Keto Rhubarb Cheesecake (Printable)

Creamy low-carb cheesecake with tangy rhubarb swirl, perfect for keto diets.

# What You Need:

→ Almond Flour Crust

01 - 1½ cups almond flour
02 - ¼ cup powdered erythritol
03 - ¼ cup unsalted butter, melted
04 - ½ teaspoon ground cinnamon
05 - Pinch of salt

→ Rhubarb Compote

06 - 1½ cups fresh rhubarb, chopped
07 - ¼ cup powdered erythritol
08 - 1 teaspoon fresh lemon juice
09 - 1 teaspoon water

→ Cream Cheese Filling

10 - 24 ounces cream cheese (3 packages), softened to room temperature
11 - ¾ cup powdered erythritol
12 - ½ 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, evenly moistened 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 - In a small saucepan, combine chopped rhubarb, erythritol, lemon juice, and water. Cook over medium heat, stirring frequently, until the rhubarb breaks down and the mixture thickens to a jam-like consistency, about 8 minutes. Remove from heat and let cool.
04 - In a large bowl, beat the softened cream cheese and erythritol with an electric mixer until completely smooth and free of lumps. Add sour cream and blend briefly. Add eggs one at a time, mixing on low speed after each addition until just incorporated. Stir in vanilla extract and lemon zest. Do not overmix to avoid incorporating excess air.
05 - Pour the cream cheese filling over the cooled crust, spreading evenly. Drop small spoonfuls of the cooled rhubarb compote across the surface. Using a butter knife or skewer, gently drag through the compote dollops to create decorative swirls throughout the filling.
06 - Tap the springform pan firmly on the counter a few times to release trapped air bubbles. Place in the center of the oven and bake for 45 to 50 minutes, until the edges are set and the center still has a slight jiggle. Turn off the oven, crack the door open, and let the cheesecake rest inside for 1 hour to cool gradually and prevent cracking.
07 - Remove the cheesecake from the oven and let it come to room temperature. Transfer to the refrigerator and chill for at least 2 hours, or until fully set. Slice into 12 even portions and serve chilled.

# Expert Tips:

01 -
  • The rhubarb compote cuts through the richness of the cream cheese in a way that feels almost magical, like the two were always meant to find each other.
  • Using almond flour for the crust instead of graham crackers means you stay low carb without sacrificing that satisfying crunch beneath the filling.
  • It looks like something from a bakery window but comes together with basic tools and a little patience.
02 -
  • Overmixing the filling after adding eggs is the fastest way to get cracks, so stop mixing the moment everything looks uniform.
  • The cheesecake will look slightly underdone in the center when you take it out, and that is exactly right because it continues to cook as it rests.
  • Cooling inside the oven with the door cracked prevents the sudden temperature drop that causes surface splitting.
03 -
  • Set your cream cheese on the counter at least two hours before starting, because patience at that step saves you from a lumpy filling no amount of mixing can fix.
  • A touch of freshly grated ginger added to the rhubarb compote transforms the flavor into something unexpectedly complex without adding any carbs.
