Peanut Butter Cup Blondies

Reese peanut butter cups are so classic that they have been used in baking for many many years. There are many different size Reese cups. There are regular, miniature, minis and big cup. Have you seen the big cup? It is huge! The kind that I use are called minis. They come in a bag of 40 or more depending on the size. I actually bought these last week at Dollarama with the plan to use them in some baking. If you cannot find these, the miniatures could also work – you would just need less.

I have always liked blondies as an alternative to brownies and the peanut butter/chocolate combo  flavour is in the spotlight for sure! The batter has peanut butter in it and then there are chopped up minis with chocolate chips stirred in. If that wasn’t enough, there are whole minis pressed into the top. Eat this with a cup of milk and it is pretty close to perfection! This recipe comes from Betty Crocker.

Make sure you press the mini peanut butter cups right when the blondies come out of the oven. They go in far easier while the blondie is so soft. Also, it is very helpful to wait until it is completely cooled and the cups have solidified again before slicing them.
