Chewy Birthday Cake Sugar Cookies
Preheat the oven to 350 degrees. Line 2 baking sheets with parchment paper. Set aside.
In a large mixing bowl combine the butter and granulated sugar. Use a stand mixer with a paddle attachment or a handheld mixer to beat the butter and sugar together for 7 minutes on medium speed. Do not skip on time. You want the butter and sugar to be thoroughly combined with a very airy, fluffy texture. Scrape down the sides of the bowl. Add in the egg and vanilla extract and continue mixing until combined. Scrape down the sides of the bowl as necessary. Slowly add in the flour, baking soda and salt. Mix the ingredients together on low speed just until combined. Cookie dough will be dry and incredibly fluffy. Add in sprinkles and mix just until the sprinkles are distributed throughout the dough.
Use a cookie dough scoop to scoop out the cookie dough and place it on the baking sheets, giving about 2 inches or more of space between the cookies. These cookies spread while baking so make sure to give them enough room on the baking sheet, I placed 6 balls of dough on each baking sheet.
Bake for 11 to 13 minutes, cookies should be golden brown around the edges, and have crinkles throughout the top. Allow cookies to cool for 5 minutes before transferring them to a cooling rack.
