Prep the mold: Place a silicone mini muffin mold on a sheet pan so it’s easy to move. If you don’t have silicone, line a regular mini muffin pan with paper liners to prevent sticking.
Make the strawberry swirl: Add strawberries, 1–2 tablespoons powdered sweetener, and lemon juice to a blender.
Blend until smooth. Taste and adjust sweetness. If you want a smoother sauce, strain out the seeds through a fine mesh sieve.
Whip the cream: In a mixing bowl, beat the heavy cream to soft peaks.
Set aside. This makes the bites airy and scoopable.
Make the cheesecake base: In another bowl, beat the softened cream cheese, 1/3 cup powdered sweetener, vanilla, lemon zest, and salt until completely smooth and fluffy. No lumps should remain.
Fold it together: Gently fold the whipped cream into the cream cheese mixture.
Use a spatula and light strokes to keep the mixture airy.
Fill the molds: Spoon the cheesecake mixture into each cavity, filling them about 3/4 full. Leave room for the swirl.
Add the swirl: Dollop about 1/2 teaspoon of strawberry puree on top of each portion. Use a toothpick or skewer to swirl it into the cheesecake layer with small circular motions.
Freeze: Transfer the pan to the freezer and freeze for 2–3 hours, or until the bites are firm enough to pop out cleanly.
Release and store: Push the bites out of the silicone mold.
If using paper liners, peel them away. Place the bites in a freezer-safe container with parchment between layers.
Serve: Let the bites sit at room temperature for 3–5 minutes to soften slightly before eating. The texture should be creamy and cold, not rock-hard.
