Heat the butter in a medium skillet over medium heat.
Whisk the egg, heavy cream, almond milk, vanilla extract, and half of the cinnamon together in a bowl.
In a separate bowl, combine the erythritol and the other half of the cinnamon.
Warm the bread in the microwave for 5-10 seconds.
Note: This is just enough to make the bread slightly warm so it will absorb the liquid better.
Dip the bread in the egg yolk mixture.
Note: If you like a more eggy taste, leave the bread in longer.
Place the toast into the pan and cook for 1-2 minutes on each side, or until golden brown.
As soon as you remove the toast from the pan, sprinkle the cinnamon and sugar mixture on top.
Note: You can also place this mixture in a Ziploc bag, place the toast in side, and shake to cover it.
Optional: Try topping with fresh berries, nut butter, sugar-free syrup, chocolate chips, or whipped cream for a more decadent keto french toast.
