Did you use melted or soft butter? Did you refrigerate the dough before baking?
We would need to know more about the recipe and what you did while baking to know for sure
https://www.allrecipes.com/recipe/10813/best-chocolate-chip-cookies/ this is the recipe, I used softened butter
It might be too much butter, but I think you're also light on flour. If you're using cups, make sure you scoop it a little over-full and then level it off. You can also try measuring if you have a kitchen scale.
I'll keep that in mind for the future, what's odd is that it was only this particular one that did it, the rest of the batch was fine. For context: these were the last ones out of the bowl
Could have been the butter condensing more towards the bottom of the bowl? Maybe try mixing it up a little bit before scooping out some onto the trays to keep the same consistency in each batch
Just get a scale and weigh your flour. Much more consistent results. 120 grams per cup.
