  1. If using cream cheese glaze, Mix 2 Tbsp (1 oz) of cream cheese, 1 Tbsp of butter, 8 Tbsp powdered sweetener, 1/2 teaspoon of vanilla extract together. Thin it out with water to your desired consistency.
  2. If you notice the bread is browning at the top too quickly, cover the top of the pan with foil to prevent it from getting overcooked with the center being undercooked.
  3. The bread is ready when a cake tester or small knife inserted at the center comes out clean.
  4. Butter flavored coconut oil can be substituted for butter in this recipe
