Review RecipeBrownie in a Mug

Table of Contents
This delicious brownie in a mug recipe is just the thing to satisfy any chocolate cravings. Instead of baking a whole pan of brownies, now you can make just one perfect little brownie in a mug with hardly any cleanup required.

Brownie in a Mug Ingredients

You’ll need:
- 3 tablespoons all-purpose flour
- 3 tablespoons Dutch-process cocoa powder
- 3 tablespoons brown sugar
- Pinch of salt
- ¼ teaspoon vanilla extract
- 3 tablespoons milk
- 3 tablespoons vegetable oil
- 2 tablespoons chocolate chunks or chips
- 1 tablespoon beaten egg (see notes)
PRO TIP:
If you want a larger serving of this fudgy chocolate brownie, make it in a separate mug. Do not increase the amounts in this recipe. Simply Increasing the quantities will not give you the same delicious result without significant adjustment to the recipe and cook time.
SUBSTITUTIONS AND ADDITIONS
MIX-INS: You can use any type of chocolate chip (or chip alternative – peanut butter chips, white chocolate chips, nuts, etc.) that you’d like instead of the chocolate chunks for this single-serving brownie.
How to Make This Brownie in a Mug Recipe
OUR RECIPE DEVELOPER SAYS
The brownie batter ingredients can be made right in the mug itself. I like to stir the dry ingredients together first to make sure they’re well combined. Then mix in the wet ingredients.
STEP ONE: Stir together the dry ingredients in a 6 to 8-ounce microwave-safe mug.
PRO TIP:
Brownie in a mug does not rise much; just a little bit. I recommend a 6 to 8-ounce mug. Depending on your mug’s shape/size, the brownie may not come up to the top edge but will still taste delicious.

STEP TWO: In a separate bowl, use a fork or small whisk to thoroughly beat one egg. Measure 1 tablespoon of the beaten egg and add it to the mug.
PRO TIP:
The egg in the recipe adds some leavening and makes a chewier brownie. You wouldn’t think a tablespoon of egg could make a difference in your mug cake, but it does! Of course, you can skip this ingredient, and you will still have a nice brownie in a mug, but if you can, add in the egg. You can make about 3 recipes from one egg.

STEP THREE: Add vanilla, milk, and vegetable oil to the mug and stir to make a batter. Mix in ½ of the chocolate chunks and sprinkle the other half over the top.

STEP FOUR: Microwave mug brownie for 1 minute to 1 minute 15 seconds. The mug cake is done when it no longer appears wet across the top.

How To Serve
Enjoy this mug filled with an ooey gooey brownie along with a scoop of vanilla ice cream or cookies and cream ice cream to make it an even more indulgent treat. Make a second mug to share with a friend.
Our vanilla mug cake and chocolate mug cake are two more delicious variations of this easy recipe.

FREQUENTLY ASKED QUESTIONS
This easy chocolate brownie does not reheat well, and we don’t recommend trying to store it in the freezer for any length of time.
A 6 to 8-ounce mug is just the right size for this great recipe.
The cooking time will depend on the wattage of your microwave, but we find somewhere between 60 to 75 seconds is about right. Keep an eye on your cake near the end of cooking and watch for the center to be just set. Don’t overcook it, or you will end up with a dry cake.
