First, wash and dry your blueberries. Make sure any little stems and leaves are removed. Next, spray the inside of the Crockpot with the non-stick spray. In a large bowl or in the Crockpot combine the blueberries, brown sugar, cinnamon and cornstarch. Mix until the blueberries are coated. Remove the biscuits from the can and slice them into fourths. Place the quartered biscuits on top of the blueberry mixture in the Crockpot. Place the cover on the Crockpot and bake on high for 2-3 hours. When the biscuits have browned and the blueberries are bubbling then it's time to eat!Enjoy with whipped cream or a side of vanilla ice cream. Check out our other Crockpot Recipes.
