Grandma was a Bisquick user, and going through a box that belonged to her I found a ton of her recipes, some readable, some not.
2 Tbsp. cornstarch
3/4 Cup sugar
1 tsp. cinnamon
1 Cup water
1 1/2 Cups blackberries
1 Cup homemade bisquick
2 tsp. sugar
2 Tbsp. butter, melted
1/4 Cup milk
Preheat oven to 400° F. Combine water, sugar, cornstarch, cinnamon and blackberries. Bring to boil. Cook for 2 minutes.
Pour into casserole dish and cover with topping.
Mix Bisquick, sugar, butter and milk.
Bake until golden, about 25 to 30 minutes.
Serve with Ice Cream or Whipped Cream.
