I am having difficulty baking a vanilla and chocolate cup-size cake. The ingredients are as follows:
12 (1 ounce) squares semisweet chocolate, chopped
1 cup butter, cut into pieces
1 cup cold milk
1 1/4 cups all-purpose flour
1 pinch salt
1 teaspoon vanilla extract
1/4 cup white sugar
The problem is that the cake burns on the outside, and then the inside is not completely done. If I reduce the amount of batter I use in the tin to a half-size cup, they end up as cookies. I have also tried to reduce the temperature from 200 degree to 100 degree, extending the time from 15 minutes to 30 minutes but still do not get a well-balanced end result.
I would like to know if I have a bad mixture of ingredients, or a completely wrong temperature and timing for cupcakes.
