Keto peanut butter fudge is high in protein and healthy fats. It's also naturally gluten-free and low in net carbs.
Peanut butter fudge is a wonderful DIY foodie gift too. Almost everyone loves to receive sweet treats as a gift - and they won't even be able to tell that it is sugar-free!
There are just a handful of ingredients in this keto peanut butter fudge recipe. All the ingredients are listed in the printable recipe card. First, I have a bit more information about what I used.
Cream cheese is what gives this keto fudge recipe its thickness and rich flavor. If you don't have cream cheese, you can use Neufchatel or ricotta cheese.
Since there is so much salt in the peanut butter already, it is best to use unsalted butter. But honestly, if you use salted butter, it won't be noticeable.
You can alternatively use dairy-free butter - also called ghee!
Use homemade peanut butter in this recipe if you have some. Otherwise, sugar-free keto peanut butter is the best thing to use.
Vanilla extract adds a touch of sweetness and enhances the flavor.
Sugar-free powdered sugar adds sweetness as well while also stiffening the mixture.
Stevia extract powder is then used to reduce the amount of powdered sweetener needed. Powdered monk fruit extract can be used instead!
This is also added to stiffen up the mixture without the need for additional powdered sweetener. Any unsweetened kind will work, including collagen powder.
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.
- For extra peanut flavor, the whey protein can be replaced with peanut flour. Or, use collagen powder for a dairy-free option.
- The stevia and protein powder can be omitted if you up the powdered sweetener to 2 cups.
- Chocolate chips can be added in or you could swirl in some keto chocolate fudge mixture for something extra.
The process for making the fudge is pretty easy and doesn’t take too long. However, you will need to allow time for it to set in the refrigerator.
Melt the butter and cream cheese
The recipe begins by melting two sticks of butter with one eight-ounce block of cream cheese. Do this in a pot over medium heat.
Add peanut butter
Once the cheese and butter are melted together, stir in the peanut butter.
I used natural unsweetened creamy peanut butter in the keto cream cheese fudge.
Once the peanut butter is blended in, remove the pot from the heat. Then, add the remaining ingredients.
First, you can stir in the powdered sweetener.
Then, mix in the protein powder and stevia. You can adjust the amount of powder as needed to get the right consistency.
If the mixture is too hot, there may be some oil separation that occurs. This is easily remedied by allowing the mixture to cool down a bit and using an electric hand mixer to blend things together well.
Pour into prepared pan
Once everything is blended together well, pour the mixture into a 9x9-inch lined or greased pan. I use parchment paper so the keto peanut butter fudge will lift right out of the pan.
You can also use a loaf pan to make this dessert!
After evenly spreading the mixture into the pan, place it into the refrigerator to chill until set. It should be ready to cut in as little as two hours, but I prefer letting it sit overnight.

Before we get to the printable recipe card, here are some questions people often ask about how to make it.
Yes, you certainly can make this in the microwave. Just place the cream cheese and butter in a microwave-safe bowl. Then, heat it in 30-second intervals, stirring it really well in between.
When it is completely combined, follow the directions in the recipe card like normal.
You will need to keep it chilled as it does have cream cheese in it and gets soft at room temperature. The fudge should last for 2 to 3 weeks in the refrigerator and up to three months in the freezer.
Remember to keep it in an airtight container so that it lasts as long as possible.
You might want to hide these little bites of peanut butter heaven in the back of the fridge because putting them out front in the open could be dangerous.
When the fudge is within your eyesight, you’ll want to grab a piece every time you open the refrigerator door. Believe me - it’s hard to resist!
For cream cheese peanut butter fat bombs, you can add in some coconut oil to increase the fat content. Or, try using some MCT powder instead of whey protein powder.
Not a fan of peanut butter or have an allergy to deal with? Any seed or nut butter will work in the recipe. So try using sunflower seed butter or almond butter in place of peanut butter.
I haven’t tested out a dairy-free version, but the cream cheese could easily be replaced with an almond milk cream cheese style spread. Butter flavored coconut oil is a great substitute for butter, and collagen powder can be used for whey powder.
You can also sprinkle some sea salt on top. This will enhance all the flavors in it.
