Step 1

In a large mixing bowl, sift all dry ingredients together.

Step 2

In a separate mixing bowl using a hand mixer, cream butter and sugars together until light and fluffy. Add eggs, one at a time, beating well after each addition. Add vanilla and mix until incorporated.

Step 3

Combine dry and wet ingredients. Don't over mix. Add chocolate chips. Cover with plastic wrap and allow to sit in the fridge overnight, or up to 3 days.

Step 4

When ready to bake, preheat oven to 350F*. To get the cookies just the right size, use a standard cookie scooper - then divide that amount in half. Place cookie dough balls evenly onto a baking sheet. Bake for 8 to 10 minutes, or until barely done. You want to under-baked these cookies slightly so they turn out soft and gooey.

Step 5

*Some readers reported better results baking the cookies at 375F instead of 350F. This results in a cookie that is more crispy on the outside with a slightly soft center.
