Ingredients

Scale

2 tablespoons unsalted butter, melted
1 tablespoon granulated sugar
1 tablespoon brown sugar, packed
1/4 teaspoon vanilla extract
1 pinch salt
1 egg yolk (discard or save the white for another use)
4 tablespoons all-purpose flour
2 tablespoons chocolate chips

Instructions

In a microwave-safe mug, combine the melted butter, granulated sugar, and brown sugar. Stir until well mixed.
Add the vanilla extract, salt, and egg yolk to the mug. Stir until fully incorporated.
Add the all-purpose flour to the mug and mix until a smooth dough forms.
Fold in the chocolate chips evenly into the dough.
Microwave the mug on high for 40 to 60 seconds. Start checking at 40 seconds to avoid overcooking; the cookie should be set but still soft in the center.
Let the cookie cool for 1 to 2 minutes before eating, as it will be hot.
