Recipe Equipment
You only need a few basic kitchen tools to make this creamy cheesecake:
- 9-inch springform pan – makes removing the cheesecake easy.
- Food processor – ideal for creating a fine chocolate-almond crust.
- Large mixing bowl – for preparing the cheesecake filling.

- Rubber spatula – perfect for scraping the bowl and smoothing the cheesecake.

- Small microwave-safe bowl – for melting the chocolate topping.
Ingredients
For the Chocolate Crust
- 1 1/2 cups almond flour
- 3 tablespoons unsweetened cocoa powder
- 3 tablespoons powdered monk fruit or erythritol
- 5 tablespoons unsalted butter, melted
- 1/2 teaspoon vanilla extract
- Pinch of salt
For the Peanut Butter Cheesecake Filling
- 16 ounces full-fat cream cheese, softened
- 3/4 cup natural creamy peanut butter, unsweetened
- 1/2 cup powdered keto-friendly sweetener
- 1 teaspoon vanilla extract
- 1/2 cup heavy whipping cream
- 2 large eggs
- 1/4 teaspoon salt
For the Chocolate Topping
- 3 ounces sugar-free dark chocolate
- 2 tablespoons heavy cream
- 1 tablespoon creamy peanut butter, optional
- Chopped sugar-free peanut butter cups, optional, for garnish
Ingredient Notes
Almond flour: This creates a tender, slightly nutty crust while keeping the recipe lower in carbohydrates than a traditional cookie crust.
Cream cheese: Use full-fat cream cheese at room temperature. Softened cream cheese blends much more easily and helps prevent lumps.
Peanut butter: Choose natural peanut butter without added sugar. Stir it well before measuring because the oils can separate.
Keto sweetener: Powdered sweetener blends smoothly into the filling. Granulated sweetener may leave a slightly grainy texture.
Sugar-free chocolate: Choose a keto-friendly chocolate with no added sugar. Dark chocolate gives the topping a rich flavor that pairs beautifully with peanut butter.
How to Make Keto Reese’s Peanut Butter Cup Cheesecake
1. Prepare the Chocolate Crust
Preheat your oven to 350°F and lightly grease a 9-inch springform pan.
In a bowl, combine almond flour, cocoa powder, powdered sweetener, and salt. Stir in the melted butter and vanilla until the mixture resembles moist crumbs.
Press the mixture firmly into the bottom of the pan, creating an even layer. Bake for about 8–10 minutes, then allow the crust to cool completely.
2. Make the Creamy Peanut Butter Filling
In a large bowl, beat the softened cream cheese until completely smooth and creamy.
Add the peanut butter, powdered sweetener, vanilla, and salt. Mix until everything is evenly incorporated and silky.
Pour in the heavy cream and mix again. Add the eggs one at a time, mixing gently after each addition. Avoid overmixing once the eggs are incorporated.
3. Fill and Bake
Pour the peanut butter cheesecake mixture over the cooled chocolate crust.
Smooth the top with a spatula so the cheesecake bakes evenly. Place the pan in the oven and bake at 325°F for approximately 45–55 minutes.
The edges should look set while the center still has a slight jiggle. Don’t worry if the middle looks a little soft—it will firm as the cheesecake cools.
4. Cool Slowly
Turn off the oven and leave the cheesecake inside with the door slightly open for about 20–30 minutes.
Remove it from the oven and let it cool completely at room temperature. This gradual cooling can help reduce cracking.
5. Add the Chocolate Topping
Melt the sugar-free chocolate and heavy cream together in short microwave intervals, stirring between each interval until smooth and glossy.
Spread the chocolate mixture over the cooled cheesecake. If desired, drizzle a little peanut butter over the top and swirl gently with a toothpick.
6. Chill Until Firm
Cover the cheesecake and refrigerate for at least 4–6 hours, preferably overnight.
Once thoroughly chilled, carefully release the springform pan and slice with a sharp knife. For especially clean slices, wipe the knife between cuts.
Serving Suggestions
Serve each slice chilled with a drizzle of melted peanut butter or a small dollop of unsweetened whipped cream.
For an extra chocolate-peanut-butter finish, sprinkle the top with chopped sugar-free chocolate or crushed keto-friendly peanut butter cups.
This cheesecake is rich, so smaller slices are often perfect. Pair it with coffee or unsweetened tea for a wonderful after-dinner treat.
Pro Tips & Variations
For the smoothest cheesecake, make sure your cream cheese and eggs are at room temperature before mixing. Use powdered sweetener for a silky filling. If you prefer a stronger chocolate flavor, add an extra tablespoon of unsweetened cocoa powder to the crust. You can also make individual mini cheesecakes using a muffin pan lined with cupcake liners. For extra peanut butter flavor, swirl two tablespoons of softened peanut butter into the filling before baking. Always chill thoroughly before slicing. If you want a no-bake variation, prepare the filling without eggs and refrigerate until completely firm.
Storage Information
Store leftover Keto Reese’s Peanut Butter Cup Cheesecake in an airtight container or tightly covered in the refrigerator for up to 5 days.
For longer storage, freeze individual slices for up to 2 months. Wrap each slice tightly and place it in a freezer-safe container.
Thaw frozen cheesecake overnight in the refrigerator. Avoid thawing it at room temperature for an extended period because the creamy filling can soften too much.
