Line a 9X13 baking pan with aluminum foil or parchment paper. Set aside.
In a large bowl, beat together the butter, confectioner’s sugar, peanut butter and vanilla extract with a hand held mixer or stand up mixer. The mixture will be thick and a bit crumbly.
Use your hands to press the mixture down into the bottom of the 9X13 pan.
Place the chocolate chips and shortening in a microwave safe bowl. Heat in 30 second intervals, stirring after each interval, until melted and smooth.
Spread the chocolate mixture evenly on top of the peanut butter layer in the pan.
Allow to sit at room temperature until the chocolate is fully set.
Then the bars are ready to cut, serve and enjoy!
Recipe Notes
