If you've been following this blog for a while, you'll know how much I love peanut butter. I realised JUST HOW MANY keto peanut butter recipes I have on my website when I recently collected them all in one roundup post!
Well, there's always room for one more, right? Because this healthy peanut butter bread was definitely still missing in my repertoire.
I think you're going to love this sweet bread recipe. It is
- quick and easy to make - only 10 minutes prep
- packed with peanut flavour
- low in carbs and gluten free!
It tastes great all on its own, but you can toast and butter it like a "real" bread for a luscious sugar free breakfast. Or, think of it as a loaf cake and enjoy a slice in the afternoon with a cuppa!
Before we get started, let's clarify something I get asked a lot:
Is peanut butter keto?
That's a yes! Even though peanuts are technically a legume, they are a popular keto food. Peanuts are higher in fat than other beans and they are low in carbs. Nutritionally speaking, they are very similar to almonds. Peanuts are also gluten free.
However, not all peanut butter brands are keto friendly. This is because some contain added sugar. Always read the label! Alternatively, you can also make your own peanut butter.
Peanut butter texture
The correct texture of peanut butter is important for this recipe. Make sure that it is runny and not hard. The dry, firm bits from the bottom of the pot are not what we're looking for here! Stir the pot well before using.
Ingredients
You only need 8 simple ingredients for this flourless peanut butter cake recipe that are all low carb cupboard staples.
- Peanut butter - Ideally, peanut butter should contain just one ingredient - peanuts. Good UK brands are Manilife or Meridian.
- Eggs
- Almond flour - I used ground almonds, which are equivalent to regular almond flour in the US. Super-fine almond flour will also work.
- Coconut flour - It's always best to measure this with a a scale rather than cups because coconut flour absorbs a lot of moisture.
- Almond milk - Check that it is unsweetened.
- Granulated Sweetener - I used a granulated erythritol monk fruit sweetener blend. Golden erythritol would also work, as would erythritol stevia blends, xylitol or allulose. If using xylitol, be aware it's toxic to dogs.
- Baking powder - can be replaced with 1 teaspoon baking soda and 1 teaspoon apple cider vinegar
- Sea salt - only if your peanut butter is unsalted.
How to make keto peanut butter bread
First, preheat the oven to 180 C / 350 F and line a bread pan with parchment paper.
Using an electric mixer or a food processor, blend the eggs until fluffy, light in colour and double the size - about 2 minutes.
Add the sweetener, peanut butter and almond milk and continue blending until a smooth batter.
In a separate bowl, stir together the remaining dry ingredients - almond flour, coconut flour, salt and baking powder. Then, add them to the wet ingredients and mix until well-combined.
Wait 3 minutes to let the coconut flour absorb the moisture. Now, check the consistency of your batter. It should be soft. If your peanut butter was very runny, you may need to add an additional tablespoon coconut flour. If it was firmer, you may need to add a splash of almond milk.
Fill the batter into the prepared bread pan and bake for about 60 minutes. Check the keto bread after 45-50 minutes. If it is golden brown, loosely cover the top with aluminium foil to prevent burning.
Let cool completely before slicing.
Recipe variations
It's possible to replace the peanut butter with other nut butters such as almond butter or with sunflower seed butter.
Using only almond flour: Use 1 ¾ cup or 175 grams of almond flour and omit the coconut flour.
Using only coconut flour: Use ⅓ cup plus ¼ cup or 70 grams of coconut flour and omit the almond flour.
Keto chocolate peanut butter bread: Create a chocolate swirl by taking ½ of the batter and adding 2 tablespoon cocoa powder. Then, follow the instructions in my Peanut Butter Brownies recipe on how to create the marble effect.
Savoury option: Simply leave out the sweetener! The recipe works just as well without.
Storage
Keto peanut butter bread stays fresh at room temperature for 2 days and in the fridge for about 6 days.
It also freezes well. Store in the freezer for up to 3 months.

Made this today. It's so delicious. By far one of the best keto breads I've had.
Katrin Nürnberger
So glad you liked the peanut butter bread recipe!
wyatt
is this recipe gluten free
Katrin Nürnberger
Yes, all my recipes are gluten free.
Jenniffer
I really enjoyed this bread. It was moist too. Thank you for the recipe. Glad I came across it. I read for storage in the fridge about 6 days. I'm pretty sure I've had it in the fridge coveted for more than 6 days. The taste is still th same. It doesn't taste stale at all. The only problem I'm worried about is the eggs after a certain amount of days. But right now I'm still enjoying it. Do you think if it started to go bad due to the eggs being in it, it would have a different taste or smell bad.
Katrin Nürnberger
I think as long as it smells good and tastes good, it's fine.
Sneha
You are awesome and so is this recipe. It came out so good and I am trying really hard not to over indulge. Made this bread with 70gms of coconut flour because I ran out of almond flour. But the moment I came accross this recipe I had to try it. And I am so happy I did. Its taste amazing with Sugarfree strawberry jam.. just yum!!
Thank you for sharing such amazing recipes..
Katrin Nürnberger
SO glad you enjoyed the peanut butter bread! Thank you for your kind words. 🙂
Michele
What size loaf pan should you use?
Katrin Nürnberger
I used a full size loaf pan. it holds 900 ml liquid.
Michele
Thank you
christine
Could you use almond butter as an alternative to peanut butter ?
Katrin Nürnberger
Yes of course. Just make sure it's not too runny. From my experience, almond butter tends to be more liquid than peanut butter.
Joey
I love so many of your recipes but this bread is absolutely delicious! I made modifications…seed flour and HWC as I have a nut allergy and almond milk/flour isn’t possible. I only have chunky peanut butter so mixed that in by hand to preserve the chunks.
I’m not sure what it’s like made per the recipe but even with my modifications it’s fantastic! Thank you!!
Georgia Allison
We don't have almond milk. Could we use fat free low sugar milk? Also, can we use chunky peanut butter if it contains only peanuts?
Katrin Nürnberger
Yes, you can use any milk (although regular milk will add more carbs). Chunky peanut butter would work just as well.
Pattie
Can i use hwc instead of almond milk?
Katrin Nürnberger
That would add a lot of fat and change the texture of the bread. I don't recommend it.
Karin C
I don't have almond milk with me but can I substitute Macadamia milk or coconut milk?
Katrin Nürnberger
Of course, any milk will work.
Nancy
What to try this recipe, looks good. But I don't have almond milk. Can you use regular milk?
Katrin Nürnberger
Yes, regular milk will work as well.
Cheryl
Can powdered peanut butter, like PB2 mixed up to a thin consistency with water be used?
Katrin Nürnberger
I haven't tried it. But if that has the same consistency has peanut butter, it could work. Although I'm guessing that powdered peanut butter may be defatted?
Annie
can you replace eggs with flax eggs or any other vegan substitute?
Katrin Nürnberger
You would have to try that out, I'm not sure as I have not tested it myself. Sorry I can't help!
Margret
This looks so delicious, as do all of your recipes! I was wondering if the loaf pan is that smaller size you usually use or a more standard (for Texas) larger size?
Thank you for all your work on these recipes. I really appreciate your recipes.
Katrin Nürnberger
This is a regular/standard size loaf pan.
Barb Smith
I think I would like to try this but I am allergic to almonds. What could I use as a substitute for almond flour?
Katrin Nürnberger
I have given a conversion to using all coconut flour in the post. You could also try a 50/50 blend of sunflower seed flour and sesame seed flour.
Joey
I have a nut allergy and just used sunflower/pumpkin seed flour that I grind myself 1:1 sub for the almond flour
Maria
Hi!!! Can I use almond butter ?
Katrin Nürnberger
Yes, that would work as well. From my experience, almond butter tends to be more liquid than peanut butter. Check that the consistency of your dough is similar tom mine and add a little more almond flour if necessary.
Karen
If your peanut butter is too firm, can you fix by adding an oil (olive?) or a liquid (ie, almond milk)? Or something else?
Katrin Nürnberger
Yes, any liquid would work. I would probably go for almond milk.
