To make these cookie bars, I started by dumping some peanut butter into a large mixing bowl along with some softened butter, brown sugar and white sugar.

I used an electric mixer to cream the ingredients together until smooth.

Then I added some eggs and vanilla and continued mixing with the electric mixer.

I added some all-purpose flour, baking powder and salt to the bowl and continued mixing.

Then I added some mini marshmallows and Skor bits to the bowl.

I used a rubber spatula to stir the marshmallows and Skor bits into the cookie dough.

Then I dumped the cookie dough onto a greased 10 x 15 inch cookie dough sheet and spread it out evenly.

I baked the peanut butter cookie bars until they were just starting to brown across the top.

I allowed the them to cool slightly before slicing them.

The marshmallows melt into the cookie dough as it bakes making these peanut cookie bars extra soft and chewy.
