Preheat the oven: Preheat to 425°F. Grease or line a 7-inch springform pan with parchment. Place pan on a baking sheet.
Beat cream cheese and sweetener: Using an electric mixer, beat cream cheese and allulose until smooth. Add monk fruit extract to taste.
Add eggs: Add eggs one at a time, mixing until combined.
Mix in remaining ingredients: Add heavy cream, vanilla, salt, and almond flour. Mix until smooth. Tap bowl on counter to remove air bubbles.
Bake: Pour into prepared pan. Bake 35–45 minutes — less time for a creamier texture, more time for a firmer/fluffier texture.
Cool and chill: Let the cheesecake cool completely in the pan, then refrigerate uncovered for at least 4 hours or overnight.
Serve: Remove the sides of the springform, slice, and serve at room temperature or chilled. Enjoy!
Notes
Texture control: Bake 35 minutes for a softer, custard-like center; bake 45 minutes for a firmer, fluffier cheesecake.
Sweetener: Allulose is recommended for the best texture and caramelization on top.
Monk fruit extract: Liquid or powdered extract can be used. Mine is a powder that comes with a tiny scoop equivalent to about 1/16 tsp. If using liquid, a few drops will be perfect.
Flour: Almond flour can be replaced with regular flour, or omitted if needed.
Oven temperature: If your oven tends to run hot or cook things more quickly, you can feel free to set the oven temp to 400°F instead of 425°F.
Make ahead: Can be made a day in advance; flavor and texture improve after chilling overnight.
