Lizzy Early's Chocolate Peanut Butter Sandwich Cookies

So my kids really liked these, but Aaron and I thought they were too sweet.  This is an easy recipe, these are out of the cake mix cookbook, but I didn't follow it exactly.  Each cookie was 474 calories, and the boys gave these a 9, and Aaron and I gave them a 7.  Here's what I did:

1 box chocolate cake mix
2 eggs
1/2 c butter, melted
3 T brown sugar
2 t vanilla
1 package peanut butter baking chips

Dark Chocolate Peanut Butter

Preheat oven to 350 and line cookie sheets with parchment paper.  Mix together the ingredients, then form into balls.  Bake for 8-12 minutes (mine went longer), then let cool.
Spread the peanut butter over one cookie, then make a sandwich with another cookie.  Serve.
