Preheat oven to 350 degrees. Grease a casserole pan with non-stick spray. In a small bowl combine the melted butter, brown sugar, and 1 teaspoon cinnamon to make the sauce for the base of the pan. Cover the base of the cake pan with the sauce using a pastry brush. Starting from the outside perimeter and working your way towards the center, line your cake pan with the peaches and then with the blueberries. CAKE: In a medium-large mixing bowl, cream butter and sugar together until light – approx. 3 minutes. Add eggs one at a time and vanilla. Gradually add 1 teaspoon cinnamon, baking powder, salt, orange juice and flour. Mix well for 3 minutes scraping the sides and bottom down half way through. Add cake batter to the top of peaches and spread the batter evenly. Bake for 1 hour or until done. When cake is done, allow the cake to sit on the counter top for 10 minutes. Loosen the sides of the pan with a knife and flip it onto a plate. Serve warm or room temperature. Enjoy!
