These cookies are the best.  They stay  chewy for days!  Tell me about your experience with them!

Ingredients
2 cups all-purpose flour
2 tablespoons all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon salt
12 tablespoons unsalted butter, melted and cooled until warm
1 cup packed brown sugar (light or dark)
1/2 cup granulated sugar
1 large egg
1 large egg yolk
2 teaspoons vanilla extract
1 1/2 cups chocolate chips

Directions
1. Place oven racks in the upper and lower 1/3′s of the oven.
2. Preheat oven to 325
3. put parchment paper on cookie sheets (this keeps the cookies from sticking)
4. Mix butter and sugars with with a mixer until blended and smooth, add egg, yolk & vanilla.
5. Mix until incorporated.
6. Add dry ingredients and mix until just combined.
7. Stir in chips and optional nuts.
8. Divide into 18 equal balls, a 2′ cookie scoop works just about perfectly, about 60 gms each.
9. EVENLY space 9 on each cookie sheet.
10. Bake for 12-18 minutes, rotating front to back and top to bottom after 8 minutes. (I typically go for 12 minutes, 8 minutes on the top rack, then rotate and move down to the bottom rack for 4)
11. Cool on sheets to maintain chewy texture.
