2 cups almond flour
1/3 cup erythritol sweetener
1 tsp ground cinnamon

Directions
- Preheat the oven to 375 degrees F.
- In a medium bowl, add all ingredients for the crust. Stir to well combined and crumbly.
- Press dough firmly into a 10″ spring-form pan. Create a rim about 1/2 inch-high up the sides of the pan, using your fingers or the back of a metal teaspoon. Bake in preheated for 5 minutes.
- Combine sliced apples and lemon juice in another bowl. Stir well. Lay sliced apples evenly across the bottom of the crust in a circular pattern. Press the apples down lightly when done.

FAQ
Is Keto Apple Tart suitable for a ketogenic diet?
This tart is considered keto-friendly but not strict keto. Apples are naturally higher in carbohydrates, so while this recipe uses controlled portions and keto-approved sweeteners, it is best suited for low-carb or relaxed keto eaters rather than very strict keto diets.
Why are Granny Smith apples used in this recipe?
Granny Smith apples are lower in sugar compared to many other apple varieties and hold their shape well during baking, making them a better choice for low-carb apple-style desserts.
How many net carbs are in one serving?
Each serving contains approximately 7 grams of net carbs. Most of the carbs come from the apples, while almond flour and erythritol help keep the overall carb count lower than traditional apple tarts.
Can I reduce the carb content further?
Yes. You can reduce the amount of apples slightly or mix apples with lower-carb alternatives such as zucchini or chayote squash to lower the net carbs per serving.
Is almond flour necessary for the crust?
Yes. Almond flour is essential for keeping the crust gluten-free and low in carbohydrates. Substituting with wheat flour would significantly increase the carb count.
Can I use a different sweetener instead of erythritol?
Yes. Monk fruit sweetener or allulose can be used as substitutes. Adjust the quantity based on the sweetness level of the sweetener you choose.
Does this tart need to cool before serving?
Yes. Allowing the tart to cool helps it set properly, making it easier to slice and improving the overall texture.
How should Keto Apple Tart be stored?
Store leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat gently or enjoy chilled.
Can this tart be frozen?
Yes. The tart can be frozen for up to one month. Thaw in the refrigerator overnight before serving for best texture.
Who is this dessert best suited for?
This tart is ideal for low-carb eaters, families, or anyone looking for a lighter alternative to traditional apple desserts while still enjoying familiar flavors.
