Preheat your oven to 325°F (163°C). Line an 8x8 inch pan with parchment paper.
In a bowl, mix almond flour, granulated erythritol, and melted butter. Press the mix firmly into the pan to form a crust.
Bake the crust for 10 minutes, then let it cool slightly.
Meanwhile, beat cream cheese until smooth. Add powdered erythritol, eggs, vanilla, and sour cream. Mix until fully combined.
Pour the cheesecake mixture over the crust and smooth the top.
Gently swirl in chopped strawberries across the surface.
Bake for 30–35 minutes or until the center is just set and the edges look a bit puffed.
Cool completely at room temperature, then chill for at least 2 hours before slicing.
