Step 1: Preheat your oven to 350°F (175°C). Grease an 8x8 inch baking dish lightly with a tiny drop of coconut oil.
Step 2: Toss your sliced apples with the lemon juice and 1 teaspoon of the apple pie spice. Layer them evenly along the bottom of your baking dish.
Step 3: In a separate mixing bowl, combine the rolled oats, almond flour, the remaining spice, and the melted coconut oil. Mix with a fork until a crumbly texture forms.
Step 4: Scatter the oat topping evenly over the apple layer. Bake for 35 to 40 minutes, or until the topping turns a beautiful golden brown and the apple juices bubble around the edges. Serve warm!
