Instructions
- Step 1: Preheat oven to 375°F (190°C). In a 9-inch baking dish, toss 4 peeled, cored, and sliced medium apples with 1/4 cup granulated sugar, 1 tsp ground cinnamon, and 1 tbsp all-purpose flour until evenly coated.
- Step 2: In a separate bowl, combine 1/2 cup rolled oats, 1/4 cup almond flour, 1/4 cup chopped walnuts, 2 tbsp brown sugar, and 1 tsp coconut oil. Use a fork to mix until crumbly, then cut in 3 tbsp cold cubed unsalted butter using a pastry cutter until the mixture resembles coarse sand.
- Step 3: Sprinkle the crumble mixture evenly over the apples, pressing gently to compact. Bake for 35-40 minutes until the apples are bubbling around the edges and the top is golden brown and crisp.

How do I store leftover Cinnamon-Spiced Apple Crumble with Oat Crust?
Cool fully before storing. Most baked desserts keep at room temperature in an airtight container for 2–3 days, or in the fridge for up to 5 days. Cream- or custard-based desserts must go in the fridge within 2 hours; reheat gently or serve cold per the recipe.
Can I substitute ingredients in Cinnamon-Spiced Apple Crumble with Oat Crust?
