Preheat oven to 350 degrees F (175 degrees C). Generously spray a 12-cup fluted tube pan with cooking spray.
Mix 1/2 cup sugar, flour, 1/2 teaspoon cinnamon, and 1/4 cup melted butter together in a bowl; sprinkle over the greased sides and bottom of tube pan.
Separate biscuit dough into 16 biscuits; cut each biscuit into 4 pieces.
Mix 3/4 cup sugar and 1 tablespoon cinnamon together in a bowl. Pour 1/2 cup melted butter into a separate bowl.
Dip each biscuit piece in the 1/2 cup melted butter; roll in the cinnamon-sugar mixture until well coated. Toss coated biscuit pieces and blueberries together in a large bowl; arrange biscuits and blueberries in the prepared fluted tube pan. Drizzle with 1/4 cup butter and any remaining butter from dipping.
Bake in the preheated oven until biscuits are golden brown, 20 to 30 minutes. Cool in the pan for 5 minutes before inverting onto a serving platter.
