Preheat the oven to 350°F (180°C).
In the bowl of a stand mixer or with an electric mixer, cream together the butter, brown sugar, and granulated sugar until light and fluffy.
10 Tbsp salted butter, softened, 2/3 cup (163g) brown sugar, 1/2 cup (115g) granulated sugar
Scrape the sides of the bowl and then add in the egg and vanilla. Mix until incorporated.
1 egg, 1 tsp vanilla
Next, add the flour, baking soda, baking powder, and salt. Mix until a soft dough forms.
1 3/4 cup (266g) all-purpose flour, 1/2 tsp baking soda, 1/2 tsp baking powder, 1/2 tsp salt
To the dough, fold in the finely chopped chocolate chips.
1 1/2 cups (300g) chocolate chips, finely chopped
Portion the dough out into small, 1/4-1/2 tsp balls. I find it easiest to use a rolling pin and roll the dough out, freeze for 10 minutes and then cut into small squares. Take each square and roll it into a ball and arrange on parchment lined cookie sheets.
Bake at 350°F (180•C) for 8-10 minutes or until golden brown.
Allow the cookies to cool on the pan completely. Serve with a bowl of milk and enjoy! :)
These can be stored in an airtight container for up to 4 days.
