1- Preheat and prepare. Preheat your oven to 180°C / 350°F. Prepare a muffin tray by placing paper liners in each cup and set it aside. This small step ensures even baking and effortless release.

2- Melt the chocolate. Gently melt the baking chocolate using a saucepan over low heat or in short microwave bursts. Stir until smooth, then let it cool slightly. Warm—not hot—melted chocolate blends best into the batter.

3- Mix the dry ingredients. In a large bowl, whisk together: flour cocoa powder baking powder baking soda salt This guarantees an even rise and prevents bitter cocoa pockets.

4- Combine the wet ingredients. In a separate bowl, whisk the melted butter with the sugar until glossy. Incorporate the eggs one by one, mixing thoroughly after each, then fold in the vanilla extract.

5- Bring chocolate into the batter. Slowly pour in the cooled melted chocolate, whisking gently. At this stage, the batter should look smooth and luxuriously dark.

6- Unite wet and dry mixtures. Add the dry ingredients in two parts, alternating with the milk each time.Mix just until combined—overmixing is the fastest way to lose that soft, tender crumb.

7- Fill and bake. Spoon the batter evenly into the cupcake liners, filling each about three-quarters full. Bake for 18–22 minutes, or until a toothpick inserted into the center comes out mostly clean with a few moist crumbs.

8- Cool with patience. Let the chocolate cupcakes rest in the pan for 5 minutes, then transfer them to a wire rack to cool completely before frosting or serving.
