This is a super simple keto peanut butter fudge recipe but the results are so impressive! You can’t beat homemade peanut butter fudge and if you’re on a low-carb diet, it’s the perfect sweet treat!

It’s also so rich and velvety that you only need a few bites to feel satisfied which makes it perfect for portion control.

Now, this sugar-free peanut butter fudge recipe has a secret ingredient that helps give it structure and makes it velvety smooth. If you’re a regular reader here, you won’t be surprised to learn it’s cream cheese!

We LOVE to use cream cheese in our keto baking around here! The use of cream cheese not only gives them a perfect consistency but also adds a little more protein and fat. 

The addition of cream cheese (and the butter) is why this fudge is also considered to be a fat bomb. So not only are you getting a yummy treat but it’s a great way to increase your fat macros while doing a ketogenic diet. 

What Is A Fat Bomb?

Why should you be eating fat bombs if you’re trying to lose weight? You may be asking why you should bother adding them to your diet. When it comes to fat, especially when everyone has told you that fat makes you fat!

The Keto diet focuses on consuming more healthy fats and fewer carbs. When you deprive your body of glucose, the body goes into ketosis.

This gives your body the chance to burn fat for energy instead of carbs.

The goal of a ketogenic diet is for your primary source of energy to come from fat. However, if you’re new to a low-carb, high-fat diet, adding fat to your meals may seem strange.

Adding more good fats to your diet can help you keep your appetite and cravings in check, have more energy, control sugar cravings, and much more!

This is why keto fat bombs may be the answer to how to stop craving sugar. Fat bombs provide healthful fats without carbohydrates or sugar to satisfy your sweet tooth!

So, how do you make Keto Peanut Butter Fudge? Well, the process of making the no-bake fudge is pretty simple and the hardest part is waiting for it to set before eating it all!

All you need to prepare this sugar-free peanut butter budge recipe is to combine peanut butter, cream cheese, and salt. Then you’ll add in the melted butter and vanilla extract and carefully mix it all up.

You’ll add the powdered sugar substitute half at a time, combining completely in between. Then all that’s left is to pour your mixture into your prepared freezer-safe dish, sprinkle with chopped peanuts, and sea salt flakes, and place in the freezer.

It’s truly that simple to make!

How To Store Keto Peanut Butter Fudge

The ideal place to keep this keto fudge is in the refrigerator for up to 10 days or the freezer for a month. Although it may be kept longer, I believe the tastes would begin to deteriorate after being frozen for an extended period of time.

Personally, I prefer to keep my fudge already sliced and separated into small servings. However, you may store the entire slab of fudge and cut it before eating.

Just remember you can’t keep it at room temperature, you must freeze or chill it. Since cream cheese is among the ingredients in this recipe, it must be refrigerated at all times.

Join Our Jesus And Keto Movement 

In case you don’t know, Randy and I came to the keto diet looking at it from a Christian perspective. As believers, we live our lives supported by God’s grace.

So when the Holy Spirit led us to combine our Christian faith and the keto diet, we did so in hopes of finding lasting transformation.

To say we needed God’s intervention is putting it mildly. When we followed the Holy Spirit’s prompting to we got on the path to real transformation. 

Knowing firsthand the benefits of this decision we have created a closed Christian group that is using the keto diet to transform their lives.  We invite you to join our Private Facebook Group and see if it’s not the key you have been missing.
