These mini sugar cookies are uber soft, uber chewy, and have a gorgeous sparkly coating. With just a few basic ingredients, you'll end up with nearly 100 mini cookies for a crowd. Leave them as-is or roll the dough in colorful sanding sugar for holidays like Christmas, Halloween, and Valentine's Day. They're the best!
Whisk together the all purpose flour, cornstarch, baking soda, and Kosher salt in a small mixing bowl. Set aside.
Then, add the softened unsalted butter and 150 grams (3/4 cup) of the granulated sugar to a large mixing bowl. Using a hand mixer or stand mixer, beat the butter and sugar until it's light and fluffy, about 2-3 minutes. Then, mix in the egg and vanilla bean paste or extract until the mixture is smooth.
Pour the flour mixture into the wet ingredients. Beat the dough just until there are no more streaks of flour. Cover the dough and chill for at least 1-2 hours, or overnight.
When you're ready to bake the cookies, preheat the oven to 350°F (177°C). Line 2 sheet pans with parchment paper. Then, place the remaining 100 grams (1/2 cup) of granulated sugar in a shallow bowl.
Using a #100 cookie scoop or teaspoon, scoop the dough into balls. Roll the cookie dough balls in the granulated sugar. Then, line the cookie dough balls about 1 inch apart on the prepared sheet pans. Refrigerate any leftover dough while the cookies are baking.
Bake the cookies for 5-6 minutes, just until the edges are set and the centers are still a bit under-done. Don't over-bake or the cookies will end up crunchy! Let the cookies cool on the sheet pans for 4-5 minutes and then transfer them to a wire rack to cool completely. Enjoy!
Notes
For soft and chewy cookies, I recommend weighing the ingredients instead of using measuring cups. If you do not have a kitchen scale, here's how to measure the flour. First, fluff it with a whisk and spoon the whisked flour into a measuring cup. Level it off without packing the flour in.If the dough is too cold to scoop, let it warm at room temperature for 20-30 minutes. You want it to be chilled but still scoop-able.The cookies are ready when they are puffed up but not browning. They should be set on the edges and a tad under-baked in the middles.For super round cookies, use the scoot method! Right after the cookies come out of the oven, place a small round cookie cutter or cup around each cookie and scoot it in a circular motion to round out the edges.Feel free to roll the cookies in colorful sanding sugar for holidays. Just replace the 100 grams (1/2 cup) of granulated sugar with whatever color sanding sugar you'd like. Try red and green for Christmas, black and orange for Halloween, etc.
