Chocolate and Peanut Butter Sandwich Cookies

For the cookies:

Preheat oven to 350ºF. Lightly whisk eggs and oil in a medium bowl. Mix in flour and cake mix until well blended. Roll into 1 inch balls and bake for 8-10 minutes on an ungreased cookie sheet. Cool completely on a wire rack.

For the frosting:

In a medium bowl cream together cream cheese, peanut butter and vanilla. Add in powdered sugar and mix until smooth. Add in milk a little at a time until you get the desired consistency.

Spread about 2 Tablespoons of frosting onto the bottom of one cookie and then place another cookie on top, bottom sides facing in. Repeat with remaining cookies and frosting.
