Ingredients
- 1/2 cup almond flour ((or equal parts almond flour, coconut flour, and ground golden flaxseed))
- 2 tbsp melted butter
- 20 oz cream cheese ((2 1/2 packs))
- 1/2 cup Joy Filled Eats Sweetener (or see alternatives in recipe notes) ()
- 1 tsp fresh lemon zest (adjust to taste for brightness)
- pinch salt
- 3 eggs
- 1/3 cup sour cream
- 1 tbsp Joy Filled Eats Sweetener (or see alternatives in recipe notes) ()
- berries (optional)
Instructions
- Preheat your oven to 350°F (175°C).
- To make the crust, combine the almond flour and melted butter in a small bowl. Press this mixture firmly into the bottom of a greased 8-inch springform pan.
- In a large mixing bowl, beat the cream cheese until smooth and creamy.
- Add the 1/2 cup of sweetener, fresh lemon zest (adjust to taste for brightness), and pinch of salt to the cream cheese. Beat until fully combined and smooth.
- Add the eggs one at a time, beating well after each addition until just incorporated. Avoid overmixing.
- Mix in the sour cream until the filling is uniform.
- Pour the cheesecake filling over the prepared crust in the springform pan.
- Place the pan on a baking sheet and bake for 45-50 minutes, or until the edges are set and the center is slightly jiggly.
- Remove the cheesecake from the oven and let it cool completely in the pan on a wire rack.
- Once cooled, run a knife around the edge of the pan before releasing the springform ring.
- In a small bowl, mix the remaining 1 tablespoon of sweetener with a few fresh berries (if using) and spoon over individual slices just before serving.
Variations
- For a more intense lemon flavor, add the zest of one lemon to the filling along with the fresh lemon zest (adjust to taste for brightness).
- Skip the crust for a crustless version and simply pour the filling into a well-greased pan.
- Create a swirled effect by gently folding a few tablespoons of sugar-free berry jam into the batter before baking.
- Serve with a dollop of lightly sweetened whipped cream instead of fresh berries.
Tips for Success
- Ensure all your ingredients, especially the cream cheese and eggs, are at room temperature for a smooth, lump-free filling.
- To prevent cracks, avoid opening the oven door during the first 40 minutes of baking.
- For clean slices, dip your knife in hot water and wipe it clean between each cut.
Storage & Reheating
Store the cheesecake covered in the refrigerator for up to 5 days. This dessert is best served cold and does not require reheating, but you can let individual slices sit at room temperature for 10-15 minutes before serving for a softer texture.
FAQ
Can I use a different sweetener?
Yes, the recipe notes mention alternatives. Use any granulated erythritol-based or monk fruit sweetener that measures like sugar in a 1:1 ratio.
My cheesecake cracked. What happened?
Cracking is often caused by overmixing (adding too much air), a sudden temperature change, or overbaking. Using a water bath can help prevent this, but the tips above also minimize the risk.
Can I make this without a springform pan?
Yes, you can use a regular 8-inch cake pan lined with parchment paper, but removing slices will be less elegant.
Is the crust necessary?
No, you can make a crustless cheesecake. The texture will be slightly denser and more like a New York-style cheesecake.
Can I freeze this cheesecake?
Absolutely. Wrap the cooled cheesecake (or individual slices) tightly in plastic wrap and then foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
What can I use instead of fresh lemon zest (adjust to taste for brightness)?
You can use the juice and zest of 1-2 fresh lemons. Use about 3 tablespoons of juice and all the zest for a vibrant, natural lemon flavor.
