đź’ˇ Pro Tips
- Use cold butter – This keeps the cookies thick and bakery-style.
- Weigh your dough – Each should be ~150–175g for even baking.
- Don’t skip freezing – This helps keep them from spreading too much.
- Add toppings before baking – Poking extra chips + cookie bits on top makes them bakery-pretty.
đźš« What to Avoid
- ❌ Overmixing the dough – This can make cookies tough instead of soft and chewy.
- ❌ Skipping the chill step – Without chilling, the cookies may flatten too much.
- ❌ Overbaking – Pull them out when edges are set but centers are slightly soft; they’ll firm up as they cool.
