Easy Baked Apple Crisp (Gluten-Free + No Refined Sugar)

This Easy Baked Apple Crisp recipe uses no refined sugar, is gluten-free and a much healthier, low-carb version of a family favorite!

There’s not a whole lot that makes you feel cozier than enjoying a bowl of warm, just out-of-the-oven apple crisp.

This simple recipe is made with freshly sliced apples coated in cinnamon and honey, then topped with a sweet buttery oat crumble. The filling has a little bit of almond flour added to create a bubbling sauce that allows the natural sweetness of the sweet apples to take center stage.

We love this recipe because it uses absolutely no refined sugar, is gluten-free and a much healthier, low-carb version of a family favorite!


This is a great recipe to make with your kiddos. Kids love nothing more than getting a little messy. Have them help make the crumble topping by using a fork or their hands to squeeze and mash the butter into the mixture.

Can I prep my crisp ahead of time?

Yep! You can prep your crisp up to 24 hours ahead. Make the apple filling and store it in the fridge in an airtight container. Then, make the crumble topping and store it in a separate container or Ziplock baggie in the fridge. When you’re ready to make your crisp, remove it from the fridge, add apples to a prepared baking dish, sprinkle the topping on and bake as directed.

If you bake your crisp straight from the refrigerator (and your apples are chilled), your bake time may increase slightly.

Can I freeze my apple crisp?

Prepare and bake your apple crisp as directed. Allow it to cool completely and then cover it in a double layer of foil or with a tight-fitting lid. You can freeze you crisp for up to 2 months. Thaw it overnight in the refrigerator, then warm it low and slow in the oven—300 degrees for 25-30 minutes or until it’s heated through.

Don't have oat flour? Quickly make your own!

We use oat flour in many of our baked goods recipes. Oat flour is a nutrient-packed whole-grain flour that is naturally gluten-free. It works wonderfully in a variety of recipes to boost nutrition and flavor.

Making it is very simple! Add old-fashioned oats to a blender or food processor and blend them until they reach a fine, flour-like consistency. For a step-by-step guide including the recipe and tips, check out How to Make Oat Flour.

Some awesome ways to serve your apple crisp (warm or cold):

  • With milk or yogurt for a delicious brekkie
  • Alongside eggs or a veggie omelet
  • With a scoop of cold vanilla ice cream
  • With a dollop of Homemade Whipped Cream


  • Refrigerating your crumble topping for a few minutes prior to sprinkling it on your apples helps your butter harden back up. This allows your topping to have that awesome crumbly texture (like a streusel).
  • If you use overly tart apples, you may have to add a little more honey. If you use extremely sweet apples, you may need less. We’ve had a lot of luck with Braeburn and Granny Smith apples.
  • You can use any fruit you’d like, depending on the season. We’ve made this recipe using peaches and pears. If you try something different, be sure to share how it turned out in the comments below!
  • Some people prefer to peel their apples when making apple crisp. Because this recipe uses thinly sliced apples, and for the sake of time, we don’t typically peel our apples.
  • If you notice your crisp is starting to get overly brown (some ovens heat differently than others), loosely cover it with foil until it finishes baking.

This Easy Baked Apple Crisp recipe is made with freshly sliced apples coated in cinnamon and honey, then topped with a sweet buttery oat crumble.



Crisp topping:



Crisp topping:

  1. In a medium bowl, combine all crisp ingredients, except butter. Mix to combine.
  2. Cut butter into small cubes. Using a fork or your hands, squeeze and mash the butter into the mixture until it forms a lumpy texture. Chill the topping in the fridge until you’re ready to use it. (This allows it to firm up).


  1. Preheat oven to 325 degrees and grease a 9 x 9 baking dish.
  2. This step is key: Core and THINLY slice your apples, placing the slices in a large bowl.
  3. Gradually add flour into bowl and work into apples until they’re evenly coated. Add honey and vanilla; mix by hand. Sprinkle cinnamon over apples and mix. Once evenly coated, pour apple mixture into greased dish and spread.
  4. Sprinkle crumble mixture evenly on top of apples.
  5. Place in the oven and bake uncovered for 35-40 minutes, until crisp is golden brown and apples are soft and bubbling. If the top of your crisp begins to burn, loosely tent foil overtop. Remove from oven and allow crisp to rest for 10 minutes before serving.


Dairy-free: Replace butter with coconut oil.
