240 g all-purpose flour
395 g sugar
65 g unsweetened cocoa powder
2 tsp (8 g) baking powder
1.5 tsp (9 g) baking soda
1 tsp (2.5 g) kosher salt
1 tsp (2.5 g) espresso powder
225 ml milk
1/2 cup (99 g) vegetable oil
2 large (100 g) eggs
2 tsp vanilla extract
225 ml boiling water
Preheat oven to 350F/175C. Prepare two 9-inch cake pans by spraying with baking spray or buttering and lightly flouring.
Add flour, sugar, cocoa, baking powder, baking soda, salt and espresso powder to a large bowl or the bowl of a stand mixer. Whisk through to combine or, using your paddle attachment, stir through flour mixture until combined well.
Add milk, vegetable oil, eggs, and vanilla to flour mixture and mix together on medium speed until well combined. Reduce speed and carefully add boiling water to the cake batter until well combined.
The cake batter will be very thin after adding the boiling water. This is correct and results in a delicious and moist chocolate cake.
Distribute cake batter evenly between the two prepared cake pans. Bake for 30-35 minutes, until a toothpick or cake tester inserted in the center of the chocolate cake comes out clean.
Remove from the oven and allow to cool for about 10 minutes, remove from the pan and cool completely.
Frost the cake with Chocolate Buttercream Frosting.
Frosting:
130g softened butter
200g sugar
50g cocoa powder
1 tsp espresso powder
50ml milk
Dissolve espresso powder in a little but of boiling water then mix with milk.
Whisk butter, sugar, cocoa powder and coffee/milk until smooth.
