Preheat oven to 325.
In a large bowl, mix together 1 1/2 cups flour, 1/2 teaspoon each baking powder, baking soda, and sea salt. Whisk together to blend well.
In a medium sized bowl, add 1/2 cup softened butter, 1/2 cup white sugar and 1/3 cup brown or maple sugar. Using a hand mixer, blend until smooth. Add 1 tsp vanilla and 2 eggs. Blend until smooth again.
Add liquid ingredients to the flour mix and mix with your hand blender until thoroughly mixed.
Once smooth, fold in chocolate chips.
Using a spoon, make 2 inch-ish size flat balls and place on your baking sheet.
Bake for 12 minutes. Remove from the oven, use a thin spatula to remove from the sheet and place on a cooling rack.
