Creamy, decadent low carb and keto peanut butter fudge. It’s so good, I only make it when we have people coming over, simply to avoid too many tempting leftovers!
You need to be very careful with this low carb and keto peanut butter fudge!
Yes, it’s healthier than most. It’s low carb. And it does not contain condensed milk. Or powdered sugar, which most peanut butter fudge recipes contain because it helps stabilize and thicken the fudge.
Instead, in this low carb peanut butter fudge, coconut flour thickens it. It is still softer than high-sugar peanut butter fudge. So depending on what texture you prefer in your fudge, 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 out of the fridge.
Right after making it and cutting it into squares, this low carb 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.
Even though this low carb peanut butter fudge is healthier, it is dangerous, because it’s so good. Creamy, fudgy and irresistible, it is very difficult to stop at one square. But try: take one square out of the freezer, and savor it slowly, taking small bites. If you enjoy it slowly, you’ll see how satisfying it is.
Is peanut butter healthy?
It’s not paleo, that’s true. And there are fears about the toxin aflatoxin, found in some types of peanuts, and its possible carcinogenic effects. But aflatoxin levels in American peanuts are monitored by the USDA, and peanuts are very nutritious. Some research even shows that peanut butter consumption is inversely associated with the risk of some types of cancer, and that it lowers the risk of type 2 diabetes.
Even if peanuts might be problematic, research shows that processing them into peanut butter reduces aflatoxin concentration by 89%.
Like anything else that’s suspected of possibly causing health issues, it’s probably best to eat peanut butter – and this keto peanut butter fudge – in moderation.
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.
Let’s just say I tend to make this low carb peanut butter fudge 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 in this low carb peanut butter fudge because it’s my favorite sweetener right now. I believe it’s safe. It doesn’t have the unpleasant side effects of sugar alcohol or the menthol aftertaste of erythritol. And the glycerite specifically has much less of the typical stevia aftertaste either. 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.
