To make these peanut butter cookie bars I creamed together some softened butter, peanut butter, brown sugar and granulated sugar.
Then I added eggs and vanilla.
When the mixture was smooth I added flour and baking powder and mixed until a nice dough formed.
Then I stirred in some Reese’s Peanut Butter Cups that I had chopped up and some Peanut M&Ms.
I pressed the dough out evenly onto a large greased cookie sheet.
I greased my baking sheet with Pam Spray For Baking.
I use this cooking spray for pretty much everything because I find it way less greasy than other sprays and also very effective.
I’ve never had trouble removing anything from a pan when using this spray.
Then baked the cookie bars until the top was starting to brown all the way to the center.
After I removed the cookie bars from the oven I allowed them to cool slightly before slicing them into 36 rectangular pieces.
These peanut butter cookie bars are seriously addictive.
The bottom of the bars is slightly crunchy and the center is soft and moist.
The Reese’s Peanut Butter Cup pieces and Peanut M&Ms add great flavour and texture to these cookies.
