1 tbsp salted butter or use unsalted butter but add a pinch of salt to the recipe
2 tbsp semi sweet chocolate chips
1 egg yolk
1 tbsp brown sugar & 1 teaspoon brown sugar

First, start by melting the butter in the mug in the microwave. Add in the chocolate chips and stir until completely melted. Microwave the mixture as needed until the chocolate is completely melted.
1 tbsp salted butter, 2 tbsp semi sweet chocolate chips
Add in the egg yolk, the brown sugar, and the vanilla if you're using some and stir until incorporated, Add in the flour and stir one more time just until the flour disappears. At this point you can add the chocolate chips and gently stir to get them incorporated to skip this step.
1 egg yolk, 1 tbsp brown sugar & 1 teaspoon brown sugar, 1/8 tsp vanilla, 2 tbsp flour, 1 tbsp chocolate chips
Cook the brownie on high in the microwave for 45 seconds. Microwave temperatures vary so you can cook it for an additional 15 seconds if necessary.

The nutritional value was calculated without the added chocolate chips in the batter because I didn't add them to the recipe that I shot.

This mug brownie recipe is best eaten as soon as you make it because it tends to harden as it sits.
