I’m so excited to show you this high protein bread recipe — I tested it nearly a dozen times! Not only is it is packed with protein, it also just so happens to be low carb, it needs no flour of any kind, and it’s just as soft and fluffy as a store-bought white bread or whole wheat bread. This flourless bread is a great choice if you want to freshen up your healthy eating — or if you get tired of protein shakes, baked chicken breasts, and Greek yogurt all the time.
When I made flourless waffles years ago, I discovered that combining eggs and almond butter creates a texture that is surprisingly bread-like! So, I tested out the same concept in a grain-free bread loaf. It wasn’t enough structure on its own and my first few attempts collapsed, but when I experimented with adding protein powder, I finally achieved a tall, airy loaf with the perfect amount of chewiness.
While flourless bread recipes are often favored by people who are gluten-free or following a low carb diet, this protein bread is also a great healthier alternative to traditional bread — even if your daily diet doesn’t have any restrictions.

Ingredients & Substitutions
This section explains how to choose the best ingredients for bread with high protein, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.
- Whey Protein Isolate – Whey powder is what makes this a protein-rich bread. In fact, it’s packed with 25 grams of protein. This is also the most critical ingredient, because it provides the structure for this bread (similar to how wheat protein provides structure in wheat bread), which allows it to be tall and airy. I recommend this brand of whey protein isolate, which has no sugar or fillers. Keep in mind that cheaper brands of whey protein powder are typically whey protein concentrate, which is different and higher in carbohydrates, but might still work from a recipe standpoint. I tested the recipe with egg white protein powder and collagen, and both failed, but am not sure if other types of protein powder (such as pea protein) would yield good results or not.
- Eggs – You will need both egg whites and whole eggs for this bread. The egg whites provide structure as well and the yolks act as a leavener, so that the bread is soft and fluffy. Unfortunately, flax eggs or other egg substitutes will not work here.
- Almond Butter – Use unsweetened, salted, creamy almond butter. You could also use peanut butter, sunflower butter, or other nut butters. If your nut butter is unsalted, you’ll want to add a little bit of salt to the batter.
- Baking Powder – Helps the bread rise.
VARIATION: Add nuts or seeds!
These protein-rich ingredients add a nutty flavor and texture, and they would also boost the protein content of your bread even more. Try sunflower seeds, sesame seeds, flax seeds, or chopped pecans. Just fold them into the dough after blending.

How To Make Protein Bread
This section shows how to make flourless bread , with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.
- Prep. Preheat oven Line a loaf pan with parchment paper.
- Combine. Blend the whey protein powder, eggs, almond butter, and baking powder together in a food processor.
- Transfer. Pour the batter into the lined pan.


- Bake. Keep bread uncovered until the top is golden brown. Once it’s golden, tent the top with foil and continue baking until an inserted toothpick comes out clean.
- Cool. Let bread cool in the pan until it’s no longer hot, then use the edges of the parchment paper to remove to a cooling rack. Cool completely before slicing.



Tips For The Best Protein Bread
There are a few key tips to follow when making flourless protein bread in order to get the best results.
- Use the right protein powder. I mentioned this above, but I can’t stress this enough! Whey protein isolate is needed for this recipe to work, and I can’t guarantee that other protein powders will produce the same result.
- Use room temperature ingredients. Room temperature ingredients mix together more easily and produce a more consistent final product.
- Use extra parchment paper. Use enough parchment paper that it hangs over the sides. This will make for easy removal later.
- Don’t over mix. Over mixing can result in a tough, dry loaf of bread. Blend in the food processor until just combined.
- Let the bread cool before slicing. This step lets the inner texture of the bread settle, so that it doesn’t come out gummy or wet.

Storage Instructions
- Store: Flourless protein bread can store in an airtight container in the fridge for up to 1 week. If it gets a little moist, you can pop the slices in the toaster.
- Meal prep: Making this bread ahead of time is a great way to prep for a high protein lunch or dinner. Simply make the bread and store for later.
- Freeze: Wrap flourless gluten free bread tightly in plastic wrap and place in a freezer bag. Freeze for up to 3 months. Thaw in the refrigerator overnight before using.
Ways To Use Flourless Bread
Whether you’re looking for nutritious lunches or quick breakfasts on-the-go, here are some unique ways for using protein bread in your everyday meals!
- Sandwiches – Try a chicken breast sandwich with homemade avocado oil mayo, or make a gluten free BLT, reuben, or peanut butter and jelly.
- Spreads – For delicious flavorings, smear with some sugar-free Nutella, nut butter, or even strawberry chia jam or sugar-free jelly.
- Side Dish – Pair this bread with your favorite healthy dinner, salads, or soups.

0Can I substitute egg white protein powder for the 4 large egg whites? and if so, how much would I need?
Maya | Wholesome Yum
0Hi Diane, I haven’t tried that, but don’t think it would work since it would throw off the wet/dry ratio.
Diane Swarthout
0I have made the egg protein bread, and we really like that, but it doesn’t toast well, and only gets tougher to chew. I have also made the simple almond bread recipe, which is also good, but again, just doesn’t toast well. I’d like to know if you have a keto recipe for a full size loaf of bread (that rises up somewhat like a normal loaf) that will toast well, and taste like toast. I get really hungry for crispie toast, and nothing so far has worked. But I do also want to try this protein bread and see what that’s like.
Wholesome Yum D
0Hi Diane, Here is my recipe for keto yeast bread.
Shirley
0Hi Maya,
thank you for your receipes! I made the protein bread but it is a little dry, maybe baked a little too long? Other than that, it is a beautiful loaf of bread that can be toasted and also used for sandwiches. I really like that it is high in protein as I need to increase my protein intake. Have you tried it using any seeds in it? I was thinking of sunflower seeds and/or flax seeds.
Lisa
0Looks lovely; tastes nothing like bread and is actually pretty awful. Ended up throwing most of it out.
Jenni
0Hello, I’m just wondering if this recipe could be modified to make hamburger buns if made in a burger bun pan or even jumbo muffin tin? Thanks in advance for your reply
Maya | Wholesome Yum
0Hi Jenni, I haven’t tried that but I think you can. Let me know how it goes if you try it!
Jeannie
0Hi Maya thank you for all your recipes! I wanted to know if I can use liquid egg whites from a carton?
Wholesome Yum D
0Hi Jeannie, Yes, that should work.
Janet
0Would a plant based protein powder work? I can’t have dairy products.
Wholesome Yum D
0Hi Janet, Yes, that would work.
H.J.
0Hi, I am substituted almond butter with sunflower butter. Do I need to cut down the baking powder; to prevent inside the bread turn green?
Wholesome Yum D
0Hi HJ, I have not tested this recipe using sunflower butter so I have no suggestions on adjusting the baking powder.
Lilian K
0Can you add raisins and cinnamon to make it taste like raisin cinnamon bread?
Wholesome Yum D
0Hi Lilian, I have never tried that but if you do, please let me know the results.
Jen
0Could this be adapted in some way to make biscuits?
Maya | Wholesome Yum
0Hi Jen, I haven’t tried that, but the batter is pretty runny so don’t think that would work. Possibly if you use a pan that has separate cavities, such as a muffin pan. Let me know how it goes if you try it!
Julie
0Hi, I’m in the uk, could you tell me how many grams of protein powder and almond butter are equal to 1 cup please.
Thank you
Wholesome Yum D
0Hi Julie, You can change the ingredient amounts from Us customary to metric at the top of the recipe card.
Alina
0Would the recipe work with 1/4 cup coconut flour + 3 extra tablespoons of liquid egg whites, in place of the almond flour? (my son is allergic to nuts).
Sheryl
0I’m confused I don’t see any almond flour called for in the recipe
Wholesome Yum D
0Hi Sheryl, I believe this person was asking about the almond butter.
Wholesome Yum D
0Hi Alina, If you are asking to replace the almond butter, I suggest sunflower butter.
johanne
0You can try tahini to replace the almond butter. I have done this with other recipes. Have not made this yet.
Susan
0Too bad other proteins won’t work for the flourless bread. I’m all about 2-4 ingredient baked goods. I only have a microwave and an air oven. I’m not well and slow, but love to bake and cook when I can. Can’t eat whey protein though. Sounds really good.
I enjoy making your Big Mac salad occasionally. Tastes really good but without the bun and sugar.
I like your chicken one pan roast with vegetables. I do that sometimes. I liked your choice of vegetables. I will try them next time. I like chicken thighs in air oven with saurkraut, carrot pieces and sliced Granny Smith (or your favorite) apple. Very flavorful. Nice change.
Just wanted to say hello Maya. Thank you for all your hard work.
Jan
0Is there really a total of 10 eggs in this one loaf?
Maya | Wholesome Yum
0Hi Jan, There are 6 whole eggs plus 4 egg whites.
Roberta Krouth
0This bread was so simple and so good, raised really nice, better than any of the other bread recipes I have tried of hers. Was concerned it would take like almond butter but it does not. I had an end slice out of oven with butter, ummm ummm good.
Jelka
0Thank you for your site. I really appreciate your simple recipes since I do not like to cook.
I am having trouble figuring out which brand of protein powder you are recommending. When I follow your link to Amazon, it shows some different brands each time. Can you please tell me the name of the brand? Thank you.
Wholesome Yum D
0Hi Jelka, This is the brand of Whey Protein I recommend.
Vicki
0I don’t have whey protein. Can I sub in egg white protein?
Wholesome Yum D
0Hi Vicki, I have never tried it, but egg white protein can usually be substituted for whey protein.
Lorelee
0Did you use vanilla flavored whey protein isolate or unflavored? Can the bread be toasted?
Wholesome Yum D
0Hi Lorelee, I used unflavored whey protein, and yes, you can toast it.
Julia
0I am not much of a baker but this recipe was so easy to follow! It turned out pretty tasty AND its gluten free? C’mon! Thats awesome!
Teresa F
0Wow! We loved this bread, you’d never know there was no flour in there!!
