In a large, microwave-safe mug, add 1/4 cup chocolate and 3 tbsp of milk. Heat in microwave for about 30 seconds. Stir with a mini whisk to completely melt chocolate into the milk. If chocolate is not completely melted, heat an additional 10 seconds and whisk again.
Add in oil, flour, baking powder. Whisk until batter is smooth. Stir in chopped candy. Cook for approximately 1 minute in the microwave. Allow cake to cool a few minutes before eating. If desired, you can plate in a smaller mug before serving
Notes
Dark chocolate or milk chocolate bars work for this recipe.
I recommend sticking to chocolate-based candy bars.
