Instructions
- Lightly spray the bottom of a microwave-safe mug with cooking spray.
- Add the flour, sugar, cocoa powder, baking powder, and salt. Stir to combine.
- Pour in the milk, oil (or melted butter), and vanilla extract. Mix well until smooth, making sure to scrape the bottom of the mug.

Tips
- Cooking time varies by microwave—start with 70 seconds and add more if needed.
- Use a large mug (at least 12 oz) to prevent overflow.
- Mix the batter thoroughly so no dry spots remain.
- Let the cake rest before eating—it will continue to set as it cools.
Variations and Substitutions
- Flour alternatives: Try almond flour or gluten-free flour for dietary needs.
- Flavor twist: Add a pinch of cinnamon, espresso powder, or a drop of peppermint extract.
- Mix-ins: Use white chocolate chips, peanut butter chips, or chopped nuts.
- Toppings: Finish with whipped cream, ice cream, or a drizzle of caramel sauce.
