Peanut Butter Fudge Cups – Low Carb Sugar Free Keto Recipe

You should always have an easy recipe on your to-do list, especially when your primary goal is to eat healthily and still follow the rules of a keto or low carb diet. 

We wanted to combine two delicious things into one because nobody can resist them. That’s how we invented this Low carb Peanut Butter Fudge.

Everyone goes crazy for peanut butter. This popular healthy fat can be used in many different ways, including in savory or sweet recipes that are amazingly delicious. We suggest you make your peanut butter at home to avoid added sugars and vegetable oils.

Simply put peanuts into a blender and blend for a few minutes. It should become smooth and creamy. Depending on your blender strength, you may need to add one or two tablespoons of oil.

Some people do not eat peanuts on the keto diet because they are a legume. However, peanuts are lower in carbs and higher in fat than most legumes, making them an ideal choice for keto dieters. 

Research that peanuts are also incredibly healthy, as long as you avoid the highly processed peanut butter brands that most grocery stores sell for cheap. The fat profile in peanuts is made up of approximately 50% heart-healthy monounsaturated fatty acids. 

One study found that when compared to a low-fat diet, peanut products help lower total body cholesterol, thanks in part to their monounsaturated fats (*).

In fact, the benefit of a diet high in peanuts was comparable to olive oil in terms of reducing cholesterol levels. Other research shows a link between eating monounsaturated fats from nuts and a reduced risk of coronary heart disease (*). 

When someone mentions fudge, we always think about the rich and creamy treat that melts in your mouth. With some good replacement for unhealthy ingredients, you do not need to give up on your fudge even on the keto diet!

This simple combination of sweet and creamy is going to blow your mind with only one piece! There’s no need to buy sugar-free desserts when you can easily make it at home.
