the strong coffee or espresso over the cake.
- Spread the mascarpone whipped cream evenly over the cake.
- Refrigerate for about 6 hours, or ideally overnight, to set.
- Once set, carefully lift the cake out of the pan using the parchment paper edges and place it on a serving board.
- Dust the top with cocoa powder using a sifter.
- Slice, serve, and enjoy!
