While researching low carb and flourless bread options in order to create my cauliflower bread, I came across a recipe for flourless peanut butter bread. Of course, I had to try it!

I’ve made many flourless peanut butter desserts before so the idea of being able to make a bread didn’t seem too unbelievable. This bread recipe has a preparation process and ingredient list very similar to my 3 Ingredient flourless peanut butter mug cake. In just a few minutes the batter was done and into the oven it went.

Sure enough, what came out was definitely like bread. You can smear it with butter, top it with avocado slices, or maybe eat it with jelly! It holds together quite well.

  1. Super easy. I can’t have gluen or dairy so this is such a great replacement.

  2. Is it important to have the mini pans? I only have a regular size, but I’m worried it won’t come out properly.

  3. This turned out really dry for me and there was barely enough mixture to fill one pan that was a little smaller than recommended (8”/2.5”). Really crumbly and nothing like bread texture. I followed the recipe perfectly so I have no odea what went so wrong

    • Without knowing more details, it’s hard to say what went wrong but did you use three large eggs? If your eggs were small (or if you didn’t add three) that could cause problems with the texture.

  4. OMG! So delicious & easy. I’m a horrible baker, so if I can do it anyone can. This was gobbled up by my family within an hour. Thank you so much!

  5. Where can I find this recipe with UK terms, please? Not only is “cup” meaningless to me, but I have a suspicion that we don’t mean the same thing by “baking soda”.


  6. Recipe looks amazing and I really would love to sink my teeth into it but it seems I must be doing something wrong because I tried it twice and I had to take it out of the oven early because it turned rock hard, was fully black inside :/ i used natural crunchy peanut butter and omitted the sugar. Could that be the reason why?

    • The crunchy peanut butter could be the issue. The crushed peanuts take up space when measuring so you likely didn’t have enough peanut butter in the recipe.

  7. You said that you found this recipe. I don’t see a credit for where you found it. Perhaps I overlooked it? I wanted to thank them as well for this recipe. I plan to try it this week.

    • Hi, I always try to credit the original source when possible. Unfortunately, I came across this recipe when someone left it while replying to a cooking/diet discussion and they did not state where the recipe came from.

  8. Can I use powder peanut butter instead of the typical jar kind?

  9. Awesome recipe! Thank you so much! The texture is very similar to wheat bread. This will be a go-to recipe for my family, and I will definitely be sharing. I didn’t have mini loaf pans, but I had two 8 x 3 and 7 / 8 inch pans. 20 minutes was perfect for that. I also left out the sweetener, and it worked just fine. I used natural peanut butter, ground from my own peanuts. Turned out great! Thanks again!

  10. 1 tbsp vinegar is too much,
    1 tsp vinegar works.

  11. So…I’m wanting to make this ultra moist. What about adding a 1/4 cup of coconut oil? Thoughts?

  12. This bread is fantastic!!! I’ve played around with so many low carb breads but this is definitely my favorite. I’ll admit I was very skeptical but it tuneee our very yummy and actually has a real bread texture. I used almond butter instead of peanut butter. And I used apple cider vinegar instead.
