Ingredients
For the Keto Chocolate Sponge:
Almond flour – 1/2 cup
Coconut flour (optional) – 1/4 cup
Unsweetened cocoa powder – 1/4 cup
Psyllium husk powder – 1 tbsp
Baking powder – 1 tsp
Erythritol or Swerve – 1/2 cup
Eggs – 6 large
Melted butter – 3 tbsp
Sour cream – 2 tbsp
Vanilla extract – 1 tsp
Pinch of salt
For the Cream Cheese Filling:
Cream cheese – 8 oz, softened
Butter – 4 tbsp, softened
Erythritol – 1/4 cup
Sour cream – 2 tbsp
Vanilla extract – 1 tsp
Optional Keto Ganache:
Sugar-free dark chocolate – 6 oz

Instructions
1. Preheat your oven to 350°F (180°C). Line a 10×15-inch pan with parchment paper.
2. Whisk almond flour, cocoa, baking powder, psyllium, and salt in a bowl.
3. In another bowl, beat eggs with erythritol until light and foamy (2–3 minutes).
4. Add melted butter, sour cream, and vanilla; mix until smooth.
5. Fold dry ingredients into wet mixture gently until just combined.
6. Spread evenly into the lined pan and bake 12–15 minutes or until springy.
7. Remove from oven, invert onto parchment, and roll up while warm to form the shape. Let cool.
8. For the filling, beat cream cheese, butter, erythritol, sour cream, and vanilla until smooth and creamy.
9. Unroll the cooled sponge, spread filling evenly, and re-roll tightly.
10. Chill for at least 1 hour for clean slices. Optionally top with keto ganache or powdered erythritol before serving.
Notes
Roll the sponge while still warm for flexibility.
Do not overbake — a dry sponge cracks easily.
Chill before slicing for neat layers.
Use powdered erythritol for a smooth, creamy filling.
