Soft and fluffy lemon cookies with fun rainbow sprinkles.
Preheat the oven to 350°F. Line a baking sheet with parchment paper.
In a large mixing bowl, add sugar and lemon zest. Use a handheld mixer to combine until lemon zest is fragrant. Add butter and cream together until soft and fluffy. Beat in milk and extracts until combined.
Add flour, cornstarch, cream of tartar, baking powder, and salt. Beat on low until a soft dough forms. Use a wooden spoon or spatula to fold in sprinkles. Chill dough for 25 min.
Use a small cookie scoop to evenly distribute dough on to the prepared baking sheet. Roll into balls and slightly flatten each one down with the palm of your hand. Bake for 10-11 min or until light golden brown.
Allow the cookies to cool for 5 minutes on the baking sheet. Transfer to a wire cooling rack and cool completely before icing.
Prepare the icing: In a mixing bowl, whisk together powdered sugar and lemon juice. Slowly whisk in milk until desired consistency achieved. Top each cookie with a drizzle of icing and dash of sprinkles.
