Microwave Timing is Key: Microwaves vary in wattage, so the cooking time is approximate. Start with 60 seconds, and then check every 10-15 seconds until done. You want it just set but still slightly gooey in the center for the best fudgy texture.

Don’t Overmix: Overmixing the batter can lead to a tougher brownie. Stir until the ingredients are just combined. A few lumps are perfectly fine!

Mug Size Matters: Use a standard 10-12 ounce mug. Too small, and it might overflow; too large, and it might spread too thin and cook unevenly.

Ingredient Temperature: For best results, use room temperature milk and oil. This helps the batter come together smoothly.

Make it Vegan: Easily make this mug brownie vegan by substituting the milk with plant-based milk (like almond, soy, or oat milk). The taste and texture will remain wonderfully chocolatey.

Add a Pinch of Espresso Powder: For a richer, more intense chocolate flavor, add a tiny pinch (about 1/8 teaspoon) of espresso powder to the dry ingredients. It enhances the chocolate without making it taste like coffee.

Customize Your Toppings: Get creative with toppings! Besides ice cream, whipped cream, and chocolate sauce, try caramel sauce, chopped nuts, a sprinkle of sea salt, or even a dollop of peanut butter.

Serving Suggestion: For an extra indulgent treat, serve your warm mug brownie with a cold glass of milk or a scoop of your favorite ice cream right in the mug.

Make it Ahead (Dry Mix): To speed up your dessert even more next time, pre-mix the dry ingredients (flour, sugar, cocoa, baking powder, salt) in a small airtight container or zip-top bag. When a craving hits, just add the wet ingredients and microwave!
