When ready to eat, preheat the oven to 325°F (163°C). Place the apple fritters on a baking sheet lined with parchment paper and bake for 10-12 minutes until heated through. You can also reheat them in the microwave for 30 seconds or until warmed through.  Keep in mind that reheating in the oven or the microwave won't give you the same texture that you enjoyed when you first made this gluten-free apple fritters recipe.
