Vanilla Cupcakes with a Melted Chocolate Center

Combine the eggs and milk, whisking for about 30 seconds until smooth.

Add the sugar and melted butter, and beat for another 30 seconds until well incorporated.

Fold in the flour, citric acid, starch, and baking powder, mixing just until a smooth batter forms.

Divide the batter evenly among the cupcake liners and bake at 170°C (340°F) for 25 minutes.

Let the cupcakes cool completely, then hollow out a small core in the center of each one.

For the chocolate filling: combine the heavy cream and chocolate in a bowl.

Heat the mixture until it reaches a boil.

Stir until completely smooth and let it cool down.

Fill the center of each cupcake with the chocolate ganache all the way to the top.

For the frosting: combine the mascarpone, powdered sugar, and cream, then whip until smooth and fluffy.
