Once they're out of the oven, let the cookies chill on the baking sheets for about 5 minutes. Move them gently to cooling racks. Sprinkle on sea salt right away while they're still warm.

Put one tray in the center of your oven and bake till the edges are golden brown and the tops aren't wet anymore. Regular-sized ones take 8 to 10 minutes, bigger ones need 10 to 13.

Use a big spoon or ice cream scoop to drop dough on your lined sheets. Leave plenty of room, about 6 to 8 scoops to a tray, depending on how big they are. For fun, press some more chips on top if you’re feeling fancy.

Gently mix in butterscotch chips, chocolate chips, and walnuts if you’re using them, just long enough so they're spread out evenly.

Dump in the flour, then toss in the baking soda and salt. On low speed, blend until they're just mixed in. Don't keep going, or the dough gets tough.

Throw in your egg and vanilla. Use low speed and mix until it all looks even.

Switch your oven on to 175°C. Put parchment on two baking sheets. That way, cookies won't stick.
