Keto 90 Second Bread #keto #lowcarb

This coconut flour 90-second bread is keto and gluten-free. It has a lovely spongy texture that readily soaks up butter, sugar-free honey, or jam.

90-second bread is a keto and low carb microwave bread made with coconut flour. It is “baked” in the microwave in 90 seconds, hence its name.


  • 1 tablespoon unsalted butter (if using salted, omit the salt)
  • 1/4 teaspoon kosher salt (or just a pinch of fine salt)
  • 1 large egg
  • 1 tablespoon coconut flour
  • 1/4 teaspoon baking powder (gluten free if needed)


  1. In a small microwave safe bowl (mine measures 3 inches on the bottom and 3.5 inches at the top), melt the butter in the microwave.
  2. Allow the melted butter to slightly cool, then mix in the remaining ingredients until smooth.
  3. Microwave the mixture on high for 90 seconds. Bread will puff up while “baking,” then slightly deflate. When done, it will look like a muffin. Make sure it appears set, otherwise microwave 10-20 more seconds (but 90 seconds should be enough, and overcooking can dry it up). Take care when removing it from the microwave. The bowl will be hot.
  4. Let the bread slightly cool, a minute or so. Then gently, with a paring knife, loosen the bread edges and remove from the bowl onto a plate.
  5. Slice the 90 second bread crosswise into two slices and top with your favorite toppings.
  6. If you’d like to toast the 90-second bread, heat 1 tablespoon of unsalted butter in a medium skillet over medium-low (not higher) heat. Or spray the skillet with olive oil spray. Add the bread slices. Cook, gently pressing on them with a spatula to ensure even toasting, until golden, about 3 minutes per side.
