Ingredients:
- 1.5 cups (190g) all-purpose flour
- 1 cup (200g) granulated sugar
- 0.5 cup (45g) unsweetened cocoa powder
- 1 tsp (5g) baking powder
- 0.5 tsp (3g) baking soda
- 0.5 tsp (3g) salt
- 1 large (50g) egg
- 0.5 cup (120ml) buttermilk
- 0.5 cup (120ml) vegetable oil
- 1 tsp (5ml) vanilla extract
- 0.5 cup (120ml) boiling water

- 0.5 cup (115g) unsalted butter
- 3 cups (360g) powdered sugar
- 1 tsp (5ml) vanilla extract
- 2 tbsp (30ml) heavy cream
Instructions:
- Whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt in a large bowl until no lumps remain.
- Add the egg, buttermilk, oil, and vanilla. Whisk by hand until the batter is smooth and glossy.
- Carefully stir in the boiling water by hand to bloom the cocoa and create a thin batter.
- Divide the batter evenly among 12 lined cupcake tins, filling each only 2/3 full.
- Bake at 350°F (175°C) for 17 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
- Cool cupcakes in the tin for 5 minutes, then transfer to a wire rack to cool completely.
- Beat softened butter and cream cheese until pale and fluffy. Gradually add powdered sugar, vanilla, and heavy cream until silky.
- Pipe or spread the frosting onto the completely cooled cupcakes.
