Ingredients
For the Apple Filling:
- 4 medium Granny Smith apples (or another tart variety), peeled, cored, and thinly sliced
- 2 tablespoons lemon juice
- 1/4 cup erythritol or monk fruit sweetener
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1 teaspoon vanilla extract
- Pinch of salt
For the Crisp Topping:
- 1 cup almond flour
- 1/4 cup coconut flour
- 1/3 cup erythritol or monk fruit sweetener
- 1 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, cold and cut into small cubes
- 1/3 cup chopped pecans or walnuts (optional, for extra crunch)
Step-by-Step Instructions
1. Prepare the Apple Filling
Preheat your oven to 350°F (175°C). In a large bowl, toss the sliced apples with lemon juice, sweetener, cinnamon, nutmeg, vanilla extract, and a pinch of salt. Ensure the apple slices are well coated with the spices and sweetener.
Transfer the apple mixture into a greased 8×8-inch baking dish or similar oven-safe dish, spreading evenly.
2. Make the Crisp Topping
In a mixing bowl, combine almond flour, coconut flour, erythritol, cinnamon, and salt. Add the cold butter cubes and use your fingers or a pastry cutter to blend the butter into the flour mixture until it resembles coarse crumbs.
If using nuts, fold them into the topping mixture for added texture.
3. Assemble and Bake
Sprinkle the crisp topping evenly over the apple filling. Bake in the preheated oven for 35–40 minutes or until the topping is golden brown and the apple filling is bubbly and soft.
4. Cool and Serve
Allow the apple crisp to cool slightly before serving. It’s delicious warm on its own or topped with keto-friendly whipped cream or sugar-free vanilla ice cream.
Tips for the Best Keto Apple Crisp
- Apple variety: Tart apples like Granny Smith work best because their flavor balances the sweetness of the topping.
- Don’t skip the lemon juice: It prevents the apples from browning and adds a subtle brightness.
- Butter temperature: Using cold butter in the topping helps achieve that perfect crumbly texture.
- Sweetener options: Adjust the amount and type of sweetener based on your preference for sweetness and how your sweetener bakes.
Nutritional Benefits
This dessert offers fiber from the nuts and coconut flour, healthy fats from the butter and nuts, and a moderate amount of protein. It’s a great way to enjoy a classic dessert flavor while staying within keto macros.
