Perfect Party Cookies

I made these adorable and delicious cookies for my son's 5th birthday party! They were a huge hit, I love that they were fun and festive sitting on the table. The recipe is from Stephanie Cooks and she hit a home run when she created this recipe!

1 cup flour
1 cup yellow boxed cake mix
1/4 tsp baking soda
3/4 cup butter (melted then slightly cooled)
1 egg
1 egg yolk
2 tsp. vanilla
1/2 cup sugar
1/2 cup brown sugar
1 cup chocolate chips
4 tbsp colored sprinkles

In a bowl stir together the flour, cake mix and baking soda. In a separate bowl beat together the butter, egg, egg yolk, and vanilla until creamy. Add the sugar and brown sugar and stir in. Add the flour mixture to the butter mixture and stir. Stir in the chocolate chips and sprinkles. Heat oven to 350 and refrigerate the batter for 30 minutes. Bake for 12 to 15 minutes. Keep dough cool if not being baked. Cool for 5 minutes on pan then place on a baking rack.
