My aunt made this cookie cake all growing up. It is super easy and WAY better than any cookie cake you can buy (and way cheaper:)). In fact I was reminded how yummy it is when my mom made it for my birthday this weekend!
1 box yellow cake mix
2 eggs
1/2 cup oil
1 teaspoon vanilla
1 bag of chocolate chips
Preheat oven to 350
Mix cake mix, eggs, and oil. Add vanilla and stir. Add chocolate chips. Spread mixture in a well greased pizza pan. Bake for 18 minutes.
