Apples: select firm apples with no bruises or brown spots. The best varieties for apple crisp are mentioned below.
Apple pie spice: a blend of cinnamon, nutmeg, and allspice.
Maple syrup: goes into the topping and filling and can be swapped with honey.
Coconut oil: used in the crumble topping to make it crisp and delicious. Butter can also be used.
Walnuts: for extra crunch, this could also be pecans.

Best Apples for an Apple Crisp

While you can use ANY apple to make this dessert, the best options include Granny Smith, Pink Lady, and Honey Crisp!

Their crisp texture can handle the oven’s heat without turning into apple sauce, and their sweet-tart flavor gets even better as the sugars caramelize.

My mouth is watering just typing that out!

How to Make an Apple Crisp with Oat Flour

Grab those ingredients, tie on a kitchen apron, and let’s make an apple crisp worthy of first place at the county fair!

Prep
Wash, peel, and slice the apples. Preheat the oven to 350F and grease a 9-inch baking dish.
Make the apple filling
Toss the apples with the apple pie spice and maple syrup. Transfer to the baking dish.
Prepare the crumble topping
Process the melted coconut oil, walnuts, oat flour, maple syrup, unsweetened coconut flakes, vanilla extract, apple pie spice, and salt in a food processor until everything breaks down into a crumbly paste.
Bake to perfection
Spread the topping over the apples and bake for 45 minutes or until the top is golden brown and the apple center is bubbling.
Cool off
Allow the apple crisp to cool for 30 minutes before serving (otherwise, you run the chance of scalding everyone’s mouth).

Keeping it Crispy

Before baking, the apple crisp topping should resemble coarse wet sand crumbles. If the topping is too wet and doesn’t hold the crumble, place it in the refrigerator to chill for 5 to 10 minutes before distributing it over the apples. Otherwise, it will bake into a doughy consistency.

Make sure you don’t scrimp on the oil or melted butter either- it’s the key to a good crisp texture.

Substitutions and Swaps

For a perfect topping and apple filling, it’s important to use all the ingredients listed and their specified amounts. Since this isn’t a flour-based recipe, the amount of oil, walnuts, oat flour, and coconut flakes are exact and shouldn’t be altered.

The only substitutions I can confidently recommend include:

Butter vs. coconut oil (a 1:1 swap)
Pecans vs. walnuts (a 1:1 swap)
Cinnamon vs. apple pie spice (reduce the amount by half)

Prep Time: 30 minutes
Cook Time: 45 minutes
Total Time: 1 hour 15 minutes
Yield: 8
Category: Dessert
Method: Baked

Ingredients

Apple filling:

6 medium apples, peeled and sliced to a ¼-inch thickness*
1 ½ teaspoons apple pie spice
1 tablespoon (15 ml) maple syrup

Crumble Topping:

⅓ cup melted coconut oil
1 cup walnuts
¾ cup oat flour
2 tablespoons maple syrup
⅔ cup unsweetened coconut flakes
1 teaspoon vanilla extract
2 ½ teaspoons apple pie spice
⅛ teaspoon salt

Instructions

Preheat your oven to 350F. Grease a 9-inch pie dish or baking dish with coconut oil.
In a large bowl, toss the sliced apples with the spices and maple syrup. Transfer to the baking dish.
For the crisp topping, combine all the ingredients in a food processor and process or pulse until the pecans are finely ground and the dough forms a thick, crumbly paste
If your topping isn’t thick, you can chill it for 5-10 mins in the fridge. Spread the topping over the apple to completely cover.
Transfer to the oven and bake for 45 minutes or until the apples are bubbling and the topping is brown and crisp. If the top browns too soon, you can cover it with aluminum foil part of the way through.
Let sit for at least 30 minutes to cool down before serving warm.
