Ingredients

Scale

2 tablespoons Dutch process cocoa powder
2 tablespoons all-purpose flour
2 tablespoons granulated white sugar
1 1/2 tablespoons vegetable, canola, or mild olive oil
2 tablespoons water
1 tablespoon chopped dark chocolate, plus extra for topping

Instructions

Combine the dry ingredients: In a microwave-safe mug or ramekin with a capacity of at least 8–10 ounces, combine the cocoa powder, all-purpose flour, and granulated sugar. Stir with a fork until evenly mixed and free of lumps.
Add the wet ingredients: Pour in the oil and water. Stir thoroughly until a smooth, thick brownie batter forms, scraping the bottom and sides of the mug.
Add the chocolate: Fold in the chopped dark chocolate. Sprinkle a few extra chocolate pieces over the top for an extra-rich finish.
Microwave the brownie: Cook on high power for 45–60 seconds. Start checking at 45 seconds, as microwave wattages vary. The brownie should look set around the edges while remaining slightly soft in the center.
Let it rest: Carefully remove the hot mug from the microwave and allow the brownie to rest for 2 minutes. This helps the center set while keeping the texture soft and fudgy.
Serve and enjoy: Eat warm straight from the mug. For an extra-indulgent dessert, add vanilla ice cream, whipped cream, powdered sugar, or a drizzle of peanut butter.

Notes

Avoid overcooking: Start with 45 seconds and add 5–10-second intervals if needed. The brownie continues to set as it rests.
Choose Dutch process cocoa: It provides a deep chocolate color and smooth, rich flavor.
Try a milk substitution: Replace the water with an equal amount of dairy or unsweetened almond milk for a slightly richer taste.
Use chocolate chips: Substitute semi-sweet or dark chocolate chips for the chopped chocolate in equal amounts.
Make it nutty: Swirl 1 teaspoon of peanut butter or almond butter into the batter before cooking.
Serve immediately: Mug brownies taste best warm and fresh. This recipe is designed for immediate enjoyment rather than storage.
Microwave safety: Use only a microwave-safe mug or ramekin and handle it carefully after cooking.
