Instructions

1. Make crust (optional):

In a bowl, mix almond flour, melted butter, sweetener, and salt until crumbly.
Press firmly into 9×9″ parchment-lined pan.
→ Chill 15 minutes to set (no-bake) OR bake at 350°F (175°C) for 10 minutes; cool completely.

2. Whip filling:

In a large bowl, beat softened cream cheese and powdered sweetener until smooth and fluffy.
Add vanilla and salt; mix until combined.
In separate bowl, whip cold heavy cream to stiff peaks.
Gently fold whipped cream into cream cheese mixture until light and airy.

3. Add confetti swirl:

Fold in sugar-free “sprinkles” or berry powder gently—don’t overmix to keep colors vibrant!
→ For marbled effect: Reserve ½ cup plain filling; tint remaining with natural food coloring. Alternate spoonfuls in pan; swirl gently with knife.

4. Assemble & chill:

Spread filling evenly over chilled crust (or directly into pan for crustless version).
Smooth top; sprinkle with optional toppings while wet.
Refrigerate at least 4 hours (or overnight) until fully set.

5. Serve:

Use parchment overhang to lift from pan. Cut into squares with a warm knife for clean edges.
Top with whipped cream, fresh berries, or extra “confetti.”
