Nothing says Happy Birthday like made from scratch birthday sugar cookies with lots and lots of sprinkles! This simple funfetti cookie recipe is fun for all occasions, not just your birthday! Birthday Cake cookies are most certainly the new way to celebrate!
In a small bowl, combine flour, salt, baking powder and baking soda. Whisk to combine and set aside.
In a separate medium bowl, cream together butter, sugar and brown sugar until light and fluffy. This should take about 2-4 minutes. Add in egg and vanilla and beat to incorporate fully.
Slowly add in the dry ingredients into the wet ingredients and beat just to incorporate (do not over mix!) Gently fold in sprinkles. Chill for at least 1 hour for best results. Roll the dough into balls before chilling to make it easy to pop them on the pan.
While cookie dough is chilling, preheat oven to 350°F.
Place cookie dough balls/scoops two inches apart on parchment lined cookie sheet. Bake 9-11 minutes, cookies will be puffed up and may not look 100% done, but pull them just before you think they are done. Allow to cool completely and enjoy. Store in an airtight container for about 3-5 days.
After feedback about cookies coming out too thin, I have adjusted the recipe to include slightly more flour and leavening agents.
