½cup(113g) unsalted buttermelted and slightly cooled
¾cup(150g) granulated sugar
¼cup(50g) brown sugar, packed
1large eggroom temperature
1teaspoon(5g) vanilla extract
1 ½cups(180g) all-purpose flour
½teaspoon(3g) baking soda
¼teaspoon(1g) baking powder
½teaspoon(3g) kosher salt
½cup(90g) chocolate chips
Instructions
Preheat oven to 350°Fahrenheit (175°Celsius) and line a baking sheet with parchment paper.
In a large mixing bowl, whisk together the melted butter, granulated sugar, and brown sugar until smooth.
Add the egg and vanilla extract, mixing until fully combined.
Sprinkle in the flour, baking soda, baking powder, and salt. Use a rubber spatula to mix until just combined.
Fold in the mini chocolate chips.
Scoop cookie dough balls (about 1 ½ tablespoons each) onto the prepared baking sheet, spacing them 2 inches apart.
Bake cookies for 9-11 minutes, until the edges are set and the centers look slightly underbaked.
Let baked cookies cool on the cookie sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Use a kitchen scale for the most accurate flour measurement—too much flour makes dry cookies.Slightly underbake for chewy centers; cookies will firm up as they cool.Mini chocolate chips distribute better, but you can use regular chocolate chips if preferred.For thicker cookies, let the dough rest for 5-10 minutes before scooping.
