Preheat your oven to 325°F (165°C) and line an 8x8 inch baking pan with parchment paper.
In a bowl, mix together the almond flour, coconut flour, and granulated sweetener until well combined.
Stir in the melted butter until the mixture is crumbly.
Press the mixture into the bottom of the prepared pan to form an even crust.
Bake the crust for 10-12 minutes, or until lightly golden brown.
In a separate bowl, beat the cream cheese and powdered sweetener together until smooth.
Add the eggs and vanilla extract, and beat again until well combined.
Fold in the chopped strawberries.
Pour the cheesecake mixture over the baked crust, and spread it evenly.
Bake the cheesecake for 25-30 minutes, or until the edges are set and the center is slightly jiggly.
Let the cheesecake cool to room temperature, and then chill in the refrigerator for at least 2 hours.
Cut the cheesecake into bars and serve chilled.
