Preheat oven to 350°F. Line a cookie sheet with parchment paper.
Melt the butter in the microwave and let cool for 10 minutes.
1/4 cup Unsalted butter
In a mixing bowl, mix melted butter, brown sugar, and sugar. Add in vanilla and egg. Mix until smooth.
1/4 cup Brown sugar, 3 TBSP White granulated sugar, 1 tsp Pure vanilla extract, 1 Large egg
Add in flour, baking powder, baking soda, and salt. Use a rubber spatula and fold the dough until just combined. Add in chocolate chips and fold into dough.
3/4 cup Plus 1 1/2 Tablespoons All-purpose flour, 1/4 tsp Baking powder, 1/4 tsp Baking soda, 1/2 tsp Salt, 3/4 cup Semi-sweet chocolate chips
Use a large cookie scoop (I made these using an ice cream scoop). Scoop 6 cookie dough balls and place on the cookie sheet.
Bake for 13-15 minutes. The cookies will be golden brown on the edges. Top with extra chocolate chips. Let the cookies cool on the hot pan for 4 minutes before transferring to a cooling rack.
