In a large bowl, toss together the blueberries, lemon juice and vanilla
Spoon mixture into a buttered 8-inch square baking pan
In the same bowl combine Bisquick, sugar, and cinnamon
Sprinkle dry mixture over the blueberries, then pour melted butter over the dry ingredients
Bake for 45 to 55 minutes, or until crispy
Best served warm with vanilla ice cream!
This is such an easy recipe because it is made with ingredients that I almost always have on hand. Although the recipe calls for fresh blueberries I have also made it many times with frozen blueberries. Turns out great every time!
