How to make keto peanut butter fudge
It’s ridiculously easy! It’s one of the easiest keto desserts on this blog. The detailed instructions are in the recipe card below. Here are the basic steps:
- Start by melting the ingredients (except for the coconut flour) over low heat.
- Whisk until smooth.
- Off heat, stir in the coconut flour.
- Transfer to a wax paper-lined pan.
- Freeze for 90 minutes, then cut into squares.
A different texture than high-sugar fudge
This fudge is healthier than most. It’s low carb. And it does not contain condensed milk. Or powdered sugar, which most fudge recipes contain because it helps stabilize and thicken the mixture.
Instead, I use coconut flour to thicken it. Even with the coconut flour, it is softer than high-sugar recipes. So depending on what texture you prefer, you might want to keep this fudge in the freezer.
At the very least, you should keep it in the fridge, in an airtight container. Take it out right before you plan to eat it. It will soften quickly.
Right after making it and cutting it into squares, this keto peanut butter fudge is a bit soft. It actually improves the next day, after an overnight rest in the fridge. It keeps well for at least a week, but I doubt it would last you that long.
Is peanut butter healthy?
I believe that American unsweetened peanut butter is indeed healthy when consumed in moderation.
Even if peanuts might be problematic, research shows that processing them into peanut butter greatly reduces aflatoxin concentration.
Whether to eat peanuts and peanut butter or not is ultimately your decision, of course.
But CAN you eat peanut butter in moderation?
Many people say that peanut butter is an addiction. They can eat an entire jar of it!
I don’t believe anyone could actually eat an entire jar of peanut butter, but I agree that there’s something addictive about it. Peanuts have a very unique flavor, and when creamy and sweet-salty, they truly are irresistible.
Personally, I tend to make this recipe only when we have people over. This is the best way to make sure each of us gets no more than one or two squares before they’re all gone!
What sweetener to use in this keto peanut butter fudge?
I use stevia glycerite because it’s my favorite sweetener. I believe that stevia is safe. And although many people object to its taste, the glycerite formulation greatly minimizes the bitter aftertaste.
If you prefer, you could try replacing the stevia with your favorite sweetener. The amount of stevia I use equals about 3 tablespoons of sugar.
It’s probably best to use a powdered granulated sweetener to keep the texture smooth.
