A sweet and salty single serving chocolate chip cake with a molten chocolate center that comes together (thanks to the microwave) in less than 5 minutes.
Spray a ramekin or microwave safe mug or bowl lightly with non-stick spray. Set aside.
In a small bowl or a measuring cup with a spout, melt the butter by placing it in the microwave on high for 30 seconds. Add the brown and granulated sugars, salt, and vanilla and whisk to combine. Add the egg, and whisk again. Add the flour and whisk again until no clumps remain. Add the chocolate chips and whisk to distribute evenly. You may save half of the chocolate chips to sprinkle on top of your batter so they do not sink to the bottom of the ramekin as easily. Pour this mixture into your prepared ramekin.
Using your fingers, submerge your chocolate square into the center of the batter in the ramekin. Use a spoon or spatula to ensure chocolate square is covered completely. Immediately put ramekin in the microwave and heat on high for 1 minute. The batter will puff up significantly, but it will not bubble over. Carefully remove from the microwave and dig in. Cake is best served immediately and is not meant to be made ahead. Eat right out the ramekin/mug/bowl or flip over onto a plate and serve with a scoop of your favorite ice cream.
