1. In a separate bowl, whisk together milk, oil, egg, and vanilla extract.
2. Pour the wet ingredients into the dry ingredients and mix until just combined.
3. Fold in the melted chocolate, ensuring an even distribution.

2. Bake the Muffins:

1. Line a muffin tin with paper liners.
2. Fill each liner 2/3 full with the batter.
3. Bake in the oven for 3 minutes if using a microwave or 12-15 minutes in a conventional oven.
4. Insert a toothpick into the center of a muffin—if it comes out clean, they’re done.

3. Cool and Serve:

1. Let the muffins cool for 2-3 minutes before serving.
2. Enjoy warm for gooey chocolate or let them cool for a firmer texture.
