Ingredients

1 tablespoon unsalted butter 14 grams, melted (⅛ stick)
1 tablespoon granulated sugar 13 grams
1 tablespoon brown sugar 13 grams
1 egg yolk 14 grams
½ teaspoon pure vanilla extract 2 grams
3 tablespoons all-purpose flour 23 grams
⅛ teaspoon kosher salt
2 tablespoons semisweet chocolate chips 21 grams

Instructions

Spray a large microwave-safe mug with nonstick spray. Set aside.
In a small bowl, mix the melted butter, sugars, egg yolk, and vanilla extract together.
1 tablespoon unsalted butter, 1 tablespoon granulated sugar, 1 tablespoon brown sugar, 1 egg yolk, ½ teaspoon pure vanilla extract
Stir in the flour, salt, and almost all of the chocolate chips (leave a few to sprinkle on top of the raw batter). Mix well.

Use a spatula to transfer the dough to the prepared mug.
Sprinkle the remaining chocolate chips on top of the dough.
Microwave on high for 1 minute. The top of the cookie will look set and slightly puffed when done.
Carefully remove the mug from the microwave and let it cool for a few minutes before enjoying. Serve with a scoop of vanilla ice cream, if desired.

Notes

Storage: This chocolate chip mug cookie is best enjoyed fresh and is not meant to be reheated.

Don't overfill your mug, mug cookies can rise a lot more than regular cakes and cookies.
Use a wider mug so the batter cooks evenly through.
Grease the mug well before adding the batter.
Nutritional information does not include ice cream.
