Butterscotch Bars are made with a chewy oat bar layer which is spread with a butterscotch peanut butter topping, then finished with a decadent chocolate swirl to create an insanely delicious treat!
Line 9x13 metal baking pan with parchment paper or spray with cooking oil.
Oat Bars:
Mix all the oat bar ingredients in a medium mixing bowl until well combined.
Press oat mixture into the prepared pan.
Bake for 10-12 minutes. Do not bake longer! The bars may not look done but they are.
During the last few minutes of bake time, begin to prepare the topping.
Butterscotch Peanut Butter Topping
In a medium microwave safe bowl combine butterscotch chips and peanut butter.
Heat for 1 minute then remove quickly and stir. Place back in microwave and heat another 30 seconds, remove and stir vigorously until topping is creamy and smooth. *You may, depending on your microwave setting, need to heat for another 15 seconds.
Immediately pour topping over bars when they come out of the oven.
Sprinkle mini chocolate chips over the hot bar with topping and gently swirl in the chocolate chips with a butter knife.
Let the bars sit at room temp until topping has hardened or chill in the refrigerator for 15-20 minutes.
