Why are you calling them “juicy”?
I mean that soft, moist, tender center that feels rich, not dry. It is the same idea as a juicy brownie, not a literal liquid cookie situation.
Can I skip chilling the dough?
Yes. They will spread a little more and bake a bit thinner. If you want thicker cookies with a softer center, chill for 20 to 30 minutes, even if it is just while the oven preheats and you clean up.
How do I make them thicker?
Chill the dough, use a slightly taller scoop, and do not flatten the dough balls. Also make sure your baking sheet is cool before adding new dough.
Why did my cookies turn out flat and greasy?
Most common reasons: butter was hot (not just melted), dough was not chilled, baking sheet was warm, or your flour was under-measured. Let the butter cool until just warm, and spoon and level your flour.
Why are my cookies dry?
Usually they were overbaked by a minute or two, or the flour was packed into the cup. Pull them when the edges are set and lightly golden but the centers still look a little underdone. They finish as they cool.
Why are the bottoms too dark?
Dark baking sheets brown faster. Use a lighter colored sheet, double up two sheets, or move the pan to a higher rack position. Parchment also helps.
Can I use chocolate chunks instead of chips?
Absolutely. Chunks melt into puddles. Chips hold their shape more. A mix of both is elite.
Can I make these gluten-free?
You can try a 1:1 gluten-free baking flour blend. Texture will vary by brand. Chill the dough and expect slightly more spread.
Is it safe to eat the raw dough?
Raw flour and raw eggs can carry bacteria. If you want to snack on dough, consider using heat-treated flour and skipping the egg (or use a trusted egg-free edible cookie dough recipe).
