Add the coconut flour, mozzarella, salt, xanthan gum, baking soda, and erythritol to a food processor. Pulse everything together well to combine. The mixture should form a chunky crumb consistency. You may swap the sweetener for your preferred low carb granulated or powdered sweetener, adjusting quantities to taste.
Add the cream cheese, butter, and lemon juice to the food processor. Blend together to combine. The crumb should now start to thicken and bind together.
Crack the egg into the food processor. Blend well with the other ingredients. A pliable dough should now have formed in the food processor jug.
Preheat the oven to 350 degrees Fahrenheit and line a shallow oven tray with baking paper. Divide the dough into four even portions and roll each portion into a ball. Arrange the dough balls side by side in a square formation on the lined oven tray. Press the dough balls down slightly with the palm of your hand to create a roll shape.
Mix together the melted butter and lakanto syrup. Brush the butter and syrup mixture liberally all over the bread rolls. You may use an alternative low carb sweetener if desired; however, a syrup will create the best glaze. You may also omit the sweetener if preferred and just glaze with butter.
Transfer the tray to the oven and bake for 25- 30 minutes or until completely cooked through. The rolls should be risen and golden brown all over. Set aside to cool and firm.
