3 cups blueberries
1 cup raisins
1 cup finely chopped blueberries
3 tablespoons butter
1 cup milk
1 teaspoon vanilla extract
Preheat oven to 375 degrees F (190 degrees C). Grease and flour two 9-inch round cake pans.
Combine blueberries and raisins in a small bowl. Mix butter, milk and vanilla in the bottom of a medium serving dish. Spread blueberry mixture over top.
Bake in preheated oven for 1 hour, or until bubbles of blueberry mixture burst. Allow to cool completely. Cut into 1/2-inch squares.
