Ingredients:
- 1 cup (115 g) Finely Ground Almond Meal
- 1/2 cup (45 g) Gluten-Free Rolled Oats, processed to a coarse flour
- 2 tablespoons (25 g) Granulated Sugar (for crust)
- 1/4 cup (57 g) Unsalted Butter, melted
- 1/4 teaspoon (1 g) Salt
- 1 tablespoon (10 g) Plain Gelatin Powder (unflavoured)
- 1/4 cup (60 ml) Cold Water (for blooming)
- 8 ounces (225 g) Full-Fat Cream Cheese, softened
- 1 cup (230 g) Mascarpone Cheese, room temperature
- 3/4 cup (150 g) Granulated Sugar (for filling)
- 1/2 cup (120 ml) Fresh Lemon Juice
- 3 tablespoons Fine Lemon Zest (zest of 3 large lemons)
- 1 teaspoon (5 ml) Pure Vanilla Extract
- 1/2 cup (120 ml) Heavy Cream, cold (for whipping)
- Extra Lemon Zest or Thin Lemon Slices (for garnish)
Instructions:
- Prepare the Pan and Oven: Preheat oven to 350°F / 175°C. Line the 9x9 inch pan with parchment paper, allowing an overhang 'sling' on two sides for easy removal later.
- Make the Crust: In a food processor, pulse the GF rolled oats until coarsely ground. Add the almond meal, 2 Tbsp sugar, and salt. Pulse to combine. Pour in the melted butter and pulse until the mixture resembles wet sand.
- Press and Bake: Transfer the crust mixture to the prepared pan. Press firmly and evenly across the bottom. Bake for 10–12 minutes until light golden brown. Cool completely on a wire rack.
- Bloom and Dissolve Gelatin: Sprinkle the gelatin powder over the 1/4 cup of cold water in a small bowl. Let it sit for 5–7 minutes until spongy. Heat the gelatin gently until completely dissolved and clear (Do not boil). Set aside to cool slightly.
- Whip the Cream: In a separate, chilled bowl, whip the 1/2 cup of heavy cream until medium peaks form. Set aside in the refrigerator.
- Cream the Cheeses: In the bowl of a stand mixer, beat the room-temperature cream cheese, mascarpone, 3/4 cup sugar, and vanilla extract until completely smooth, fluffy, and lump-free (about 3 minutes). Scrape down the sides often.
- Add Lemon: Gradually beat in the lemon juice and lemon zest until just combined.
- Incorporate Gelatin: Slowly drizzle the slightly cooled, dissolved gelatin mixture into the filling while the mixer is running on low speed, mixing until fully incorporated.
- Fold in Whipped Cream: Remove the filling from the mixer. Gently fold in the reserved whipped heavy cream using a spatula until no white streaks remain, keeping the filling light and airy.
- Pour and Chill: Pour the filling mixture evenly over the cooled crust. Tap the pan gently on the counter to release trapped air bubbles. Cover the pan loosely and refrigerate for a minimum of 4 hours, or ideally overnight, until the filling is fully set and firm.
- Slice and Serve: Use the parchment sling to lift the entire cheesecake block out of the pan. Cut into 12 squares using a sharp knife dipped in hot water (wipe clean between slices). Garnish with fresh lemon zest before serving.
