These bars came about as an inspiration from a couple different recipes. So I am calling them my own & they are amazing! They are so rich & delicious one piece will satisfy for days (or maybe a couple hours.)  They’ve got a little of everything that one bite makes you wonder what all is in them, hence the name. Anyway, if you are a chocolate-peanut butter fan then you need to put these on your make soon list because they are delish!

Ingredients

  • ½ cup (113 g) unsalted butter
  • ½ cup (100 g) granulated sugar

  • ½ cup (132 g) creamy peanut butter
  • 1 large egg
  • 1 tsp vanilla extract
  • 2 tsp milk
  • ½ tsp baking soda

  • 12 oz (340 g) bag Nestle Semi-Sweet Chocolate Chips
  • ¼ cup (66 g) creamy peanut butter

Instructions
 

  • In a stand mixer, cream butter with sugars. Add ½ cup peanut butter, egg, vanilla & skim milk. Combine & scrape bowl.
  • Add baking soda, baking powder & flour all at once. Mix until just combined. Fold in HALF of the bag of Heath bits, & HALF of the bag of Reese’s chips.
  • Spray a 13×9″ baking dish. Add cookie dough & spread evenly.
  • Bake at 350˚F for 18-24 minutes or until edges & top are browning (mine took 21 minutes.) Let cool completely about 1 hour.
  • In a large bowl combine chocolate chips & remaining peanut butter chips. Microwave for 2 minutes, stirring every 30 seconds, or until melted. Add ¼ cup peanut butter & stir until combined. Spread evenly over the top of the cooled cookie bars. Sprinkle immediately with remaining toffee bits & press down lightly. Let set in refrigerator for 30 minutes. Cut & serve.
  • Extra tip: If the edges of the cookie layer are a little higher than the center after it cools down go ahead & trim them. It will make your chocolate layer spread nice & flat. Just munch on the scraps 🙂
