Can I double the recipe for two servings?

Yes! You can double the ingredients, but it’s better to use two separate mugs instead of one large one. This ensures your microwave brownies in a mug cook evenly and don’t overflow.

How do I know when my 5 minute brownie is done?

Check the edges first—they should look set while the center remains slightly soft. That gooey middle will firm up as it cools. Overcooking is the main reason a 5 minute brownie turns dry, so stop the microwave as soon as it looks mostly done.

Can I make quick mug brownies dairy-free?

Absolutely! Substitute almond, oat, or soy milk for dairy milk, and use oil or vegan butter in place of regular butter. These swaps still give you fudgy, rich quick mug brownies with no compromise on flavor.
