Birthday Cake Cookies

adapted from sallysbakingaddiction.com. These cookies are so cute, they look like a cross between a cupcake and a choco chip cookie. They would make a great base for an ice cream sandwich.

• Ready In: 40 mins
• Serves: 24
• Yields: 24 cookies

Ingredients

• 1 1⁄4 cups all-purpose flour
• 1 1⁄4 cups  boxed  cake mix (yellow or white)
• 1⁄2 teaspoon baking soda
• 3⁄4 cup unsalted butter, room temperature
• 1⁄2 cup granulated sugar
• 1⁄2 cup light brown sugar
• 1  egg, room temperature
• 1 1⁄2 teaspoons vanilla
• 1  cup white chocolate chips
• 1⁄2 cup  multicolored  candy sprinkles

Directions

1. In a large bowl, sift together flour, cake mix, and baking soda. Set aside.
2. In a separate bowl, cream together the butter and sugars on medium speed. Mix in the egg and vanilla until creamy.
3. Add the flour mixture to the wet ingredients and mix until just combined. Do not OVERMIX the dough. Fold in the chocolate chips and sprinkles.
4. Cover and refrigerate dough for at least 1 hour, or up to 4 days. Chilling the dough is required in order to avoid the cookie from spreading too much.
5. Preheat oven to 350 degrees.
6. Scoop rounded tablespoons of the cold dough onto an ungreased baking sheet. Shape your cookie dough balls to be "taller" than they are wide. Keep dough chilled when working in batches.
7. Bake for 10-12 minutes until edges are slightly browned. The centers will still appear very soft, but will set as they cool.
8. Allow the cookies to cool on the baking sheet for 4 minutes and transfer to a wire rack to cool completely.
