4.7 Stars (19 Reviews) 45 Comments

The best airy, fluffy keto bread that looks and tastes like bread - all without that eggy flavor typical of most keto bread recipes. Just 90 seconds to bake and you see what this recipe is better than sliced bread.

Being able to make gluten-free keto bread in minutes is key to sticking to the low carb lifestyle. In fact, having access to easy portion-controlled recipes are ideal for when cravings hit, like these keto hostess cupcakes, which makes 2 cupcakes, or this sugar free chocolate mug cake.

If you have tried other recipes for 90 second keto bread before, you may have been disappointed. Most recipes for this quick bread fall flat because they have an overwhelming eggy flavor, taste like baking powder, have a strange yellow appearance or don’t taste like bread at all.

I tested many variations and came up with a recipe that looks like real sandwich bread. This 90 second bread made with almond flour is a fluffy low carb version of white bread with air holes through out to make it spongy and ready to soak up butter or mayonnaise. In fact it’s perfect for making sandwiches like grilled cheese. We disguise the eggy flavor thanks to a key ingredient. With instructions for baking bread in the microwave or oven, you simply can’t beat this recipe.

The best part is that this keto sliced bread toasts in a toaster to give you that perfectly golden brown crust and crunchy texture! Now you can have a side of toast with your eggs and bacon.


How to make 90 second keto bread

  1. Mix together the dry ingredients. Add almond flour, protein powder, baking powder, allulose and salt (if using) and mix until combined.
  2. Mix in wet ingredients. Add softened butter, egg white, sour cream and heavy cream.
  3. Bake in the microwave or oven. Pour into baking dish. Use a microwave or oven-safe baking dish lined with parchment paper. Bake for 90 seconds in the microwave or 9 minutes in the oven.
  4. Slice and serve. After cooling, slice down the middle to make 2 slices.

Key Ingredients

  • Almond flour – I use almond flour in the majority of keto baking as it is easily accessible to most in the grocery store or online. If you have a nut allergy, you can substitute with sunflower seed flour. It measures cup for cup with almond flour.
  • Protein powder – Protein powder is added to keto breads and baked goods to help puff them up and give them a fluffy texture without the need for additional eggs. The protein powder I use is a zero carb whey protein powder. You can substitute with any type of protein powder for this recipe.
  • Baking powder – The baking powder acts as an leavening agent to help the bread rise but it also contributes to flavor and browning effect when you toast or cook the bread in a griddle. It’s the key ingredient to give this low carb bread that perfect golden brown crust and crunch.
  • Allulose – An optional ingredient, a small amount of sweetener is added just for a touch of sweetness.
  • Salt – This is also an optional ingredient. You may want to omit this if you are making grilled cheese sandwiches as the cheese provides enough salt.
  • Butter – We use softened unsalted butter in this recipe to add fat, flavor and moisture. Many 90 second keto bread recipes can be dry. Butter helps to off-set this.
  • Egg white – The egg in keto bread helps to make the bread rise and provides structure and support. You could you an whole egg instead but it will change the color of your bread from white bread to yellow bread. If you do use a whole egg, omit the heavy cream.
  • Sour cream – This is my secret ingredient in keto baking to mask over any eggy flavor that eggs give off in a recipe. You could substitute with a low carb Greek yogurt – possibly cream cheese, although I haven’t experimented with this.
  • Heavy cream – Add for an extra bit of moisture so our bread isn’t dry. You can substitute with nut milk if needed.


Equipment needed

  • Square baking dish – The baking dish I used is both microwave safe and oven safe. It is square and came in a meal prep set similar to this set. The dish I used holds 781 ml.
  • Parchment paper – This will keep the bread from sticking to the sides of the baking dish. It also makes it easier to lift our your bread loaf.

How to use 90 second keto bread

There are many ways that you can use your easy keto bread. Here are some of my favorites:

  • Sandwiches – Since this recipe makes 2 slices of bread, you can easily make any sandwich you desire. Think of grilled cheese, turkey, ham, even a BLT! Just add mayo and your favorite sandwich fillings.
  • Spread – You can now easily enjoy bread and butter on the keto diet, especially if you are someone that must have bread with their dinner. Add your favorite spread – whether that is grass-fed butter, sugar-free jam, peanut butter or nut butter. Maybe even a little bit of cream cheese with Everything But the Bagel Seasoning.
  • Toast – My favorite way to enjoy 90 second bread is to toast it. This recipe crisps perfectly to a golden brown appearance and texture. It has the most unbelievable crunch when you bite down. I guess that means that avocado toast is back on the menu!
  • Breakfast – My go-to breakfast is over easy eggs on top of toast. Enjoy the classic breakfast of eggs, bacon and toast.

Storage instructions

If you find that you don’t eat all of your microwave keto bread and want to save the other slice or you want to meal prep keto bread, it is easy to store. Store your leftover bread in the refrigerator in an air tight container or bag for up to 5 days.

You can freeze it as well. Flash freeze your bread on a plate. Then store in a freezer safe bag with pieces of parchment paper placed in between each to keep them from freeze together. To thaw, leave at room temperature or in the refrigerator.

    1. I have experimented without it because I knew I wanted to use it for it’s baking properties, but you can try omitting it. It may change the texture of the bread.

        1. Hi Stephanie! I haven’t tried that substitution. I think you could get away with not using the protein powder…maybe even adding in a little more almond flour. The protein powder is there just for texture.

  1. Oh my goodness!!! This is such a good and versitile recipe. I realized last minute that I was out of sour cream so I subbed ricotta cheese instead and topped with everything but the bagel seasoning before microwaving. This was so stinking good. It didn’t even need butter on top and I couldn’t stop eating it warm right out of the microwave. Thank you Annie!

  2. Totally a winner !!! Taste is amazing, i doubled the salt because I like my bread salty and no sweet allulose for me. It toasts beautifully, I baked it for 11 minutes then let it cool and then toasted it. I made an amazing sandwich with mayo, lettuce, avocado, and tomato.

  3. This recipe is life changing! I am gluten free as well as a keto follower. This is so delicious and the texture and flavor make it perfect for grilled cheese.
    Thanks for sharing!

  4. Oh My God!!!!! is right… so so good and dangerous. I never would have thought we could make something like this in the microwave.

  5. This has changed my life ! Followed the recipe to a T and the results are outstanding. Dare I say I prefer this over regular bread . Most keto recipes I find are very labour intensive but whipped this up in less than 5 minutes on my lunch break .
    Wish there were instructions for making a whole loaf. I get that you could triple or quadruple the recipe however I can see how one wrong step can alter the texture ⭐️⭐️⭐️⭐️⭐️

  6. This so delicious! I know this is supposed to a quick one serving, but I’d love to be able to make a loaf of this. Do you have a recipe for a loaf? Thanks!

    1. I haven’t tried a whole loaf yet. I did double the recipe, which worked. It was pretty moist, so I recommend cooling it before cutting.

  7. I can’t wait to try this. I was wondering though, because I prefer to batch cook some things, can this recipe be increased & baked on a sheet pan rather like a flat bread, then sliced into servings? If I were to attempt this, what temperature would you recommend for the oven & would you suggest regular oven or convection? Thank you for the recipe!

    1. Baking it in a sheet pan is a good idea! I haven’t tried that but I think it would work if you wanted to make a larger batch

  8. Did not rise enough to slice successfully for me. I will try doubling the recipe next time. Only sub. I made was stevia instead of alluose and I used a whole egg- I don’t care about color or eggy taste. Quite sweet, it had a hint of almond cookie. I’m loving the Keto lifestyle!

  9. Hi… I made this bread earlier today. I baked at 350 degrees in a glass baking dish (3 and 3/4 inch by 3 and 3/4 inch). It took more than 20 minutes to bake. I think adding 1/3 cup almond flour would have given it a thicker consistency. I used protein powder with a blend of fermented pea protein, goji berry and hemp seed protein. I do not use whey protein because it raises insulin levels and is not good for Keto. The bread came out good and I enjoyed it toasted. Thank you.

  10. I love this! I’vebeen experimenting…I added a whole egg, just easier, and split the batter into two 5 or so inch ramekins. 9 min in the air fryer. I might try some milk kefir instead of the sour cream, since I don’t always have sour cream on hand. This recipe is a winner!!!

  11. This was SO tasty – came across it on Instagram and made it the next day, but the bottom of the bread came out wet on the parchment. Have you come across this and how did you solve it? Was every bit as spongy as described, went right in the toaster (which helped) and was the first time I’ve had avocado toast in a while. YUMMO!

    1. To use it as a sandwich bread, you do have to let it cool. It’s hard to use right away because it will be so moist.

  12. The toasty looks great. First came across this “bread” on Ketoserts some time ago. It’s a game changer for sandwiches.

  13. I have made this 4 times, each time using a large bottom cereal bowl, so it makes a thicker round result. It is wonderful. I cook it in my toaster oven, once it sliced in half. I made it today, and I choose to make French toast. It was wonderful! Very filling as well, probably from more protein in the egg mislxture to make it. I’m so glad that I watched your video. Thanks alot. It truly is a great bread. Now, what can I do with all my egg yokes🤔. More research…

  14. This is, hands down, my FAVORITE keto recipe so far. I really liked it when I took that first bite, but omygoodness…after I toasted it? Amazing! Thank you!

  15. I have unflavored Vital Proteins collagen powder Do you think could use that in place of the whey protein you used?

  16. This! This right here is the best Keto bread we have ever tried! I made it exactly like the recipe is written.. You really need to let it cool completely or you won’t be able to slice it very well. But if you can’t wait, just put the pieces in a buttered skillet and toast it that way. The texture did not make you think *Keto* it felt like regular bread.
    I’m ready to start exploring other options! Add the vanilla protein powder and cinnamon..cinnamon bread! Garlic and cheddar in a different shape? Garlic biscuits for your fish night!
    THANK YOU THANK YOU for such an awesome recipe!

  17. Hi, wondering if I can use collagen or gelatin powder? I don’t normally use whey. Also, wondering if that will work in the corn chip recipe 🙂 thanks

    1. I haven’t tried it with the collagen powder. It would probably be fine with the bread recipe but not sure how it would work with the chips.

  18. Just stumbled across this recipe. Outstanding! I tried 6 or more with the egg white only. Decided on the next 2, to use the whole egg. Other than the yellow color, it tasted every bit as good. I agree, now how to make a loaf of this? Thanks alot🍞
