Instructions

  1. Step 1: Preheat oven to 375°F. Peel and core apples, then cut into 1-inch chunks; place in a 9x9-inch baking dish.
  2. Step 2: In a bowl, combine 1/2 cup old-fashioned oats, 1/4 cup all-purpose flour, 1/2 cup rolled oats, cinnamon, and 1/4 tsp salt. Cut in 2 tbsp coconut oil with a pastry cutter until crumbly.
  3. Step 3: Drizzle 3 tbsp maple syrup over apples, then sprinkle oat mixture evenly over the top, pressing gently to form a crust.
  4. Step 4: Bake for 35-40 minutes until apples are bubbly around the edges and topping is golden brown. Let cool for 15 minutes before serving to set the crumble.

Frequently asked questions

How long does Cinnamon-Spiced Apple & Oat Crumble take to make?

Total time is about 55 minutes (15 min prep + 40 min cook). Most home bakers find this fits a weekend afternoon; chill or store as the recipe directs before serving.

How do I store leftover Cinnamon-Spiced Apple & Oat Crumble?

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 & Oat Crumble?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Cinnamon-Spiced Apple & Oat Crumble for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
