Peanut Butter Recipes

Having our homemade peanut butter in mind, you can start making some delicious desserts such as Instant Pot Peanut Butter Cheesecake, Keto Peanut Butter Mousse, or Easy Peanut Butter Cookies.

With today’s Sugar-Free Peanut Butter Fudge recipe, you will have to keep making your peanut butter day after day. 

Is Peanut Butter Keto?

A simple answer is yes. Peanut Butter is Keto. 

Peanut Butter made with only peanuts, and no additional ingredients is entirely Keto, Low Carb, Sugar-Free, Gluten-Free, and a perfect idea for Diabetics.

You can even add your preferred sweetener to have a more sweet taste, and you will still have Sugar-Free Peanut Butter made at home. 

With its great fat content and minimal carbohydrates, it is an excellent snack in between meals, which will keep you full for a long time. 

Keto Fudge

Fudge has been and still is one of my favorite candies of all. When we transitioned to a Low Carb lifestyle, I used to buy various available Sugar-Free Candy, not knowing you can make your own.

That soft, chewy, creamy, and silky smooth texture you get from this Keto Fudge is just fantastic the whole way.  

Here we are, a few years on, and I have not stepped into a Sugar-Free Shop to buy anything apart from some important Keto Pantry Ingredients. 

Having your Homemade Sugar Free Peanut Butter Fudge Recipe whenever you want is just a step closer to maintaining this incredible lifestyle. Don’t you think so?

Keto Peanut Butter Fudge

Our Low Carb Peanut Butter Fudge consists of only 3 Ingredients, out of which peanut butter is homemade as well. So, all you will need is peanuts, sugar substitutes, and butter. That’s it. 

I mean, you can, of course, use store-bought peanut butter if you like, but making your own will for sure save you some money and lower the carb intake as you know that all you have put into the butter is pure peanuts. Nothing else. 

3 Ingredient Peanut Butter Fudge

Our 3 Ingredient Peanut Butter is what you need. You might not even know it yet. But taking into account that you can make this delicious Sugar-Free Candy and have it stored in your fridge for weeks, you need it. 

No Cream Cheese Keto Fudge

Before I go further, I have to let you know that this recipe does not contain cream cheese. You might have seen lots of keto fudge recipes involving cream cheese. 

And frankly. 

Why would people add cream cheese into fudge?

Maybe some love it, but I am sure many do not agree with adding cream cheese to the Keto Fudge Recipe.

And I am one of them.

And for those, our Recipe for Low Carb Peanut Butter Fudge is the right fit. 

Is Fudge Gluten-Free?

To answer the question if Fudge is Gluten-Free, I have to reply: It depends.

It depends on the ingredients you put in or the ingredients contained in a store-bought Fudge. 

Our Recipe is entirely Gluten-Free, as all you are using here is peanuts, butter, and sugar substitute.

But for any other fudge, please read the labels always. 

Can I have Desserts while on Keto?

When you are just starting Keto or Low Carb Lifestyle, and this is the first sweet recipe you are reading, you might ask yourself if you can have desserts on Keto. 

The simple answer is yes, but you would still have to watch your carbs and, of course, calories.

Because if you have decided to start Keto to lose a few pounds, even though cutting carbs will help, counting calories is essential in the long run.

You might have lost a few pounds at the beginning, but if you are for this in the long term, there comes the time when your weight will stall even though you are following carbohydrate intake.

Calories in Keto

And there, the answer is calories.

Because let us go straight to the point, you can have Desserts on Keto, but not only desserts. You can not eat a whole cake every single day.

All of the blogs and recipes we are developing for you that are part of the Keto Diet are great. But all of the Keto Desserts recipes need to be taken with caution and not consumed for Breakfast, Lunch, and Dinner every day. 

How many Carbs are in Peanut Butter Fudge?

Regular Peanut Butter Fudge contains approximately 7 grams of carbohydrates per candy. 

With its 1.2 grams of Fiber, it will take you to approximately 5.8 Grams of Net Carbs. 

How many Carbs are in Sugar-Free Keto Peanut Butter Fudge?

Taking our recipe into consideration, one Candy contains 2 grams of total carbohydrates.

Its Fiber intake is one gram per Keto Candy, giving you a total of 1 gram of Net Carbohydrates.

Do you see the difference now? 

Isn’t that awesome?

Have I already convinced you to make this Easy Peanut Butter Fudge?

What is the best sweetener for Sugar Free Fudge?

In general, any Keto Sugar Substitute you have at home should and will work with making Fudge. The only difference might be the texture. 

My favorite is allulose, which adds softness and creaminess to the fudge.

The second option would be a Monk Fruit Sweetener Blend with Allulose.

Erythritol would be my least favorite choice as some brands might recrystallize after a cool-down period, and you might feel a few grinning inside. 

But if Erythritol is the only one you have at home, go for it. Make sure you use a powdered version, as this might help slightly. 

What can you add to Peanut Butter Fudge?

You can play with various alternatives to make your Peanut Butter FudgeCandies every time a bit different.

Here are just some ideas I have in mind:

  • Sugar-Free Chocolate Syrup – pour our homemade Sugar-Free Chocolate syrup over to get a full keto dessert. 
  • Coarse salt – as salt is part of the peanut butter, spreading the coarse salt on top of the Fudge will give that perfect slight salty taste
  • Chopped Nuts – again sprinkling crushed nuts or peanuts on top of the fudge before it hardens is a great idea
  • Chocolate Chips – adding White or Dark Sugar-Free Chocolate chips into the mixture before placing it into the fridge for cooling does give you that perfect chocolate flavor. Make sure you add chocolate chips only when the mixture has cooled down; otherwise, the chips might melt in.
  • Sprinkles – Our colorful Sugar-Free Sprinkles will make every kid ask for more
  • Condensed Milk – you can experiment by adding Sugar-Free Condensed Milk instead of sugar. In this case, you can skip the butter, which will bring you to a total of 2 ingredients Keto Fudge. 
  • Cocoa – After the mixture is cooked, add Cocoa powder, transforming those Peanut butter fudge candies into a perfect flavor of chocolate and peanut butter.

STEP BY STEP INSTRUCTIONS ON MAKING THE BEST  EASY RECIPE FOR PEANUT BUTTER FUDGE 

First Step: Ingredients needed for keto fudge

Prepare all of your ingredients.

If you would like to make your peanut butter, we have a whole recipe with tips and tricks on this. 

I would suggest going with Allulose as a first option, followed by Monk Fruit Sweetener Blend with Allulose for a sweetener.

Second Step: Butter and Sweetener

Heat your stove to medium and add butter into it.

Let it slightly melt and add sweetener as well. 

Using your whisk, let all sugar sweeteners melt and whisk, so both ingredients get combined. 

Let it cook for a few minutes, just so some liquid evaporates, but not on high heat, so your butter does not burn.

Third Step: Peanut Butter and cook

Add your homemade or store-bought peanut butter and whisk again until thoroughly combined.

Here you have the option of adding Vanilla extract if you wish so.

Fourth Step: Pour and Store

Using a smaller baking sheet, pour the whole mixture and slightly bang against the kitchen counter to eliminate all bubbles. 

Here I would suggest Silicone Flat-form as it will be much easier to take out later on. 

Place into the fridge for 3-6 hours, best overnight.

Fifth Step: Cut

Once your Peanut Butter Sugar-Free Fudge is hard, gently take it out of your silicone form and place it onto the baking paper. 

Using a sharp knife, cut into a smaller candy-like shape. 

As you see in the video, I cut it into 32 pieces.

Hi, Zuzana! I love your recipes. Thank you. When I make the peanut butter fudge and then add the cocoa, how much cocoa do I add? Thank you so much! Denise

it really depends how strong chocolaty you would like to have it. I would suggest 2 - 3 Tablespoons. But it really depends if you want to mix it in or have a kind of swirl peanut butter and cocoa.
