These homemade lemon crinkle cookies are a perfect blend of tangy and sweet, making them an ideal choice for snack time or special occasions.
In a medium bowl, whisk together flour, cornstarch, baking soda, baking powder and salt. Set aside.
In a bowl of an electric mixer with a paddle attachment (or using a bowl and handheld electric mixer) cream together the butter and sugar for 3 minutes on medium speed.
Add the egg and egg yolk and beat until combined. Scrape down the sides of the bowl with a rubber spatula. Mix in the lemon juice, lemon zest, vanilla, and optional food coloring, mixing for 15 seconds just until incorporated. The mixture will look weirdly curdled at this point.
Cover the bowl with plastic wrap and chill the dough for an hour (or up to 3 hours).
Remove the bowl of dough from the fridge and scoop 1-tablespoonfuls of the dough and roll into balls. If the dough sticks to your hands, spray them with cooking spray to prevent sticking.
Then, roll each ball of dough into the confectioner's sugar. Don’t shake off excess confectioners sugar since it’s better to have more on the cookie than less, since some will melt in the oven.
Place each rolled dough onto the baking sheet, keeping each cookie 2-inches apart. You may need to return leftover cookie dough to the fridge while the first two pans bake, and then continue with prepping a third pan of cookies once they're out of the oven.
Bake the cookies for 10-12 minutes until the edges are slightly golden and the center is puffed and looks slightly underbaked. The cookies will continue to harden and spread a bit as they cool.
Allow cookies to cool on the baking sheet for 10 minutes before transferring to a wire rack to cool completely.
Notes:
● The dough is rolled in granulated sugar first which prevents the butter from turning the
confectioner's sugar a yellow color.
● For a super yellow cookie color, you can add 2 drops of yellow food coloring during step 3 with the eggs.
