Blueberry Cream Cheese Brownie Cupcake

Ingredients for Brownies
1/2 cup unsalted butter
4 oz unsweetened chocolate, chopped
1 1/4 cup white sugar
1 teaspoon pure vanilla extract
3 large eggs
3/4 cup all purpose flour
1/4 teaspoon salt
Baking Brownies:
Preheat oven to 325 degrees. Line 12 muffin tins with paper (or foil) baking cups.
Melt butter and chopped chocolate in a stainless steel bowl placed over a saucepan of simmering water. After the chocolate is melted, remove from the heat and let cool. Stir in the sugar, and add the vanilla. Add the eggs, one at a time, mixing well after each. Stir in the flour and salt until blended. (You may also use a hand mixer.)
Divide the batter between the 12 muffin cups. Place in the oven and bake for about 20 minutes. Remove from oven and let cool.
