I’ve been sharing so many low carb peanut butter recipes lately! From peanut butter cups to chocolate peanut butter bars, what can I say? I’m a big fan. If you’re a peanut butter lover like me, you have to try this sugar-free low carb peanut butter fudge.

The Best Sugar-Free Keto Peanut Butter Fudge

Hands down, my favorite way to make keto low carb peanut butter fudge is this version with Dr. Axe Multi Collagen Protein. It contains five types of collagen peptide sources, including those from cows, chickens, fish and eggs. You can find it online here.

I believe collagen really can make a difference in supporting the gut, joints, muscles, bones, skin, hair, nails, and even the brain. The fine powder is tasteless, so you can stir into coffee, smoothies, and more. But, my favorite way to use it is this sugar-free peanut butter fudge. The collagen thickens it up perfectly.

Just to be clear, these statements have not been evaluated by the Food and Drug Administration. This is true of any dietary supplement, since the FDA does not officially review them. So, even though I technically can’t say that collagen treats any disease or condition, my opinion is that it makes the ultimate healthy peanut butter fudge.

But you know what really makes this the best peanut butter fudge recipe? The taste and texture! I can’t tell the difference at all between this and regular peanut butter fudge with powdered sugar. It’s pure heaven for any peanut butter lover.

Even if you disregard any potential benefits, you’re going to love this low carb peanut butter fudge. No one will guess that it’s sugar-free and keto friendly. It’s rich, soft and creamy, just like the real thing. Seriously, it tastes just like a regular old-fashioned peanut butter fudge!

How To Make Peanut Butter Fudge with Collagen

Fortunately, making easy homemade peanut butter fudge with collagen protein is incredibly easy! You only need four ingredients, plus vanilla extract, which is optional.

If you like quick and easy desserts and don’t want to cook or even turn on your oven, this one is for you. This no cook, no bake peanut butter fudge recipe only requires a little heating, which you can do in the microwave if you want. The stove-top works just as well, if that’s your preference. Either way, the entire prep takes only a few minutes.

The process to make low carb peanut butter fudge is not much different from other fudge recipes. This one just has the added bonus of being sugar-free and packed with protein. I like to keep some in my freezer for an easy keto treat on the spot.

To make this simple peanut butter fudge, you only have to apply heat for long enough to melt the peanut butter and butter together. Then, stir in the sweetener, collagen powder, and vanilla extract. Pour it into a parchment lined pan and freeze until firm. That’s it. See? I told you it was easy!

1. Line an 8x8 in (20x20 cm) baking pan with parchment paper, letting it hang over the sides. Set aside.

2. Combine the peanut butter and butter in a large bowl (if using the microwave) or saucepan (if using the stove). Heat over low heat, stirring a few times, until melted and smooth.
3. Stir in the sweetener and collagen powder, until smooth. Taste and adjust sweetener if needed. Remove from heat. Stir in vanilla extract.

4. Spread the mixture into the baking pan. Freeze for 30-45 minutes, until firm.

5. To slice, lift the parchment paper out of the pan and place on a cutting board. Run a knife under hot water to warm it up, dry, and use it to cut the fudge into squares. Store in the freezer. If desired, soften on the counter for a couple of minutes when serving.
