If you love peanut butter and are heading out to a potluck or dinner party, take a batch of this creamy sugar free fudge. Everyone will happily munch away on it until it disappears, and they won’t even realize that it's a low carb diet recipe. The creamy texture of gluten free keto fudge leaves a lasting impression on anyone who tries it.
I wasn’t kidding when I said you only need 2 ingredients. Not only does it taste incredible, but it’s also not going to cost you a lot to make it either.
Sugar-Free White Chocolate Chips - I used the ChocZero white chocolate chips because they melt really easily. (Save 10% with code "joyfilledeats").
Natural Peanut Butter - Make sure to choose one without added sugar. I use creamy peanut butter. If you want a little more texture in your fudge go ahead and use crunchy peanut butter!
How Do I Make Keto Peanut Butter Fudge
As you will see, there are only two easy steps to making this sugar free peanut butter fudge. You can throw it together in just minutes. The part that is the most difficult is waiting for it to set up because you are going to want to eat it so bad.
Step One: Melt the sugar-free white chocolate chips with the peanut butter in a microwave-safe bowl in the microwave. Stir every 30 seconds until melted.
Step Two: Pour the fudge into a mini loaf pan that has been lined with a piece of parchment paper. Alternatively, you can grease a shallow pan very well with coconut oil.
Place the keto peanut butter fudge in the fridge for 4-6 hours or overnight until it’s set up.
Cut, serve, and enjoy! The nutrition facts are based on 16 servings. Since fudge is so rich a small serving should satisfy your sweet tooth. You can slice it into thin slices, or thick slices and then cut it into cubes.
If you want to add a few ingredients on top of the low carb keto fudge, go ahead. Whatever you use, sprinkle it on top of the low carb peanut butter fudge after you put it in the loaf pan. Then refrigerate as directed. Here are some ideas:
Crushed Peanuts - They will give the fudge a crunch and looks pretty too. Crush up ⅛ - ¼ cup and sprinkle on top.
Chocolate Chips - Use some sugar free chocolate chips in any flavor and add them to the top of the fudge. Dark chocolate will look fabulous and help you with your craving for chocolate.
Salt - A little bit of flaky salt would be a nice touch and give you some added flavor. If you use salted peanut butter, you may want to skip extra salt, so it’s not too much.
Nuts - Pecans or walnuts are great options to add to the fudge too.
Peanut Butter Cups - Chop some sugar free keto peanut butter cups and mix them in or sprinkle on top.
Truffles - Chill, scoop, roll into balls, and coat with powdered sweetener.
Is All Peanut Butter Low-Carb? Is Peanut Butter Keto?
No, not all peanut butter is going to work on a keto diet. It’s vital to check the labels and choose a peanut butter that is all-natural. It should only be made with peanuts. If you find some that have peanuts and a little bit of salt, that’s okay too.
Peanut butter becomes a problem when it’s filled with sugars and other ingredients that aren’t keto-friendly. As long as you read the labels, you shouldn’t have any trouble finding a sugar free peanut butter that will work for you.
Can I Use Different Kinds Of Nut Butter?
Sure! If you have a peanut allergy or ran out but still have a craving for fudge, you can totally swap it out. Use any of your favorite keto-friendly nut butter and follow the same directions. The flavor is going to taste different, so you are going to want to consider that when deciding what to use. Almond butter or cashew butter would be pretty tasty options.
Additionally, you can swap the nut butter for seed butter as well. Sunflower seed butter is another great option to consider.
Is It Okay To Make The Fudge On The Stovetop?
Yep, if you’d rather make it on the stovetop instead of the microwave, that’s fine. BUT you need to use a double boiler and stir it continuously. You don’t want it to burn, or it will ruin the fudge.
- Melt the white chocolate chips and peanut butter in the microwave, stirring every 30 seconds.
- Transfer to a mini loaf pan lined with parchment paper.
- Refrigerate until set at least 4-6 hours, preferably overnight.
