The image shows three baked stuffed bell peppers in a white baking dish with a white marbled texture background. Each pepper has two layers: the bottom layer is a soft, cooked yellow-green pepper that looks juicy and tender, while the top layer is a thick, crumbly mixture of oats and brown sugar, giving a rough, grainy texture. The filling has browned slightly on top, with some syrupy juices spreading around the peppers inside the pan. A wooden spatula rests on the side of the dish, partially covered with the syrupy sauce.

Simple ingredients often make the best dishes, and this Bake Apples with Oatmeal Crumble Recipe is no exception. Each ingredient plays a key role, from the juicy apples that provide natural sweetness and moisture, to the cinnamon and coconut sugar that add warm, fragrant notes. The oats and oat flour come together to create that irresistible crumble texture, all tied together with rich coconut oil for a subtle buttery flavor without dairy.

  • 2 large apples (Honeycrisp recommended): Their crispness and sweet-tart flavor stand up perfectly to baking.
  • ½ cup hot water: Keeps the apples moist while baking and prevents drying out.
  • 1 tablespoon coconut sugar: A natural, lightly caramel-flavored sweetener that complements the fruit brilliantly.
  • ½ teaspoon cinnamon: Adds warmth and enhances the apple’s natural flavors.
  • ⅓ cup rolled oats: Provides texture and heartiness to the crumble topping.
  • ⅓ cup oat flour: Helps bind the crumble and adds tenderness.
  • ¼ cup coconut sugar: Sweetens the crumble topping with a less processed touch.
  • ½ teaspoon cinnamon: Sprinkles a little extra spice to the crumble for depth.
  • 3 tablespoon coconut oil or vegan butter: Gives the topping a rich, luscious finish without dairy.
  • ⅛ teaspoon salt: Enhances all the natural flavors and balances sweetness.

How to Make Bake Apples with Oatmeal Crumble Recipe

Step 1: Prepare the Oven and Apples

Start by preheating your oven to 375°F. While it heats up, carefully slice your apples in half and use a spoon to remove the seeds and core, giving you gorgeous apple boats ready to cradle the crumble topping.

Step 2: Arrange Apples in the Baking Dish

Pour the half cup of hot water into an 8 x 8-inch baking dish to keep the apples tender. Place the apple halves skin side down in the pan, so they soften evenly while baking.

Step 3: Sprinkle Sugar and Spice

Sprinkle each apple half with coconut sugar and cinnamon. This simple dusting helps caramelize the apples as they bake, making the flavors pop with a natural sweetness and warm spice.

Step 4: Make the Oatmeal Crumble

In a bowl, combine rolled oats, oat flour, coconut sugar, cinnamon, and salt. Add the coconut oil or vegan butter, and use your hands to mix everything together until crumbly. It should hold together when pressed but remain crunchy.

Step 5: Top the Apples and Bake

Press the crumble mixture firmly over each apple half, creating a generous topping. Pour any leftover crumble straight into the pan around the apples; it will bake into a delicious oatmeal. Cover with foil and bake for 25 minutes, then remove the foil and bake uncovered for another 15 to 20 minutes until the apples soften and the topping turns golden and crisp.

Step 6: Serve Warm

Once baked, serve your apples warm straight from the oven. They pair spectacularly with a scoop of vanilla ice cream or a drizzle of plant-based cream for an extra indulgent touch.

How to Serve Bake Apples with Oatmeal Crumble Recipe

A white bowl holds a dessert with two main layers and a topping. The bottom layer is yellow and soft, looking like baked fruit. On top, there is a thick brown crumbly layer that has a rough texture with small oat pieces. Two pale cream-colored scoops of melting ice cream sit partly on the crumble and partly on the bowl, blending into the dessert. A fork is placed on the right side, digging into the dessert and holding a mix of the yellow base and brown crumble. The background is a white marbled surface.

Garnishes

A sprinkle of chopped nuts like walnuts or pecans adds a delightful crunch on top of the crumble. Fresh mint or a dusting of powdered sugar can also create a visually appealing and refreshing contrast to the warm spices.

Side Dishes

This Bake Apples with Oatmeal Crumble Recipe shines as a dessert but also pairs well with breakfast sides like creamy yogurt or a cozy bowl of hot porridge, making it a versatile dish you can enjoy any time of day.

Creative Ways to Present

For a charming presentation, serve the baked apples in individual ramekins with the crumble stacked high. Alternatively, scoop the crumble topping over sliced baked apples served on a pretty plate, then drizzle with maple syrup or honey for added sweetness and flair.

Make Ahead and Storage

Storing Leftovers

Leftover baked apples with oatmeal crumble can be stored in an airtight container in the fridge for up to 3 days. To retain the crumble’s crispness, store it separately if possible and reheat just before serving.

Freezing

You can freeze this dessert by tightly wrapping the baking dish in foil or transferring portions to freezer-safe containers. Freeze for up to 2 months, and thaw overnight in the refrigerator before reheating to enjoy later.

Reheating

Reheat leftovers in a preheated oven at 350°F for about 10-15 minutes, uncovered, to bring back the warmth and crisp up the crumble again. Microwaving works for a quick fix but the texture won’t be quite as delightful.

FAQs

Can I use a different type of apple for this recipe?

Absolutely! While Honeycrisp apples provide a nice balance of sweetness and tartness with firm texture, varieties like Fuji, Pink Lady, or Gala will also work well. Just keep in mind firmer apples hold their shape better during baking.

Is this recipe vegan?

Yes, it can be entirely vegan by using coconut oil or vegan butter as the fat source. Coconut sugar and oats are plant-based as well, making this a great dessert for a vegan-friendly menu.

Can I make this recipe gluten-free?

Definitely. Since this recipe uses oat flour and rolled oats, ensure you buy certified gluten-free oats and oat flour if you need to avoid gluten. The other ingredients are naturally gluten-free.

What can I substitute for coconut sugar?

If you don’t have coconut sugar, you can substitute brown sugar, maple sugar, or even light molasses for a similar caramel-like sweetness and color. Just adjust the quantity to taste.

How do I prevent the crumble topping from getting soggy?

Using cold coconut oil or vegan butter and working it quickly into the dry ingredients helps create those lovely crumbly bits that crisp up when baked. Also, baking uncovered at the end ensures moisture evaporates and the topping stays crunchy.

Final Thoughts

This Bake Apples with Oatmeal Crumble Recipe is truly a little slice of cozy heaven. With its simple but flavorful ingredients and straightforward steps, it’s a treat any home cook can whip up to impress friends or simply enjoy a comforting moment solo. Once you try it, you’ll understand why it’s become such a favorite—warm, tender apples combined with a buttery, spiced oat topping just can’t be beat. I encourage you to dive in and make this recipe yours, savoring every wonderful bite.

Instructions

  1. Preheat Oven: Preheat your oven to 375°F to prepare for baking the apples with the crumble topping.
  2. Prepare Apples: Slice the apples in half and carefully spoon out the centers to remove the seeds, creating a cavity.

Notes

  • You can substitute honeycrisp apples with Fuji, Gala, or Granny Smith apples depending on your preference for sweetness or tartness.
  • For a richer crumble, swap coconut oil with vegan butter or regular butter if not vegan.
  • If oat flour is unavailable, you can blend rolled oats into a fine powder to make your own.
  • Be careful not to overbake apples; they should be tender but still hold their shape.
  • Leftover crumble baked in the pan turns into a delicious oatmeal that can be enjoyed alongside the apples.
  • Serve with a scoop of vanilla ice cream or whipped cream for extra indulgence.

Welcome to Recipes By Lea

I spent most of my twenties working as a freelance travel photographer, bouncing between cities for weeks at a time. Lisbon, Istanbul, Bangkok, Mexico City—wherever a client needed architecture, street life, and local culture captured in a real, honest way. It was exciting and fast, but it also meant inconsistent routines and way too many meals that came from cafés, room service, or whatever I could grab between shoots.
