Step 1: Line an 8×8 inch (20cm x 20cm) square pan with parchment paper. Make sure the paper extends an inch up the sides of the pan.

Step 2: Heat a small pot over medium-low heat. Once the pot is heated up, add the peanut butter, butter, and vanilla. Stir until the mixture has melted and is well mixed together and completely smooth.

Step 3: Remove the pot from the heat and add in the powdered stevia. Mix in well until no lumps remain. 

Step 4: Pour the mixture into the prepared square pan and top with crushed peanuts if desired. Transfer to the freezer to chill for half an hour before cutting the peanut butter fudge into squares. They are very rich so keep the squares on the smaller side.

Storing your fudge

It is not advised to store your keto fudge anywhere else but the refrigerator or freezer. If left out on the counter, your fudge could easily melt.

For long-term storage (more than 1 week), you can store your fudge in the freezer. Use an airtight container to avoid any freezer burn affecting the taste of your fudge. You can store it this way for up to 6 weeks.

The fudge will be quite hard if removed from the freezer but will quickly soften and it should be ready to eat within 10 to 15 minutes.
