To prepare your crumble topping, add your almond flour and oats to a small blender. Pulse until most of the oats have turned into a fine texture, and a few whole oats remain. Add your oat mixture to a bowl and add the maple syrup, coconut oil, cinnamon, and nutmeg. Stir until combined. Set aside.

Preheat your oven to 350 degrees Fahrenheit.

Peel and slice your peaches. Add your peaches to a 7x11 or 9x9 baking dish. Crumble your oat mixture evenly on top of the peaches.

Bake in your preheated oven for 29-33 minutes, until peaches are soft and crumble topping is golden brown. Let cool slightly before serving.
