Soft, thick cookies with crinkly tops and golden edges. Melted butter, two egg yolks, and a little cream cheese make a one-bowl, no-chill dough that stays soft for days.
Switch to a spatula. Add the flour, cornstarch, baking soda, and salt. Fold gently just until no dry flour remains. Do not overmix.
1¾ cups all-purpose flour, 1 teaspoon cornstarch, 1 teaspoon baking soda, ½ teaspoon salt
Stir in the chocolate chips or chunks, reserving a handful to press on top after baking.
1½ cups chocolate chips or chunks
Scoop 3 tablespoons of dough per cookie. Space them well apart: 4 cookies on a standard half sheet, or 6 to 8 on a large sheet.
Bake one pan at a time for 10 to 11 minutes, until the edges are set and lightly golden and the centers still look slightly soft and puffy.
Press extra chocolate on top right away (highly recommended) and sprinkle with flaky salt if using.
Let the cookies cool on the pan for 15 minutes before carefully moving them to a wire rack.

Notes
Bake time is per pan. A standard half sheet fits 4 cookies and a large sheet fits 6 to 8. Bake one pan at a time on the middle rack, and keep the next batch of scooped dough on the counter while you wait.
Weigh it for foolproof cookies. Every ingredient has a gram weight in the Metric tab. Flour matters most: 220 g. Scooped flour is the number one reason these come out thick and dry.
Make ahead. Refrigerate the dough up to 24 hours, or freeze scooped dough balls up to 3 months and bake from frozen, adding 1 to 2 minutes.
Parchment vs. silicone mats. Parchment gives a wider, flatter cookie. Silicone mats give a slightly thicker one. Both work, it's preference.
Chocolate on top = better shape. Pressing extra chips or chunks on right after baking helps the cookies settle and flatten evenly as they cool.
For perfectly round cookies. While they're still warm, place a round cookie cutter slightly larger than the cookie around it and gently swirl.
Cooling matters. These keep setting as they cool. Leave them on the baking sheet for at least 15 minutes before moving.
