Preheat oven to 350 degrees Fahrenheit. Spray a 9” circular pan with coconut oil or grease with butter. Have two 15 inch sheets of parchment and a rolling pin handy.
Prepare a double boiler. A medium saucepan with a medium bowl that will sit on top works fine for this purpose. Add about 2 inches of water to the saucepan or lower part of the double boiler. Place over high heat and bring to a simmer uncovered. Once simmering, reduce heat to low.
Meanwhile in the top-part of the double boiler (with it not over the water) combine the almond flour, stevia/erythritol sweetener, xanthan gum, and baking powder using a whisk.
Stir in the egg and vanilla extract. The mixture will be very thick.
Stir in the mozzarella cheese and place the bowl over the pot of simmering water. Be sure to protect your hands from the hot bowl and the steam escaping the pot. A silicone mitten works well for this purpose.
Stir the mixture constantly while the cheese melts and combines with the flour. It will begin to look like bread dough.
When the cheese has melted completely, transfer the dough to a prepared piece of parchment. Knead the dough a few times to completely combine the flour mixture and the cheese. Pat dough into a rectangular shape and cover with the second piece of parchment. Roll out dough into about 12" X 15" rectangle. Remove top parchment.
Evenly spread the lemon cream cheese filling on the dough, leaving about ½ inch uncovered on the edges. Spread the raspberry sauce over the lemon cream cheese filling.
Starting at the long side, roll the dough into a log shape. Press the outside long edge to seal.
Using a serrated knife, gently cut the log crosswise into 8 pieces. Arrange rolls in the prepared pan with one roll in the center and the rest circled around it.
Bake for 24-26 minutes, or until golden brown.
