Sugar-Free Classic Old-Fashioned Cheesecake

This is a classic baked cheesecake with an almond flour crust and a monk fruit–sweetened filling. Completely grain-free, low-carb, and designed to be sugar-free.

  • About 8 servings

Ingredients

For the grain-free crust:

  • 1 ½ cups blanched almond flour

  • 2 Tbsp monk fruit sweetener (granulated)

  • ¼ tsp ground cinnamon

  • ¼ cup unsalted butter, melted (plus a little extra for greasing the pan)

  • ½ tsp vanilla extract

For the sugar-free cheesecake filling:

  • 24 oz full-fat cream cheese, at room temperature

  • 1 cup monk fruit sweetener

  • 1 tsp vanilla extract

  • 3 large eggs, at room temperature

  • ½ cup full-fat sour cream, at room temperature

  • 1 Tbsp freshly squeezed lemon juice (room temperature)

Directions

  1. Bring ingredients to room temperature

    • About 45 minutes before baking, take out the cream cheese, eggs, sour cream, and lemon juice.

    • Cube the cream cheese and spread it on a plate so it warms evenly. Let everything sit until it no longer feels cold to the touch.

  2. Preheat and prep pan

    • Preheat oven to 350°F (175°C).

    • Grease a 9-inch non-stick springform pan with butter.

  3. Make the crust

    • In a medium bowl, whisk together almond flour, monk fruit sweetener, and cinnamon.

    • Stir in melted butter and vanilla extract until the mixture looks like damp sand.

    • Press this mixture evenly and firmly into the bottom of the springform pan.

    • Bake for about 10 minutes, until lightly golden and fragrant.

    • Remove and let the crust cool on a wire rack while you make the filling.

  4. Lower oven temperature

    • Reduce oven temp to 325°F (160°C).

  5. Make the filling

    • In a stand mixer (paddle attachment) or with a hand mixer, beat the softened cream cheese and monk fruit sweetener on medium until smooth and creamy, scraping the bowl as needed.

    • Turn the mixer to low, add vanilla extract.

    • Add the eggs one at a time, mixing on low just until each one is incorporated. Do not overmix.

    • Gently fold in sour cream and lemon juice with a spatula until the batter is smooth.

  6. Bake the cheesecake

    • Pour the filling over the cooled crust and smooth the top. Tap the pan gently on the counter a few times to release any air bubbles.

    • Place the springform pan on a baking sheet and bake 50–60 minutes, until the edges are set but the center still has a slight jiggle.

  7. Cool gradually

    • Turn off the oven and crack the door open slightly.

    • Let the cheesecake cool in the oven for about 1 hour to help prevent cracks.

  8. Chill

    • Transfer the pan to a wire rack and cool to room temperature.

    • Once cooled, refrigerate at least 4 hours, preferably overnight, until fully set.

  9. Slice and serve

    • Run a knife around the edge of the cheesecake before releasing the springform ring.

    • Slice into 8 pieces, wiping and warming the knife (dip in hot water, wipe dry) between cuts for clean slices.

    • Serve plain or topped with fresh berries or a sugar-free sauce.

  10. Storage

    • Refrigerate leftovers in an airtight container
