To prepare a sugar free peach and banana cobbler recipe, you will need: 1 cup peeled and quartered peaches, 2 cups sliced bananas, 1/2 cup sugar, 1 tablespoon vanilla, and 1/2 teaspoon cinnamon. Preheat the oven to 350?F (180?C) and grease and flour 2 8-inch pie pans. Mix the dry ingredients with the wet ingredients until the mixture resembles coarse crumbs. Add the sugar mixture and stir to combine. Pour the batter into the pie shells and bake for 35 to 40 minutes or until browned. Remove from oven and let cool before serving.
