• Preheat oven to 375°.
• Mix the butter with the sugars until creamy. Add vanilla and eggs and mix well.
• Add flour, baking soda, and salt and mix until combined. Stir in chocolate chips.
• Drop by spoonfuls onto a baking sheet (I highly recommend using parchment paper to line your baking sheet.)
• Bake for 8-10 minutes, until lightly browned on the edges. Remove from baking sheet carefully to cool. Repeat with the remaining dough.

For high altitude:

• Reduce sugars to ⅔ cups each. Increase flour to 2 ½ cups. Add 2 tsp. water with the flour.
