In a large bowl, combine butter and both sugars and mix until smooth. Then, you’ll add in one egg at a time, whisking in between. Whisk in the vanilla.
Using a small ice cream scoop or cookie scoop, add 3 scoops of cookie dough into your hand. Shape each one into a giant cookie. You should have about 15 cookies.
Cool the cookies on the baking sheet for 15 minutes before enjoying them. You can then move them to a wire cooling rack to cool completely if you’re not ready to eat them yet!
