Ingredients
For the cinnamon apples:
- 6 medium apples (a mix of Honeycrisp, Granny Smith, or Gala works well), peeled and sliced
- 2 tablespoons lemon juice
- 1/4 cup brown sugar
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1 tablespoon all-purpose flour (helps thicken the juices)
- 1 teaspoon vanilla extract
For the oat crumble topping:
- 1 cup old-fashioned rolled oats
- 1/2 cup all-purpose flour
- 1/2 cup brown sugar, packed
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, melted
Instructions
1. Preheat and prep. Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch or similar-sized baking dish.
2. Prepare the apples. In a large bowl, toss the sliced apples with lemon juice to prevent browning. Add the brown sugar, cinnamon, nutmeg, flour, and vanilla extract. Stir until the apple slices are evenly coated, then spread the mixture into the prepared baking dish.
3. Make the crumble topping. In a separate bowl, combine the oats, flour, brown sugar, cinnamon, and salt. Pour in the melted butter and mix with a fork until the mixture turns into a crumbly, slightly clumpy texture.
4. Assemble. Sprinkle the oat crumble evenly over the apple layer, covering as much of the surface as possible.
5. Bake. Place the dish in the oven and bake for 35–40 minutes, or until the topping is golden brown and the apples are bubbling around the edges. If the top browns too quickly, loosely cover with foil for the last 10 minutes.
6. Cool slightly and serve. Let the dish rest for about 10 minutes before serving — this allows the juices to thicken. Serve warm, with a scoop of vanilla ice cream, a dollop of whipped cream, or simply on its own.
Tips for the Best Baked Cinnamon Apples
- Choose the right apples. A mix of sweet and tart varieties (like Honeycrisp and Granny Smith) gives the best balance of flavor and texture. Apples that hold their shape when baked, rather than turning to mush, work best — the U.S. Apple Association’s variety guide is a helpful reference if you want to experiment with different types.
- Don’t skip the flour in the filling. It helps absorb excess moisture from the apples so the filling isn’t watery.
- Cut apples evenly. Uniform slices ensure everything cooks at the same rate.
- Add texture with nuts. Chopped pecans or walnuts mixed into the crumble add a nice crunch, if desired.
- Make it dairy-free. Substitute the butter with a plant-based alternative or coconut oil for a dairy-free version.
Storage and Reheating
Baked cinnamon apples with oat crumble store well, making them a great make-ahead dessert.
- Refrigerator: Store leftovers in an airtight container for up to 4 days.
- Freezer: Freeze in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Warm individual portions in the microwave for 30–45 seconds, or reheat the whole dish in a 300°F (150°C) oven for about 10–15 minutes to help the topping crisp back up.
Frequently Asked Questions
Can I make this ahead of time?
Yes. You can prepare the apple filling and the crumble topping separately, store them in the refrigerator for up to a day, and assemble and bake just before serving.
What’s the best apple for baking?
Firmer apple varieties like Honeycrisp, Braeburn, or Granny Smith hold their shape best during baking and won’t turn mushy.
Can I use quick oats instead of old-fashioned oats?
Old-fashioned rolled oats give the best texture, but quick oats can be used in a pinch — the topping will just be slightly less chunky.
Is this recipe gluten-free?
You can make it gluten-free by using a gluten-free all-purpose flour blend and certified gluten-free oats — regular oats are often processed in facilities that also handle wheat, so look for oats specifically labeled gluten-free, as explained by the Celiac Disease Foundation.
