Gluten-Free Lemon Blueberry Cheesecake Bars with Almond Crust and Aquafaba Topping

Almond Flour: Use finely ground, unsweetened almond flour for the best texture in the crust. Nut-free alternatives like gluten-free oat flour or sunflower seed flour can be used, but will slightly alter flavor.

Maple Syrup or Honey: Both sweeten naturally. For vegan or dairy-free versions, use maple or agave syrup instead of honey.

Coconut Oil: Melted coconut oil binds the crust and imparts subtle flavor. Neutral oils like vegetable or light olive oil are alternatives; avoid extra virgin olive oil due to its strong taste.

Cream Cheese: Choose regular or dairy-free cream cheese softened to room temperature for smooth blending.

Fresh Lemons: Use fresh lemons for juice and zest to get bright, natural citrus flavor instead of bottled lemon juice.

Blueberries: Gently fold fresh blueberries into the cheesecake filling to avoid breaking. Frozen blueberries may be used but thaw and drain thoroughly to prevent excess liquid.

Aquafaba: The chickpea liquid replaces egg whites in the topping. Use chilled aquafaba from canned chickpeas for best whipping results. Avoid liquid from dried beans or homemade chickpeas due to inconsistent texture.

Cream of Tartar: Stabilizes aquafaba. If unavailable, lemon juice or white vinegar can substitute but may slightly alter flavor.

Powdered Sugar: Use sifted powdered sugar to sweeten and stabilize the aquafaba topping. For lower sugar, reduce amount or use an appropriate powdered sugar substitute.
