How to make No Bake Peanut Butter Fudge

Step 1 – Line a 6-inch square cake pan with a piece of parchment paper. (I cut mine 6”x10” so two sides are longer and stick up slightly for easy removal.)

Step 2 – Add the salted butter and peanut butter to a medium saucepan over medium heat and bring to a rolling boil, stirring occasionally.

Step 4 – Transfer the peanut butter mixture to the prepared pan and smooth the top of the fudge flat. Cool at room temperature, for about an hour, until set.

Step 5 – When the homemade peanut butter fudge has set, run a knife gently around the edges and invert it onto a cutting board. Remove the parchment paper and cut it into 9, 12, or 16 equal small squares.

Serve and enjoy!

Recipe FAQs

Can you freeze Peanut Butter Fudge?

To freeze, the fudge should be frozen in as large a block as possible, as it can dry out more easily when cut into smaller pieces. Wrap chilled fudge in plastic wrap and then transfer to a freezer storage bag. Freeze for up to a month and thaw in the fridge.
