Keto peanut butter fudge made with cream cheese has a smooth creamy texture. It’s one of the best low carb and sugar free fudge recipes ever!

I was looking for a new low carb fudge recipe to share over the holidays. The cream cheese gives it a creamier texture than my pumpkin fudge or coconut milk fudge. So give this keto peanut butter fudge a try and see for yourself.

This sugar free treat is everything that fudge should be. It’s high fat, sweet, creamy and just melts in your mouth.

I’m very impressed with how this fudge turned out. You can easily pass it off to your friends and family as the real thing. 

I can assure you that this is one of the best keto cream cheese recipes you will ever make! And it’s sure to satisfy a sweet tooth on a keto diet.

How to Make Low Carb Peanut Butter Cream Cheese Fudge

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.

The recipe begins by melting two sticks of butter with one eight ounce block of cream cheese.

Once the cheese and butter are melted together, stir in the peanut butter. I use natural unsweetened creamy peanut butter in the keto cream cheese fudge.

Once the peanut butter in blended in, remove the pot from the heat. Then, add the remaining ingredients.

• Vanilla extract adds a touch of sweetness and enhances the flavor.
• Powdered Sweetener adds sweetness and stiffens the mixture.
• Stevia Extract Powder is used to reduce the amount of powdered sweetener needed. Monk fruit powdered extract can be used instead.
• Unflavored Whey Protein Powder is added to stiffen up the mixture without the need to add additional powdered sweetener. Any unsweetened plain protein powder will work including collagen powder.

If the mixture is too hot, there may be some oil separation that occurs. But this is easily remedied by allowing the mixture to cool down a bit and using an electric hand mixer to blend things together well.

Once everything is blended together well, pour the mixture into a 9×9-inch lined or greased baking pan. I use parchment paper so the keto peanut butter fudge will lift right out of the pan.

After spreading the mixture into the pan evenly, 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.

How to Store the Keto Peanut Butter Fudge

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 3 months in the freezer.

You might want to hide these little bites of peanut butter heaven in the back of the fridge. That’s because putting them out front in the open could be dangerous.

When the fudge is in sight, you’ll want to grab a piece every time you open the refrigerator door. Believe me. It’s hard to resist!

Sugar Free Peanut Butter Fudge Variations

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 add in low carb chocolate chips or swirl in some dark chocolate keto fudge.
