Soft, salted, and the perfect protein dessert. This peanut butter protein fudge will be hard to put down. A freezer fudge recipe that requires no tempering but makes the perfect midday treat. Dairy-free, paleo, and high-protein to give you some fuel at the same time.

Amp up your daily protein intake and curb your sweet tooth. This high-protein freezer fudge makes an easy treat when you have a craving- just like this protein bark.
It’s lightly salted and has all the silky feel of fudge but without all the work.

Why You'll Love This Protein Fudge
Healthy: This protein fudge is naturally dairy-free, gluten-free, and paleo making it a wonderful treat.
High in protein: With 17 grams of protein per square, it's a great way to get more protein into your diet (learn about the benefits of a high protein diet).
Easy to make: There's no tempering or any fancy kitchen techniques.
Texture: Light, silky and ultra-rich, this fudge recipe is the perfect dessert.
Ingredients You’ll Need
One of the perks of this peanut butter protein fudge is that you only need five ingredients, almost like this coffee fudge recipe which requires just six and tastes like a latte.
Because this fudge recipe isn't a traditional one (this is freezer fudge) you also won't need ingredients like unsweetened almond milk either.
If you have a well-stocked gluten-free food pantry staples, you’ll be set.
Coconut oil: I like to use cold-pressed, extra virgin coconut oil but it does have a bit more of a coconut taste to it to some people. Opt for un-refined at the very least.
Natural peanut butter: you need the natural version for this protein fudge recipe so that it creates a smooth texture (same goes for these chocolate chip protein cookies). Also, try to use fresh peanut butter so that it mixes better.
Collagen powder: one of the cleanest sources of protein out there. Collagen is what gives this dairy-free fudge its protein boost.
Honey: not only does the honey sweeten the fudge but it also helps with the texture. Opt for regular raw honey or creamed honey.
Coconut cream: you want the thick, white cream that comes from the can. Make sure to drain the water and use only the cream.
How To Make Protein Fudge
- Combine the coconut oil, peanut butter, and honey in a small pot.
- Heat on low heat until the coconut oil is melted.
- Quickly whisk in the collagen powder and then the coconut cream.
- Whisk until smooth.
- Portion into silicone molds and pop in the freezer for 2 hours.

Important Teaching Tips
To eat the protein fudge, let it sit at room temperature for 5-10 minutes so that it’s soft.
Make sure to heat the ingredients on low and be patient. Otherwise, the peanut butter may burn and make the mixture chunky.
Whisk in the collagen with a fork really quickly while everything is warm. This way it doesn’t have a chance to clump.
If making this in one long silicone mold, run the knife under warm water before slicing the protein fudge into squares.
Though regular peanut butter is great, crunchy peanut butter is amazing (but know that any nut butter will technically work!). Love peanut butter? Check out these gluten-free peanut butter recipes!
Choosing Collagen Powder
It’s no surprise that this protein fudge is made with collagen powder!
All the protein without the bloat.
I use collagen powder for amping up protein and boosting gut health.
Learn about the difference between collagen and bone broth as how to increase protein intake.
Honestly, as a busy mom collagen powder just makes it easy to eat more protein and not feel like I’m living off chicken and eggs.
And more protein means more energy, more natural beauty, and feeling your BEST.
Plus, in recipes like this, you can sneak protein into your kids as it’s one of the purest sources.
I grab my collagen from Perfect Supplements because they source their collagen from pasture-raised (grass-fed) cows. So, I trust it.
Grab some collagen powder and use code mamabear10 to save some money.
Easy to mix, this collagen powder adds a protein punch to anything you pair it with. Made from pasture-raised (grass-fed) cows there are no pesticides, hormones, or filler agents. Just put collagen protein. Use code mamabear10 to save money on your next order.
How To Store It
Store the protein fudge in the freezer for up to 6 weeks (if it lasts that long!).
Let it sit at room temperature for 5-10 minutes before enjoying it.
If you store it in the fridge to thaw overnight it's delicious but just a bit too soft.
Frequently Asked Questions About Peanut Butter Protein Fudge
Because peanut butter fudge requires no tempering, it’s best stored in the freezer until you’re ready to eat it.
Fudge that has not been tempered should be placed in the freezer to set. Setting in the fridge will take hours where as most fudge in the freezer takes only 60-90 minutes.
Freezer fudge can last 2-3 months in the freezer so long as it is in an air tight container in which it can’t get “freezer burn” on it.
Protein powder and collagen powder do not mix or absorb liquid in the same way. Though whey protein powder may be able to be used, vegan can most definitely not be swapped in. Vegan protein powder tends to absorb a lot of liquid and would leave this protein fudge with a thick but chalky texture.
The honey in this recipe helps to sweeten it but also with the texture and binding of the fudge. So, using maple syrup won't work.
You can add chocolate chips to the peanut butter fudge for a fun twist! However, make sure to add the chocolate chips after pouring it into the mold when it has cooled ever so slightly. Otherwise they will just melt.

So, not only was this out of this world delicious, it was also very easy to make. I have worked with collagen before and it clumped! Your trick to stir with the fork while everything was warm, did the trick, thank you for a great recipe and a great collagen tip!
