Protein powder makes this easy sugar free peanut butter fudge a filling treat. It’s a great low carb snack to take along to curb your hunger between meals.
While on vacation last week, we drove by a lot of small candy stores advertising fudge. I knew that I was going to have to make a batch of low carb fudge when I got home.
Searching the internet, there were only a few low carb peanut butter fudge recipes that looked promising. I found an easy sugar free peanut butter fudge recipe at Low Carb Friends.
It got great reviews in the recipe forum. So, I decided to give it a try. I used sucralose as the sweetener, but I’d probably use a stevia blend next time.
I’m moving towards more natural sweeteners. Using a combination of sweeteners in low carb treats also gives a much better flavor.
This is such an easy sugar free peanut butter fudge recipe to make. It has a nice texture and isn’t overly sweet.
I chose to use the liquid sweetener to save carbs. Each serving has about 4 grams of carbs if you use the liquid versus powdered version of sucralose.
UPDATE: A new version of this sugar free fudge recipe is available for those who like peanut butter cups. I added a layer of chocolate to the top of the fudge and it tastes just like a Reese’s Peanut Butter Cup.
