Mini Cocoa Swirl Cheesecakes

1. Pre-heat oven to 350 °F (175 °C). Line 6 regular size muffin cups with paper foil liners. 2. Blend cream cheese and ricotta in a food processor until creamy. Add sugar substitute, egg, egg yoke, vanilla and process until smooth. 3. Divide 1 cup of batter among the 6 muffin cups. Add cocoa powder to the remaining batter and combine. Drop a heaping tablespoon of the cocoa batter into each muffin cup and gently fold to form a swirl. 4. Place the muffin tin in a large roasting pan and fill the pan with hot water to reach half way up the muffin tin. This is called a bain marie. 5. Bake until the cakes are puffed and set, 18-20 minutes. 6. Remove from the bain marie and cool at room temperature. 7. Refrigerate until chilled, about 2 hours. Bon Appetite! 8.
