Ingredients
Method
- Preparing the Cupcake Batter
- Preheat oven to 175°C (350°F) and line a 12-cup muffin tin with cupcake liners.
- In a large bowl, sift together flour, cocoa powder, baking soda, baking powder, and salt. Set aside.
- In another bowl, whisk together both sugars and oil until well combined. Add eggs one at a time, followed by vanilla extract.
- Alternate adding dry ingredients and buttermilk into the wet mixture. Mix gently with a spatula.
- Pro Tip: Avoid overmixing stop when no flour streaks remain.
- Slowly pour in hot coffee and whisk until the batter is smooth and slightly runny.
- Making the Blackberry Compote
- In a saucepan, combine blackberries, sugar, and lemon juice. Cook on medium heat (5-7 minutes) until berries release juices.
- Stir in cornstarch slurry and cook another 2 minutes until mixture thickens slightly. Remove from heat and cool completely.
- Baking the Cupcakes
- Divide batter evenly into liners, filling each about ⅔ full.
- Bake for 18-22 minutes, or until a toothpick inserted comes out with a few moist crumbs.
- Cool cupcakes in the pan for 5 minutes, then transfer to a wire rack to cool fully.
- Preparing the Frosting
- Beat softened butter in a stand mixer for 2-3 minutes until pale and fluffy.
- Add powdered sugar gradually, then mix in vanilla and cooled blackberry compote.
- Adjust with heavy cream for a silky, pipeable consistency.
- Assembling & Decorating
- Once cupcakes are cool, use a paring knife or cupcake corer to cut small holes in the center.
- Fill each with a spoonful of cooled blackberry compote.
- Pipe blackberry frosting over the top using a piping bag.
- Garnish with fresh blackberries, mint, and chocolate shavings.
