Layer the ingredients into the jar in the order listed: oats, flour, brown sugar, sugar, baking powder, baking soda, peanuts, peanut butter cups. It is not necessary by any means, but it is helpful to have a canning funnel to get the ingredients into the jar. It makes far less mess. I take a spoon and spread the layer out to get even-ish lines on the jar.

Wrap and give as a gift with the recipe and instructions included.

To make the cookies, cream together butter and peanut butter. Add the eggs and vanilla.

Take the peanut butter cups out of the jar. Peel off the wrappers and cut in half. Set aside. Pour in the remaining contents of the jar. Mix until combined.

Add the peanut butter cups and mix again.

Using an ice cream scoop, scoop the dough onto a parchment lined baking sheet.

Bake in a preheated 350 degree oven for 12 to 14 minutes. Let cool for one minute and then transfer to a cooling rack to cool completely.
