Instructions
1
In a large bowl, using an electric handheld mixer, beat the softened butter and sugar for 30 seconds, starting on low speed and increasing to high speed as the mixture comes together. Add the egg, egg yolk and vanilla and beat on high speed until fluffy.
2
Add the flour, cornstarch, baking soda, and cream of tartar and mix on low speed just until combined. Cover the bowl of cookie dough and refrigerate for 1 hour.
3
A few minutes before the dough is done chilling, preheat the oven to 350℉ and line baking sheet(s) with parchment paper or silicone baking mats.
4
Remove the dough from the refrigerator and roll it into balls about 1 inch in diameter. Roll each ball in the extra white sugar or coloured sanding sugar to coat. Place 8 cookie dough balls on each pan, leaving about 2 inches of room between each cookie for spreading during baking.
5
Bake the cookies in the preheated oven for 8-11 minutes (I found 11 minutes was perfect in my oven, but every oven is different!) or until puffy and no longer wet-looking on top. Let cool for 5 minutes on the baking sheets before transferring to a wire rack to finish cooling. Bake the remaining cookies. Enjoy!

Tips & Tricks (5)
- Room Temperature Ingredients 🌡️Bring butter and eggs to room temperature before mixing to ensure proper emulsification and create a uniform dough that bakes evenly with the perfect chewy texture.
- Cream of Tartar Secret 🥄The cream of tartar is essential for chewy cookies—it reacts with baking soda to create lift while maintaining moisture, so don't skip it or substitute it.
- Cornstarch for Chewiness ✨The cornstarch reduces gluten development and adds tender chewiness to the center; use cornstarch that's completely dissolved in your dry ingredients for best results.
- Strategic Sugar Coating Timing 🍪Roll warm cookies in sanding sugar immediately after baking while they're still tacky—this helps the sugar adhere and creates a beautiful, sparkling crust.
- Slightly Underbake for Perfect Texture 👌Remove cookies when the edges are set but the centers still look slightly underdone—they'll continue cooking on the hot pan and develop that signature chewy center you want.
