Instructions
Make the raspberry coulis:
In a small saucepan, combine raspberries, sugar, and lemon juice. Cook over medium heat for 5–7 minutes until berries break down. Strain if desired. Set aside to cool.
Prepare the molten chocolate filling:
Melt dark chocolate with heavy cream in a double boiler or microwave (30-second intervals). Stir until smooth and glossy. Let it cool slightly.
Make the cupcake batter:
Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners.
In a bowl, whisk flour, sugar, cocoa, baking powder, baking soda, and salt.
In another bowl, beat eggs, oil, buttermilk, and vanilla.
Combine wet and dry ingredients, then stir in hot coffee until smooth.
Assemble the cupcakes:
Fill each liner with a spoonful of batter (about ⅓ full).
Add 1 tsp raspberry coulis and 1 tsp molten chocolate filling.
Cover with more batter until ¾ full.
Bake:
Bake for 16–18 minutes until tops are set but centers remain slightly soft.
Serve:
Let rest 2–3 minutes, then serve warm. Garnish with raspberries, powdered sugar, or ice cream.
