Ingredients Overview

Almond Flour Crust

This simple crust uses almond flour and butter to create a nutty, shortbread-like base. It’s crisp enough to hold the filling while remaining tender and keto-friendly.

Tip: Lightly toast the almond flour in a dry pan before mixing to deepen the flavor.

Cream Cheese

Use full-fat cream cheese for the creamiest texture. It should be room temperature to blend smoothly and avoid lumps.

Natural Peanut Butter

Choose a creamy, unsweetened peanut butter with just peanuts and salt. Stir well if it has separated.

Avoid peanut butter with added sugar or oils, which can affect texture and carb count.

Eggs

Eggs provide structure and help the cheesecake set properly. Use room-temperature eggs for best mixing.

Sweetener

Use a keto-approved sweetener like erythritol, monk fruit, or allulose. Powdered varieties blend best into cheesecake without grittiness.

Sour Cream or Heavy Cream

Adds moisture and smoothness. Sour cream lends a tangy note, while heavy cream gives a silkier finish.

Vanilla Extract

Boosts the flavor profile and brings warmth to both the crust and filling.

Step-by-Step Instructions

1. Preheat & Prepare the Pan

Preheat your oven to 325°F (163°C). Line the bottom of a 9-inch springform pan with parchment and grease the sides.

Wrap the outside with foil to prep for a water bath (optional, but helps prevent cracks).

2. Make the Crust

In a bowl, mix:

• 1½ cups almond flour

• 3 tbsp melted butter

• 2 tbsp powdered erythritol

• ½ tsp vanilla extract

Press firmly into the bottom of the pan. Bake for 10–12 minutes until golden and set. Let cool while preparing the filling.

3. Prepare the Cheesecake Filling

In a large bowl or stand mixer, beat:

• 24 oz (3 blocks) cream cheese, softened

• ¾ cup powdered sweetener

• ¾ cup natural creamy peanut butter

Mix until completely smooth.

Add:

• 3 large eggs, one at a time

• ½ cup sour cream (or heavy cream)

• 1½ tsp vanilla extract

Blend just until smooth and fully combined. Avoid overmixing to keep the texture creamy.

4. Bake

Pour the filling over the cooled crust. Smooth the top with a spatula.

Place the pan into a large roasting dish and pour in hot water to reach halfway up the sides (for a water bath).

Bake for 50–60 minutes, until the edges are set and the center has a slight jiggle.

Turn off the oven, crack the door, and let cool for 1 hour in the oven.

5. Chill

Remove from the oven and cool to room temperature. Then refrigerate for at least 4 hours, preferably overnight, to fully set.

Before serving, top with:
