Moist, rich chocolate cupcakes made in one bowl — simple enough for beginners, but impressive enough for any celebration.
1 cup (120g) all-purpose flour
½ cup (45g) unsweetened cocoa powder
¾ cup (150g) granulated sugar
½ tsp baking soda
¼ tsp salt
1 large egg
½ cup (120ml) buttermilk
¼ cup (60ml) vegetable oil
1 tsp vanilla extract
½ cup (120ml) hot water or hot coffee
Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
Whisk flour, cocoa, sugar, baking soda, and salt in a large bowl.
Add egg, buttermilk, oil, and vanilla. Mix until smooth.
Slowly stir in hot water or coffee. Batter will be thin.
Fill liners ⅔ full.
Bake for 17–20 minutes or until a toothpick comes out with moist crumbs.
Cool 5 minutes in pan, then transfer to a wire rack. Frost when fully cool.
Dutch-process cocoa gives a smoother flavor.
Add chocolate chips for extra indulgence.
Unfrosted cupcakes freeze well for up to 3 months.
