These flourless keto peanut butter muffins are packed with protein to fuel you through your healthy day. An easy recipe that makes a fabulous on-the-go keto breakfast.
I love keto muffins and I am pretty sure I post a new muffin recipe at least once a month. They’re so easy and ideal for quick healthy breakfasts or keto snacks. And they freeze like a dream.
I also love experimenting with keto ingredients and finding new ways to do things. So these keto peanut butter muffins are entirely flourless. No almond flour, coconut flour, or peanut flour at all.
Instead, I made them with collagen protein powder. And my husband declared that they were some of the best keto muffins I’d ever made! Crazy, right? But it works!
Baking with collagen
In most instances, I don’t recommend using collagen protein in keto baking. I usually use whey protein or egg white protein in keto cakes and muffins because it provides a lighter, fluffier consistency.
I have found that, when baking with almond flour, collagen usually makes the baked goods gummy and hard to cook through.
It makes sense when you think about it. Collagen is one of the building blocks of the human body, and of all animal bodies. It’s in our skin, hair, joints, and connective tissues, and it provides structure, elasticity, and moisture.
In the same manner, collagen protein powder (aka collagen peptides) tends to hold on to moisture, so it can keep muffins and cakes from baking properly.
But I used it very differently in these keto peanut butter muffins. I skipped the flours altogether, didn’t add any additional liquids, and used collagen and peanut butter for structure.
And I was delighted with the results!
Collagen peptides vs. hydrolyzed collagen
So what’s the difference between collagen peptides, hydrolyzed collagen, and collagen powder? If you’re confused by all these different terms, you’re not alone!
Every brand and recipe refers to collagen in various ways, but the truth is that it’s all one and the same. They all contain collagen that has undergone hydrolysis, in order to break the bigger amino acid chains into a more digestible form.
Okay but with so many brands of collagen out there, which ones do you choose?
All I can tell you is that I love Perfect Keto. It’s a little pricier than some but it has incredibly clean ingredients from grassfed animals. It also has some delicious flavoured varieties and I can’t get enough of the salted caramel.

How to make keto peanut butter muffins
These muffins are delicious and easy to make. Here are my best tips for getting it right:
- Line the muffin pan: I always recommend silicone or parchment liners, as keto baked goods can stick more than the conventional kind.
- Melt the peanut butter: You want it to be easy to whisk in with the other ingredients so it needs to be almost liquid before you proceed.
- Whisk in the sweetener: Break up any clumps in the sweetener and try to get it well dissolved into the peanut butter. Then add the eggs and vanilla.
- Stir in the dry ingredients: Add the collagen, baking powder, and a bit of salt and whisk until well combined. The batter should be somewhat on the thin side but will thicken up as it sits.
- Stir in the chocolate chips: I always like to save a few chips for the top of each muffin.
- Bake until golden: The best way to test doneness in keto muffins is the touch test. Simply touch the top of one muffin and if it feels firm, it’s done. Don’t over-bake.
Frequently Asked Questions
This is an unusual keto muffin recipe so I know there will be a lot of questions. I will do my best to answer them here!
Other protein powders work very differently than collagen. I once tried egg white protein in a muffin like this and they were very dry. So I really can’t guarantee this recipe with a different kind of protein powder.
If you do try, I recommend adding some additional coconut oil or butter (about ¼ cup) and adding more liquid if necessary. Make sure you don’t over-bake them.
Yes, any nut butter should work well. If it has a lot of separated oil, make sure to mix it in well before proceeding.
That could be absolutely delicious. The salted caramel or peanut butter flavors from Perfect Keto would be great in these muffins. Do keep in mind that flavoured collagen usually contains sweetener so you may want to cut back on the added sweetener.
To be frank, I am not entirely sure, as I haven’t yet experimented using collagen and other sweeteners. Any erythritol based sweetener should be fine but I can’t be sure how allulose or BochaSweet will affect the results.
If you try, please be sure to come back and tell me how it goes!

Finally got some Collagen and made these with White Choc chips (will try caramel chips one day along with the various chocolates) These are fantastic. Tried one warm out of the oven and then once cooled. DH even ate 2, and he rarely likes LC type desserts/snacks.
Super moist and surprisingly the PB does not leave an over powering flavor.
I used silicone cups and weighed the mix so they all were the same size.
This recipe is a keeper.
Thanks.

Simply delicious

I was very skeptical of this recipe seeing how thick and sticky the batter was (having never used just collagen for keto baking before), but oh my goodness!! These muffins are SO delicious. Highly recommend making these!

Delish! I was out of Swerve brown so I subbed regular granular. I used Vital Proteins collagen. Also, I didn’t have muffin liners on hand so I oiled the pan well with coconut oil. They released beautifully. I put a few in the freezer to take on a plane trip next week. Thanks for another great recipe!

Correction: I meant to say subbed with Swerve granular (of course).

I just bought some at CostCo with a $5 off coupon. thought $25 was expensive until I looked at Amazon and saw it was much higher for the brand I got. I asked Caroline once and she said you need to use Collagen. i got Vital brand and 1.5 pound container.

I didn’t have the Swerve brown sugar do I used Lakanto Golden. I also used the Vital Protein Collagen Peptides. Now that I’m at my goal weight, I’m making these recipes for my weight maintenance.
This one is yummy, keeps me full. My daughter (who is not keto) ate one and said ,”I ain’t mad at it- it’s actually good”.
So that’s a win- I’ll be making these again!
