Buttery and flaky shortbread is covered with a rich chocolate peanut butter mixture then topped with peanut butter cup minis in these Chocolate Peanut Butter Shortbread Bars. Rich like fudge, this dessert is not for the faint of heart.
Line a 9x9-inch square pan* with and over-hanging piece of waxed paper or parchment paper.
Mix butter, sugar and flour until it resembles wet sand.
Press evenly into pan.
Bake for 15 minutes.
Meanwhile, mix peanut butter and sweetened condensed milk until well combined.
Pour over shortbread crust.
Bake 20 minutes. The top will change from shiny to matte when ready.
Remove from oven and immediately top with 2 cup Reese's minis.
Cool completely before cutting.
Notes
Store in an air-tight container in refrigerator up to one week. *an 8x8 inch square pan may also me used. You may need to cook 1 to 2 more minutes, so keep an eye on it.
