Easy Apple Crumble with Oats and Maple Syrup
This healthy apple crisp has been my favorite fall dessert since I started (very losely) adapting Ina Garten’s old-fashioned apple crisp years ago. The original is incredible but heavy on white sugar, butter, and white flour, so I recreated it with maple syrup, coconut oil, and oat flour instead. The result tastes just as cozy and comforting, but it’s lighter, refined-sugar free, and naturally gluten and dairy free, so I feel good about serving it on weeknights as well as holidays.
The oat topping really is what makes this crisp. Stir the oats, oat flour, salt, cinnamon, maple syrup, and melted coconut oil together until everything looks evenly moist and slightly crumbly, then scatter it over the apples in irregular clumps rather than a smooth layer. Bigger, craggy pieces give you that signature crisp top with deeper pockets of caramelized topping baked in!
The other thing worth knowing is that this is a true crowd-feeding recipe! It makes enough to serve 8 to 10, it can be assembled ahead and baked just before serving, and leftovers are so lovely for a snack or even breakfast the next morning. Serve it warm on its own or with vanilla ice cream (highly recommend!), and if you love this oat topping, my maple oat mixed berry crisp uses the same approach perfect for berry season. And for another easy apple dessert in the same comfort-food lane, my slow cooker apples make a great hands-off topping for yogurt or oatmeal too!


Robyn’s Testing Tips for Healthy Apple Crisp with No Sugar
- Don’t skip the citrus zest and juice in the filling, since when I tested without it the apples tasted flat; the orange and lemon brighten everything and balance the maple sweetness!
- I make my own oat flour by blending whole rolled oats in a high-speed blender until it forms a coarse flour, which is cheaper than store-bought and works just as well; use certified gluten free oats if that matters to you.
- This is one of the few desserts I happily eat for breakfast the next morning, so when I make it ahead I scoop leftovers over a bowl of yogurt and call it a meal. Perfection!
- When I want extra crunch in the topping I add half a cup of chopped pecans or walnuts; it bumps it from “feels healthy” to “tastes a little indulgent” without changing the prep at all.


Healthy Apple Crisp (With Oats)
Ingredients
- 5 pounds apples, peeled, cored, and thinly sliced
- 1 orange, zest grated and juiced
- 1 lemon, zest grated and juiced
- ¼ cup pure maple syrup
- 1 teaspoon cinnamon
For the Topping:
- 1 ½ cups oat flour
- 1 cup old-fashioned whole rolled oats
- ½ teaspoon salt
- 1 teaspoon cinnamon
- ⅓ cup melted coconut oil
- ⅓ cup pure maple syrup
Equipment
Instructions
- Preheat the oven to 350 degrees. Grease a 9×14 baking dish with coconut oil or spray with cooking spray.
- Combine the apples, orange and lemon zests, orange and lemon juices, ¼ cup maple syrup, and 1 teaspoon cinnamon in the baking dish, stirring well.
- To make the topping, combine the oat flour, whole oats, salt, 1 teaspoon cinnamon, ⅓ cup maple syrup, and melted coconut oil. Stir until well combined and crumbly. Scatter evenly over the apples.
- Place the crisp on a sheet pan lined with foil and bake for 50-60 minutes, until the top is brown and the apples are bubbly.
Notes
- Make sure the oat flour and whole oats are labeled gluten-free for gf diets.
- Any apple works in this crisp, but I typically use a mix of sweet and tart apples for the best flavor; my go-to combo is half Honeycrisp or Pink Lady for sweetness and half Granny Smith for that tart bite that keeps it from feeling cloying.




This looks amazing and is totally happening for Thanksgiving!
Julie, fantastic. I hope you have a wonderful holiday!
Planning on making this for Christmas Eve, can’t wait but confused on one part of the directions. Do you mean to put foil on top of the crisp while baking? If the crisp is in a baking dish I’m unclear about the sheet pan part. Thanks for clarifying, love all your recipes!
Hi Madeline, no I do not put foil over the while baking because I found the the topping doesn’t brown and crisp if covered. Keep an eye on it toward the end of cooking and if it starts to brown too much feel free to cover with foil. I place the sheet pan under the baking dish because sometimes the fruit juices run over and can leave a sticky mess in the oven if there’s not something under to catch it. Happy you’re enjoying the recipes–Merry Christmas!
I made this last weekend and I just have to say that it’s THE tastiest refined-sugar-free apple dessert I have ever made. Our dwarf apple trees are loaded right now so I was looking for a healthy dessert to make with them. I used 12 apples (about 3.75 pounds) because I didn’t think any more would fit in my 9×13 pan without risk of making a mess. I also omitted the orange (because I didn’t have one) and the recipe still turned out great. I’m new to your site and can’t wait to try more of your recipes.
Kelly, I’m so glad you enjoyed the recipe and that you were able to put the apples from your trees to good use. I hope you continue to enjoy other RFWL recipes as well! 🙂
Made this tonight for dessert to use up some apples and it was delicious! Hubby and kids all approved. I used all sweet apples so it turned out very sweet, yum! The topping is amazing!
Stephanie, yay, so happy to hear this was a hit with you and your crew!
Super delicious and healthy! My one year old loves it too!!
Kate, yay, so happy to hear you and your fam are enjoying this one. Thanks so much for taking the time to leave a review!
