Chocolate peanut butter fudge that melts in your mouth.
Plus, this peanut butter & chocolate fudge has all of the additional health benefits of collagen!
This delicious recipe is also low carb, sugar-free, naturally gluten-free, dairy-free, and a THM-S treat.
Let me put it simply – I love Collagen!
I put it in everything I can, beginning with my coffee first thing in the morning.
I often add it to smoothies and shakes to give them an extra boost of protein.
I am always on the lookout for more ways to incorporate it into my diet.
Lets talk a little bit about collagen.
Collagen is a protein that is found in connective tissues throughout the body, including tendons, ligaments, cartilage, and bones.
It's responsible for providing structure to our bodies.
As we age collagen production slows down which results in decreased elasticity of skin and muscles. This can cause wrinkles and sagging.
There are a number of benefits to using collagen as well.
For starters, it is excellent for your skin, hair, nails, joints, and gut health.
Collagen Peptides are typically made from bovine collagen or marine collagen, and sometimes other animal sources.
They can also be made from plants (typically algae).
Collagen Protein is not considered a complete protein. It only has 8 amino acids out of the 9 essential amino acids.
When I first started using collagen consistently, my hair started growing like crazy - collagen protein is great for healthy hair!
My husband can tell a difference in his joints when he uses it.
So what does this have to do with chocolate peanut butter fudge?
Well, I use Collagen Peptides to boost the nutritional value of my fudge recipe!
It has so many health benefits including improving skin health, hair strength, stronger nails, and it helps heal your gut lining.
Collagen Rich Foods
You can enjoy collagen naturally by drinking bone broth or eating other collagen-rich foods, such as bone-in chicken.
As a side note, Vitamin C helps to promote your own body's production of collagen, so it is good to include that in your daily diet as well!
Are Collagen Peptides and Collagen Powder the same thing?
Collagen Peptides is a form of collagen that is easier for the body to absorb.
Is there such a thing as Collagen Protein?
Yes! Collagen is a protein source.
Most collagen peptides have at least a 93% concentration of protein. So one scoop a day = roughly 10 grams of protein.
Perhaps the thing I love about collagen the most is that it is an easy protein source.
I can add it to my coffee, and BAM, I have protein coffee!
I can add it to my tea, and BAM, I have protein tea, or oatmeal, or shakes, or soups, or dip, or, . . . . you get the picture.
I love this stuff! It is easily my favorite health product ever!
Can Collagen Powders replace Protein Powder?
While one serving of protein powder generally has about twice the protein of one serving of collagen powder, in most cases you can use them interchangeably.
So, if you don’t have collagen, buy some! Start using it, and I would love to know what benefits you start reaping!
There is an excellent article here, written by Serene Allison, one of the Trim Healthy Mama authors.
It is a very scientific, in-depth article that explains much more than I can here about collagen, its benefits, and some of the best ways to use it.
Or read this if you are wondering, "What is Collagen, and do I really need it?"
How to Take Collagen
You can take collagen as a simple protein source and can add collagen powder to your morning coffee or tea. Collagen peptides dissolve easily in hot liquids, making them a perfect choice for hot coffee or tea.
My go-to drink for collagen is coffee! (And my sugar-free coffee creamer has collagen built right into it!)
If you want to add collagen peptides to cold liquids, you can easily add them to smoothies and shakes.
But I also love adding them to my baked goods.
Collagen peptides are so versatile, you can put them in any number of recipes to add protein.
The peanut butter & chocolate fudge recipe below is one of my favorite recipes to use collagen in a healthy treat!
There are many different brands of collagen products sold online.
When I first started using collagen, I began with the Zint Nutrition brand.
Now I use Custom Collagen - and I love that you can purchase it in a 5lb bag!
I also use the Collagen Peptides from Thrive Market.
And when I want flavored collagen, I get them from Perfect Keto!
Vital Proteins also has a number of collagen products - and you can even purchase them at Costco!
The Vital Proteins collagen products even have a matcha tea collagen powder that would be delicious mixed with warm coconut milk, cashew milk, or almond milk.
Peanut Butter & Chocolate Fudge
Peanut Butter & Chocolate is a classic duo for a number of reasons, but adding collagen peptides to this recipe really ups the ante!
My whole family loves this fudge!
I started out trying to make a sort of protein bar but decided it was more fudge-like than protein-bar-like.
It firms up quickly in the freezer, and melts away in your mouth in a delicious, fudge-like sort of way! Your taste buds will love this easy recipe!
Since this fudge is so quick to make, it is perfect for after-school snacks, or a sweet bite to eat in the evening!
It's the perfect recipe to fight sugar cravings and chocolate cravings!
Plus, this delicious recipe has a healthy dose of coconut oil, so it can help rev your metabolism, too!
Dark Chocolate Peanut Butter Fudge
If you want to make a dark chocolate version, simply use dark cocoa powder.
Your sweet tooth will thank you!
Simple Recipe with Collagen Powder
This simple chocolate peanut butter fudge recipe only takes a few moments to mix up!
It truly is so simple - just mix everything together in a bowl, then pour it in your prepared pan and pop it in the freezer to firm up!
If you want to make it extra indulgent, you could sprinkle some sugar-free chocolate chips on top!
With no added sugar, you CAN enjoy a delicious peanut butter & chocolate fudge without the sugar crash!
Can I use almond butter in place of peanut butter?
Yes, you can easily substitute almond butter for the peanut butter in this recipe.
Can I use cacao powder instead of cocoa powder?
Yes, you should be able to use cacao powder in this recipe.

This fudge looks AMAZING! What a great idea. I actually have some collagen protein in the cupboard which I haven't used in a while. Now that I know it makes hair grow like crazy, I'll have to start making some fudge asap. Thank you for the recipe
I'm not a huge fan of chocolate. I've always preferred "white chocolate". I wonder if I could just leave out the cocoa powder and have it turn out?
Yes, I would think so!
Can I use trivia in place of the gentle sweet? Or will it leave it kinda grainy?
I think it would be grainy, but if you ground it (in a coffee grinder or Ninja) first, I think it would be okay.
what kind of collagen do you use?

I haven't jumped on the collagen band wagon yet. I do enjoy gelatin occasionally and try to make bone broth when I have the bones, but honestly, this looks like a yummier option! I'll have to get some and try. I love seeing your toddlers hands in the pictures. Yep, you can tell she loves it. Thanks for the recipe.
Chocolate and peanut butter has always been my favorite combo!
Maya | Wholesome Yum
These look wonderful, I love a good, healthy fudge recipe! Can't wait to see what collagen can do for me!
I've just made some peanut butter fudge and as weird as it sounds, added turmeric (to get my turmeric without tasting it.) I'm going to add the turmeric to this recipe and see how it works. I love the chocolate/ peanut butter combination.
This looks so yummy, and I love that you added collagen to it. Collagen is so awesome for your skin, hair and nails! I know what you mean though, when I add gelatin to a recipe some people get all freaked out (vegan maybe).
Hi - I made this exactly as instructed using ingredients named. It was good but the gritty taste is bothersome. How do I get rid of that. I don't see where any of the ingredients would have caused this. Maybe the Gentle Sweet? Any suggestions?
Did you use a homemade Gentle Sweet or the Gentle Sweet directly from THM? I know sometimes when I make my own I don't get it ground finely enough. I honestly don't know what else could be the culprit.
Aloha, I use a healthy sugar substitute I get on Amazon it's a confectionery powder so it Blends much more easily in no bake items like this and also makes fabulous frosting! Swerve
I would love to know what collagen you recommend.
I have used both the Trim Healthy Mama Collagen and the Zint brand. 🙂
This looks like the most perfect fudge! Love the added health benefits of collagen in a fudge.
Do you think there is anything else I can use in place of the coconut oil? When I make skinny chocolate it makes me sick to my stomach which I'm pretty sure is the coconut oil since I have no problem with any of the other ingredients in other recipes.
Hmmmm . . . I'm not sure. The coconut oil is what gives it the texture. You could try it with melted butter, but I can't guarantee results. The butter taste may overpower the other flavors.
I love collagen and I think this is an amazing way to get into my days! Yum!
I just wanted to thank u for this recepie. It is fantastic. I made it last night.
Is the coconut oil measured (3/4 cup) before or after melting? I just got some refined coconut oil and I'm looking forward to trying this yummy treat.
I usually measure the 3/4 cup after it is melted.
Hi, looks like a wonderful recipe. I was wondering if you think I could use honey instead of the gentle sweet? TY
I used Gentle Sweet because of its low glycemic index. However, I think honey could be used in this recipe, and it still should work! 🙂
Would unrefined coconut oil work in this recipe? Thanks!
Absolutely! The only reason I used refined is because I didn't want the coconut flavor. 🙂
Do you have to use peanut flour? What about almond?
If you do not have peanut flour, I suggest using extra peanut butter to replace the peanut flour. Almond flour would tend to be too gritty for this particular recipe. Hope you enjoy!
Well everyone has asked about subbing out something except what I would like to sub out lol.. not a big fan of peanut butter soooo any suggestions as to what I might replace it with??
You could perhaps sub almond or cashew butter?
I can easily see the swap for another nut butter, but what about the peanut flour? Would coconut flour work? Almond flour? What would you suggest? I don't know what works 1:1 with peanut flour, as I've never used it.
I would just use nut butter in place of the peanut flour. It will still work fine! ?
Can you use liquid coconut oil or does it have to be the one in solid form? I wasn't sure if it would harden if i used the liquid. Thanks
I would not use the "always liquid" coconut oil in this recipe. I would melt the regular coconut oil and use that. The "hardening" effect is what gives it the texture. 🙂
We have a peanut allergy in our house. If I sub almond butter for peanut can I also use almond flour in place of peanut flour or no?
Yes, I think that would work just fine!
Made 16 pieces...would one piece be an S...want more so good 🙂
Yes, these are an "S" Fuel, and I usually eat two at a time! 😉
I'm planning on making this today! I don't have the peanut flour, do you think in hold use coconut or almond flour?
This might be my favorite thm fudge ever! I gained 2 lbs this week because I had trouble limiting my portion sizes of this! What is the best portion size to stay on plan?
I usually eat 1-2 pieces at a time. 🙂
I do not have peanut flour. Could you suggest a sub, and if so, how much?
If I don't have peanut flour, I just use more natural peanut butter (in equal amounts).
This is my favorite chocolate recipe. I pour into silicone ice tray and then just before hardened put ground sea salt on top...YUMMY!! Thank you for sharing the recipe...now just to only eat 2 🙂
Could I substitute the peanut butter for more coconut oil, and leave out the peanut flour? Or maybe replace the peanut flour with cocoa powder?
If you do not have peanut flour, I would replace it with more peanut butter.
The refined coconut oil that I have is Trader Joe's, and it is more of a liquid than solid. (I keep it at room temperature.). Is refined usually like that at room temperature, or do I need to purchase a different brand? Will refrigeration solid it up?
It will turn solid at cooler temperatures. 🙂 (So, yes, it will firm up in the refrigerator.)
Any advice on subbing the collagen for gelatin? Trying to use what's on hand.
Gelatin will behave completely different than collagen - it will thicken and turn into jello. 🙂 You can omit the collagen entirely, or use protein powder in its place.
Sarah, I don't have gentle sweet, but I have super sweet blend. Would this work, and if so, how much should I use? Thank you!
If using Super Sweet, I would halve the amount and grind it in a coffee grinder to make it powdery, like Gentle Sweet. 🙂
Loved these! Made them with just less than 1/3 cup Gentle Sweet and I probably could have used a bit less.
Very delicious!!! Thanks for sharing! 😉
I started putting Collagen into my morning coffee a few years ago and my knuckles feel so much better. I bet I could get the kids to eat more collagen with this fudge. It's got to be good for their joints too. Thanks!
I can’t remember if I commented on this recipe before, but I have to say, this REALLY hits the spot for me, especially during PMS when I’m craving chocolate & peanut butter the most. I made this at 10:00 last night just so I could have some today! It’s so filling too! I can chase a THM S meal with a small piece of it when I’m feeling a little hungry still & it gets me full. I also like to make it & put it on a cold pack when I’m traveling because it can stand alone as a snack. Thanks for this!!

So so so so good! I can’t stop eating them!
I used almond butter and almond flour; added coconut chips and delivered alomnds for a little texture. Best ever! Super good right out of the freezer!
Just came across this recipe and made it last night, wonderful!
Mine are quite thin (3/8") compared to your photo with the thumb holding the fudge! (I made mine in an 8"x8" too.) Double checked the recipe and my ingredients were right–on; wondering what I did incorrectly? Any ideas as to why mine are not very thick?
I used large flake coconut - if you are using the finely shredded it may make a difference.
This is THE best THM fudge I've made so far. Thank you so much for sharing the recipe!
Hurrah! So glad you enjoyed it! I love that it is a delicious way to enjoy collagen!
Theses are fabulous! I used a peanut butter spread with flaxseed and chia seeds from Aldi and I was short on coconut oil so I added some MCT oil (maybe 1/8 cup), and they came out wonderful! The seeds gave them a little crunch! Thank you for adding the Collagen! Everything in these is healthy, but we to remember these are a TREAT and calorie dense!
