This No-Bake Keto Cheesecake is a magnificent triumph of low-carb dessert alchemy, delivering all the rich, creamy indulgence of a classic New York-style cheesecake without a single gram of sugar or traditional flour. The recipe masterfully constructs a decadent dessert in layers, beginning with an innovative crust of crushed keto-friendly cookies and roasted pecans bound with butter, which bakes in the freezer to a firm, crumbly, and deeply nutty base. The true showpiece is the filling—a cloud-like, impossibly smooth marriage of whipped heavy cream and full-fat cream cheese, sweetened with confectioners’ monk fruit and brightened with a touch of lemon juice and vanilla. By whipping the cream separately to stiff peaks before gently folding it into the sweetened cream cheese mixture, the recipe ensures an ethereally light, mousse-like texture that sets firm yet melts luxuriously on the tongue.
The brilliance of this cheesecake lies in its flawless technique and the patient alchemy of chilling. The extended set time—a full 12 hours or overnight—is non-negotiable, allowing the flavors to marry and the structure to solidify into a sliceable, creamy perfection. This makes it an ideal make-ahead masterpiece for entertaining, completely eliminating day-of stress. It is a dessert that feels profoundly celebratory and indulgent, yet aligns perfectly with a ketogenic lifestyle, proving that dietary discipline never has to mean sacrificing the profound joy of a perfect slice of cheesecake. Every element, from the salty-sweet crust to the bright, creamy filling, is designed for maximum satisfaction, making it a guaranteed crowd-pleaser for any occasion, regardless of dietary preferences.

Ingredients:
For the No-Bake Crust:
1 ½ cups (about 150g) Highkey Mini Chocolate Chip Cookies (or any sugar-free, keto-friendly shortbread-style cookie)
1 cup (about 100g) roasted pecans
4 tablespoons (½ stick / 57g) unsalted butter, melted
For the Cheesecake Filling:
1 ½ cups (360ml) cold heavy whipping cream
2 (8-ounce / 226g) packages full-fat cream cheese, fully softened to room temperature
1 cup (120g) confectioners-style monk fruit sweetener (see tip)
¼ cup (60g) full-fat sour cream, at room temperature
2 teaspoons fresh lemon juice
2 teaspoons pure vanilla extract
Pinch of fine sea salt
Instructions:
Step 1: Prepare the Springform Pan
Lightly grease the bottom and sides of a 9-inch springform pan. Line the bottom with a circle of parchment paper for guaranteed easy release.
Step 2: Make the Crust
In a food processor, pulse the keto cookies and roasted pecans until they resemble fine crumbs. Drizzle in the melted butter and pulse until the mixture is evenly moistened and holds together when pinched. Transfer the mixture to the prepared pan. Using the bottom of a glass or a measuring cup, press it very firmly and evenly into the base to form a compact crust. Place the pan in the freezer to set while you make the filling.
Step 3: Whip the Heavy Cream
In a large, chilled metal or glass bowl, using a hand mixer or stand mixer with the whisk attachment, beat the cold heavy whipping cream on medium-high speed until stiff, firm peaks form. This takes 4-5 minutes. Do not over-whip. Immediately place the bowl of whipped cream in the refrigerator.
Step 4: Make the Cream Cheese Base
In another large bowl, beat the softened cream cheese with an electric mixer on medium speed until completely smooth and lump-free, about 2 minutes. Add the confectioners monk fruit, sour cream, lemon juice, vanilla extract, and salt. Beat again on medium speed until the mixture is perfectly smooth, creamy, and well combined, scraping down the sides as needed.
Step 5: Fold and Combine
Retrieve the bowl of whipped cream from the refrigerator. Using a large flexible spatula, gently fold about one-third of the whipped cream into the cream cheese mixture to lighten it. Then, carefully fold in the remaining whipped cream until no white streaks remain and the mixture is homogenous. Be gentle to maintain as much air as possible.
Step 6: Assemble and Chill
Remove the crust from the freezer. Spoon the cheesecake filling over the crust and smooth the top into an even layer with an offset spatula.
Cover the pan tightly with plastic wrap. Refrigerate for a minimum of 12 hours, and ideally 24 hours, to allow the cheesecake to set fully.
Step 7: Serve
To serve, carefully run a thin knife around the edge of the pan before releasing the springform collar. Slice with a clean, hot knife (dipped in hot water and wiped dry) for neat slices. Garnish with fresh berries, a dollop of whipped cream, or a drizzle of sugar-free chocolate sauce if desired.
Tips:
- Room Temperature is Critical: The cream cheese and sour cream must be fully softened to blend smoothly without lumps.
- Sweetener Note: Confectioners-style monk fruit (powdered/icing style) blends seamlessly. Granular sweeteners may create a gritty texture.
- Chill Your Bowl & Beaters: For best results when whipping the cream, chill your mixing bowl and beaters in the freezer for 15 minutes beforehand.
- Don’t Rush the Chill: The long, undisturbed chilling time is what gives this cheesecake its perfect, sliceable texture. Patience is rewarded.
- Crust Variations: You can use all nuts (like 2 ½ cups of almonds or pecans) or all keto cookies for the crust based on preference.
Storage Options:
- Refrigerator: Store covered in the springform pan or in an airtight container in the refrigerator for up to 5 days.
- Freezing: This cheesecake freezes exceptionally well. Wrap the whole cheesecake or individual slices tightly in plastic wrap, then in foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
- Make-Ahead: This is the quintessential make-ahead dessert. Prepare it 1-2 days before you need it for the best flavor and texture.
This No-Bake Keto Cheesecake is a celebration of smart, satisfying baking. It proves that with the right techniques and ingredients, you can create a spectacular, indulgent dessert that fits your lifestyle perfectly, offering a slice of pure, creamy joy with no compromise.
