INSTRUCTIONS

Step 1:: Cream the butter, sugar, and brown sugar together until light and fluffy (2-4 minutes).
Step 2:: Add the egg and vanilla extract, mixing thoroughly until combined.
Step 3:: In a separate bowl, whisk together the flour, salt, corn starch, and baking soda.
Step 4:: Slowly combine the dry ingredients with the wet mixture until a dough forms.
Step 5:: Gently fold in the rainbow sprinkles.
Step 6:: Roll the dough into 1-1.5 inch balls and chill for 15-30 minutes.
Step 7:: Preheat the oven to 350°F (175°C) while the dough chills.
Step 8:: Place the chilled dough balls on a baking sheet and bake for 9-11 minutes, or until the edges are set but the centers remain soft.
Step 9:: Cool the cookies completely on a rack before serving.

Serving and Storage Tips

These cookies are best served fresh, but can be stored in an airtight container at room temperature for up to 3 days.
If you want to freeze the dough, roll it into balls and freeze on a baking sheet before transferring to a freezer bag. Bake from frozen, adding 1-2 minutes to the baking time.

Helpful Notes

If you want to enhance the birthday cake flavor, try adding a few drops of almond extract along with the vanilla.
For extra chewiness, make sure not to overbake the cookies. Remove them from the oven when the edges are just set but the centers are still soft.
