This easy No Bake Peanut Butter Fudge comes out so creamy and silky smooth it melts in your mouth. The creamy texture and peanut butter flavor are fantastic and decadent. It takes just 4 ingredients and just 5 steps to make this delicious treat.
Line a 6-inch square pan with parchment paper. (I cut mine 6”x10” so two sides are longer and stick up slightly for easy removal.)
Add the salted butter and peanut butter to a medium saucepan over medium heat and bring to a rolling boil, stirring occasionally.
Remove from heat and add in the powdered sugar and vanilla, stirring until completely mixed in.
Transfer the peanut butter fudge mixture to the prepared cake pan and smooth the top flat with a spatula. Cool at room temperature, for about an hour, until set.
When the 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 squares.
Notes
Store in an airtight container at room temperature for about 1 week (out of sunlight) or in the fridge for 2 to 3 weeks refrigerated.
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.
