½ cup unsalted butter
2 cups granulated erythritol or keto-friendly sweetener
5 ounces heavy cream (instead of half & half for a higher fat content)
1 cup sugar-free creamy peanut butter
2 teaspoons vanilla extract
3 cups powdered erythritol or use powdered monk fruit sweetener

Instructions

1. Prepare the Pan

Start by lining an 8×8-inch baking pan with parchment paper, leaving some overhang on the sides for easy removal. Set this aside. The parchment paper prevents the fudge from sticking and allows for effortless cleanup.

2. Set Up the Sweetener

Add the powdered erythritol to a large mixing bowl and set aside. This step ensures that everything is ready once you need to mix in the peanut butter mixture.

3. Cook the Butter, Sweetener, and Cream

In a medium-sized saucepan over medium heat, melt the unsalted butter. Once the butter is fully melted, stir in the granulated erythritol and heavy cream. Bring the mixture to a boil, stirring occasionally to dissolve the sweetener.

Once it reaches a boil, let it continue to cook untouched for exactly 1 minute and 45 seconds. This timing is crucial for achieving the right texture without overcooking the mixture. The heat will combine the butter and sweetener into a smooth base for the fudge.

4. Add Peanut Butter and Vanilla

Remove the saucepan from the heat. Stir in the sugar-free creamy peanut butter and vanilla extract until the mixture is smooth, creamy, and well-combined. The peanut butter will melt into the warm mixture, creating a velvety texture.

5. Combine the Mixtures

Immediately pour the hot peanut butter mixture into the bowl with the powdered erythritol. Using an electric hand mixer or stand mixer, beat the mixture on medium speed until it is completely smooth and all lumps are dissolved. This process helps incorporate the sweetener evenly and ensures a smooth fudge texture.

6. Transfer to the Pan

Once the mixture is fully combined, quickly pour it into the prepared baking pan. Smooth the top with a spatula to create an even layer. Allow the fudge to sit at room temperature until it is completely cooled and set, which may take about 2 hours. Alternatively, you can place it in the refrigerator to speed up the setting process.

Step 7: Slice and Serve

Once the fudge has set, lift it out of the pan using the parchment paper overhang. Place it on a cutting board and slice into small squares. Enjoy these keto-friendly peanut butter fudge bites as a delicious, low-carb treat!

FAQs

1. Can I Use Almond Butter Instead of Peanut Butter?

Yes! Almond butter works perfectly in this recipe for a slightly different flavor. Just ensure it’s unsweetened and natural.

2. What Sweetener Works Best?

Powdered erythritol is ideal because it dissolves easily and doesn’t leave a gritty texture. You can also use powdered allulose or monk fruit sweetener. Avoid granulated sweeteners as they may affect the texture.

3. How Do I Store Keto Peanut Butter Fudge?

Store the fudge in an airtight container in the refrigerator for up to 2 weeks. For longer storage, freeze it for up to 3 months.

4. Why Is Coconut Oil Used? Can I Substitute It?

Coconut oil helps the fudge set and gives it a smooth texture. You can substitute it with unsalted butter for a creamier finish.

5. Can I Add Chocolate?

Absolutely! Drizzle melted sugar-free chocolate over the top or mix in chocolate chips for a more indulgent treat.

Tips for the Best Keto Peanut Butter Fudge
