These delicious peanut butter cookie bars are loaded with peanut butter fudge, Reese's pieces, and a buttery cookie crust. A perfect treat for any occasion!
Beat Crisco with creamy peanut butter, milk, and light brown sugar until creamy. Add egg and mix well. Stir in flour, kosher salt, and baking soda until fully combined.
Press the cookie dough evenly into a lightly greased 15x10 inch baking sheet. Bake at 375°F for 15-18 minutes until the edges are golden brown. Remove from oven.
While baking, warm the sweetened condensed milk with unsalted butter over low heat. Remove from heat and whisk in peanut butter morsels until melted and smooth. Pour mixture over the warm cookie crust.
Immediately press Reese's pieces and MINI peanut butter cups into the peanut butter fudge layer. Allow bars to set for about one hour before slicing and serving.
