Prep the pan: Set your oven to 325°F (163°C). Line the bottom of a 9-inch springform pan with parchment paper. Lightly spray the sides with nonstick spray.
Make the crust: In a bowl, mix almond flour, sweetener, melted light butter, vanilla, and a pinch of salt until the mixture looks like damp sand.
Press evenly into the pan. Use the bottom of a measuring cup to pack it tightly.
Par-bake the crust: Bake for 8–10 minutes until lightly golden at the edges. Let it cool while you make the filling.
Melt the white chocolate: Combine the chopped white chocolate with milk.
Microwave in 15–20 second bursts, stirring between each, until smooth. Set aside to cool slightly so it’s warm, not hot.
Beat the cream cheese: In a large bowl, beat light cream cheese with a hand mixer on medium speed until very smooth and fluffy, about 1–2 minutes. Scrape down the sides.
Add sweetener and flavors: Beat in the granulated sweetener, vanilla, lemon juice, and a pinch of salt until smooth.
Add yogurt: Mix in the Greek yogurt on low speed just until combined.
Avoid overmixing, which adds air and leads to cracks.
Blend in eggs: Add the eggs one at a time on low speed, mixing just until incorporated.
Stir in the chocolate: Slowly stream the melted white chocolate into the batter while mixing on low. Scrape the bowl and fold to ensure even distribution.
Fill and smooth: Pour the batter over the cooled crust. Tap the pan gently on the counter a few times to release air bubbles.
Run a spatula over the top to smooth it.
Bake: Bake at 325°F (163°C) for 35–45 minutes. The edges should be set, and the center should jiggle like gelatin, not slosh. Avoid overbaking.
Cool gradually: Turn off the oven, crack the door, and let the cheesecake rest inside for 30 minutes.
Then move it to a wire rack to come to room temperature.
Chill overnight: Cover and refrigerate for at least 6 hours, ideally overnight, to set the texture and deepen the flavor.
Serve: Run a thin knife around the edge, release the springform, and slice with a warm, clean knife. Add fresh berries or a light topping if you like.
