Fudge without sugar? It’s not only possible–it’s unbelievably delicious! Satisfy your sweet tooth with Sugar Free Peanut Butter Fudge. This easy fudge is rich and creamy, without the sugar crash!
Why This Recipe Works
I can live without a lot of things. Fudge isn’t one of them.
So when I started living a life without added sugars, creating a sugar free fudge recipe was a top priority!
- This Low Carb Peanut Butter Fudge recipe uses erythritol, a naturally occurring sugar substitute, for sweetness.
- Get an extra boost of protein in your dessert with the peanut butter and collagen powder in this recipe.
- No unpleasant after taste or chalky texture. It tastes like your favorite old fashioned creamy peanut butter fudge–only it won’t mess with your blood sugar.
You only need six ingredients and one bowl to whip up this fudge. An easy no bake sugar free treat!
Creamy peanut butter. Make sure to use a peanut butter with no added sugars.
Erythritol. This calorie free sugar substitute can be found in the natural foods section of many grocery stores. Monkfruit powder works in this recipe too!
Collagen Powder. Substitute whey powder or your other favorite protein powder if preferred (or use a combination).
Butter. I always choose unsalted in my baking, and Kerrygold is a delicious option!
First, combine all the ingredients in your mixing bowl. Stir well until smooth and well blended.
Pour it into a 8-inch square dish lined with parchment paper.
Place the dish in the freezer for 1 hour. It’ll firm up similar to the consistency of traditional fudge.
When ready to eat, slice into squares and enjoy!
Tips and Tricks
- The fudge batter is very soft before freezing. Resist the urge to add more ingredients to firm it up. It’ll solidify as it freezes.
- If you freeze sugar free peanut butter fudge for longer than an hour, let it sit at room temperature for 5 minutes before slicing.
- Store any leftover fudge (as if) in an airtight container in the freezer.
Yes, this sugar free peanut butter fudge is suitable for Keto diets.
I don’t recommend using chunky peanut butter here. The nuts will affect how the fudge holds together. If you want some crunch in your fudge, you could sprinkle chopped peanuts on top before freezing!
Yes, this sugar free fudge recipe would work with almond butter, cashew butter or any other nut butter you like! Just make sure to use a creamy variety with no added sugars.
The batter is supposed to be soft when you first combine the ingredients. Make sure to let the fudge freeze for a full hour. If it is still too soft to cut, let it sit in the freezer for a bit longer. If your home freezer gets opened and closed frequently while the fudge is setting, it may take longer to firm up.
Fudge that is frozen for a long time will be extra solid. Just let it sit at room temperature for a few minutes until it’s soft enough to slice.
