Keto French Toast Chaffle Sandwich

Here’s how you make the chaffles.


  • 6 eggs
  • 1 T cinnamon
  • ½ c almond flour
  • ½ c powdered erythritol
  • 2 t baking powder
  • 1 t vanilla extract
  • 3 c shredded mozzarella cheese


  1. Preheat waffle iron according to manufacturer instructions.
  2. In a medium bowl, beat eggs.  Then add almond flour, erythritol, cinnamon, vanilla, and baking powder.  Stir until combined. Add the mozzarella cheese and stir until thoroughly mixed.
  3. Spray waffle iron with non-stick cooking spray (if desired).  Use a measuring cup to place a scant ¼ cup of batter into each section of a 4-slice waffle maker and cook to desired doneness.

Notes: This recipe makes approximately 12 mini waffles in my Bella four-slice waffle maker.  I make them in batches and then refrigerate them to use for sandwich building throughout the week.  Rumor has it that they can be frozen as well, but they don’t last that long at my house.

To make the breakfast sandwiches, I cook eggs in silicone egg rings.  I add shredded cheese to the eggs as they cook so I don’t have to fuss with cheese slices, although that’s a matter of personal preference.

While the eggs are cooking, I heat pre-cooked sausage patties in the microwave.

To build the sandwiches, I put a chaffle on a microwave-safe plate, and I drizzle it with sugar free Davinci Gourmet pancake syrup.  Then I add the cheesy egg, a sausage patty, and a second chaffle.  I pop the sandwich in the microwave for about 30 seconds to heat everything through, and that’s all there is to it!

This coming week, I’m going to try batch-cooking the eggs as well so I can assemble sandwiches ahead of time.  That way, I can heat a batch of sandwiches in the air fryer and I’ll be a little more efficient at getting folks out the door.  I don’t mind cooking for them, but I could definitely be more efficient on school mornings.
