Keto Rhubarb Cheesecake (Printable version)

Creamy low-carb cheesecake with tangy rhubarb swirl and buttery almond crust. Just 5g carbs per slice.

# What you need:

→ Almond Flour Crust

01 - 1 1/2 cups almond flour
02 - 1/4 cup powdered erythritol
03 - 1/4 cup unsalted butter, melted
04 - 1/2 teaspoon ground cinnamon
05 - Pinch of salt

→ Rhubarb Compote

06 - 1 1/2 cups fresh rhubarb, chopped
07 - 1/4 cup powdered erythritol
08 - 1 teaspoon fresh lemon juice
09 - 1 teaspoon water

→ Cream Cheese Filling

10 - 24 oz cream cheese (3 packages), softened to room temperature
11 - 3/4 cup powdered erythritol
12 - 1/2 cup sour cream
13 - 3 large eggs
14 - 1 teaspoon pure vanilla extract
15 - Zest of 1 lemon

# How To:

01 - Preheat oven to 325°F. Line the bottom of a 9-inch springform pan with parchment paper and lightly grease the sides.
02 - In a mixing bowl, combine almond flour, erythritol, melted butter, cinnamon, and salt. Stir until a crumbly dough forms. Press the mixture firmly and evenly into the bottom of the prepared pan. Bake for 10 minutes, then remove and set aside to cool completely.
03 - Combine rhubarb, erythritol, lemon juice, and water in a small saucepan. Cook over medium heat, stirring frequently, until the rhubarb breaks down and the mixture reaches a jam-like consistency, about 8 minutes. Remove from heat and let cool.
04 - Using an electric mixer, beat the softened cream cheese and erythritol together on medium speed until completely smooth and free of lumps. Add sour cream, then incorporate the eggs one at a time, mixing briefly after each addition. Blend in the vanilla extract and lemon zest. Stop mixing as soon as everything is combined to avoid incorporating excess air.
05 - Pour the cream cheese filling over the cooled crust, spreading it into an even layer. Drop small spoonfuls of the rhubarb compote across the surface. Using a butter knife or offset spatula, gently drag through the compote dollops to create decorative swirls throughout the batter.
06 - Tap the springform pan firmly on the counter a few times to release trapped air bubbles. Place in the oven and bake for 45 to 50 minutes, until the edges are set and the center retains a slight jiggle. Turn off the oven, crack the door open, and allow the cheesecake to cool gradually inside for 1 hour.
07 - Transfer the cheesecake to the refrigerator and chill for a minimum of 2 hours, or until fully set and firm to the touch. Slice with a sharp knife dipped in hot water for clean portions.

# Expert Advice:

01 -
  • The tangy rhubarb swirl cuts through the richness of the cream cheese so perfectly that nobody will guess it is sugar free.
  • Only five net carbs per slice means you can have seconds without a single pang of guilt.
02 -
  • Overmixing the filling whips too much air into the batter, which causes ugly cracks and a puffy, fallen texture.
  • The slow cool down inside the oven is not optional if you want a smooth, flat top.
03 -
  • Take the cream cheese out of the refrigerator at least two hours before you start, because cold cheese will leave lumps no amount of mixing can fix.
  • Line the sides of the pan with a collar of parchment paper for an insurance policy against sticking and cracking.
