Make 90-second bread according to the instructions here.
While the bread cools, whisk together the egg, heavy cream, cinnamon, vanilla, and 1 teaspoon Besti Powdered Monk Fruit Erythritol Blend in a small bowl.
Dip the cooled bread in the egg mixture, flipping to coat both sides.
In a frying pan over medium heat, melt the butter. Add the bread and cook 1-1.5 minutes, until golden brown. Flip and cook for 1-1.5 minutes again, until browned on the other side.
Sprinkle French toast with 1/2 teaspoon Besti Powdered Monk Fruit Erythritol Blend (or to taste). Top with keto maple syrup if desired.
