My everyday recipe is by Preppy Kitchen. If I have time I like to brown the butter first. The biggest tip though is to let the cookie dough sit in the fridge overnight before baking. I know that sounds impossible but there is science behind it and the difference is huge. Here's Kenji Lopez from the Food Lab's explanation on why:
"An overnight rest allows enzymes to break down large carbohydrates, enhancing the caramelization and browning process the next day to help the cookies develop deeper flavor."
Godspeed good luck on the cookies 🫡
