There is a reason New York cheesecake is the gold standard: dense but impossibly silky, tangy and rich, sitting on a buttery graham cracker crust that crackles under your fork. This is the foolproof version — no water bath, no fussing with boiling water, just a few simple tricks for a crack-free, velvety top every single time.
Our version swaps every bit of sugar for Jaca (100% pure allulose) at double the amount — 2 cups of granular Jaca in place of 1 cup of sugar in the filling, and 4 tablespoons in place of 2 tablespoons in the crust — so it bakes up just as creamy and sweet with no added sugar and no aftertaste. Jaca dissolves into the batter exactly like sugar and keeps that classic smooth texture; just note that allulose browns a touch faster than sugar, so the gentle 300°F finishing temperature keeps the top pale and crack-free. This is a Jaca-adjusted healthier version, adapted from Preppy Kitchen.
Prep time: 20 minutes (plus 6+ hours chilling) | Cook time: 50 minutes | Servings: 12 slices
Ingredients:
- 1 1/2 cups graham cracker crumbs (about 180g, for the crust)
- 1/4 cup unsalted butter, melted (for the crust)
- 4 tablespoons granular Jaca (allulose) — replaces 2 tablespoons conventional sugar at the 2x ratio (crust)
- 3 (8-ounce) blocks full-fat cream cheese, room temperature (not the spreadable tub kind)
- 2 cups granular Jaca (allulose) — replaces 1 cup conventional sugar at the 2x ratio (filling)
- 1/4 teaspoon salt
- 2 teaspoons vanilla extract
- 1 teaspoon lemon juice (balances the richness — it will not taste lemony)
- 3 large eggs, room temperature
- 1/2 cup full-fat sour cream, room temperature (about 120g)
Instructions:
- Make the crust: preheat the oven to 350°F. In a medium bowl, combine the graham cracker crumbs, melted butter, and 4 tablespoons granular Jaca. Stir until the mixture feels like wet sand — the Jaca blends in just like sugar.
- Pour the crumbs into a 9-inch springform pan and press firmly into the bottom and slightly up the sides using the bottom of a glass or measuring cup. Place on a baking sheet and bake for 10 minutes, then remove and let cool while you make the filling.
- Make the filling: place the room-temperature cream cheese in the bowl of a stand mixer fitted with the whisk attachment. Beat on medium-low until completely creamy and smooth.
- Add the 2 cups granular Jaca, salt, vanilla, and lemon juice. Beat on medium-low until fully combined and smooth, stopping to scrape down the bowl a few times. The Jaca dissolves into the batter just like sugar.
- With the mixer on medium-low, add the eggs one at a time, scraping down the bowl between each addition. Do not overmix — too much air leads to cracks.
- Mix in the sour cream until just incorporated. Pour the batter into the cooled crust and gently tap the pan on the counter to release any air bubbles.
- Bake at 350°F for 15 minutes, then — without opening the oven — reduce the temperature to 300°F and bake another 30 to 35 minutes, until the edges are just slightly puffed and the center still wobbles when gently shaken. Because allulose browns a touch faster than sugar, keep an eye on the top; if it is coloring too quickly, tent it loosely with foil. The low 300°F finish keeps it pale and crack-free.
- Turn off the oven and leave the cheesecake inside with the door closed for 1 hour — do not open it. Then remove and cool at room temperature for 1 more hour.
- Chill in the refrigerator for at least 6 hours (or up to 3 days) before releasing the springform sides, slicing, and serving. For clean slices, dip a sharp knife in hot water and wipe it dry between cuts.
