Preheat oven to 350° Fahrenheit and line a small baking sheet with parchment paper.
Cut the peach in half, then remove the pit and scoop about 1 to 2 tablespoons out of the center of the peach to create a larger cavity for the crisp filling.
In a small bowl, combine the rolled oats, almond flour, melted coconut oil or butter, and maple syrup. Mix together until combined.
Place the peach halves on the prepared baking sheet, fill each peach half with the filling, then bake for 20-25 minutes. Let cool slightly before serving warm with a scoop of ice cream or dollop of whipped cream!
