How to Make a Brownie in a Mug

This ooey gooey peanut butter brownie in a mug recipe is absolutely amazing!! Throw it all together, stick in the microwave for 1 min. and it’s done to perfection! Dessert for one has never been more delicious and easy.

Brownie Mug Recipe

This brownie mug recipe is quite simple and perfect for a chocolate craving. Sometimes you just want a single serving of yum, not to make a whole pan full. We love peanut butter inside. Of course you can add other goodies too if you want.

This is just one baking hack we figured out when I wanted a late night snack but not make an entire batch. A single serving brownie was just what I needed that night. I had made brownies out of cake mix so I knew I could make it other ways than in a square pan, it was time to experiment and figure this out.

Peanut Butter Brownie in a Mug

I didn’t just stop there, I thought adding a bit of hidden peanut butter in the center would be amazing too. That is a must in our house and we always have a few jars in the pantry. Yes you can omit it if there’s an allergy, and it is still tastes amazing.

• You don’t have to add peanut butter brownie in a mug, but this addition is delicious!

If you have a sweet tooth but don’t want to make an entire package of brownies or cake this is a great alternative dessert for one! My girls will make this as a quick treat for themselves after school and I am guilty of making one late at night when we are watching movies on the weekend. 😉

Brownie in a Mug No Egg No Milk

If you have allergies this type of mug cake is a great one. It is eggless and dairy free! I know, killer right?? Perfect for my husband who can no longer have either. I start with I looked at the recipe from Simply Recipes because it is easy and I had everything in my cupboard at home. From there I changed a few things and added peanut butter and it came out amazing!

I’m all about easy and ooey gooey desserts so I’ve made this one often because it’s just so easy and hits the spot when I want something sweet.

• I decided to add a dollop of peanut butter in the center but you could also add a few Rollo caramels or leave it all out. 
• A “regular” microwave brownie in a mug which is amazing as well.

How to make a brownie in a mug

I’m a peanut butter fanatic so if I am really going to go all in and indulge myself when making a microwave dessert for one I am going to really go for it if you know what I mean.

Brownie in a Mug No Egg

Make sure you measure flour properly when measuring ingredients for this single serving brownie recipe. What that means is that you need to fluff it, scoop with a spoon when measuring and don’t pack it down. If you do it will become much more dense and not rise properly.

1. Cocoa powder
2. Sugar
3. Flour
4. Salt
5. Oil – vegetable or olive oil if that’s all you have, could use melted butter if necessary
6. Vanilla extract
7. Peanut butter (optional, great without it too)
8. medium/large microwave safe mug so it doesn’t overflow

The reason why you need a mug a bit larger than a standard tea or coffee cup is it may overflow. Cooking time is short because it is just one (or two) serving really. If you’re looking for a dessert with no eggs necessary, this is the one to make!

If you wanted to substitute something else in the center you could use a pinch of chocolate chips instead into the center or 1 tsp of crushed nuts. I like to keep my baked goods very tender so I don’t like crunchy bites inside myself. I would suggest making it as is directed below and go from there. Compare with and without the add ins and see which is your favorite bites.

How do you make microwave treats?

I mean it is really easy, and doesn’t heat up your entire house in the process. This one takes about 10 minutes to prep or so. If you need a simple 2 ingredient microwave treat this is how to make a mug cake with cake mix too.

• A dollop of whipped cream of vanilla ice cream on top can be added too.
• It’s pretty darn sweet though so I would first try as is. It’s to die for!

If you love this easy brownie in a mug recipe you could put together the dry ingredients in small baggies.

• Then use another “batch” on other nights.
• Write with a sharpie on the bag what wet ingredients you need so it’s quick when you’re ready to make it again.

Seriously, it is so easy that way. Just make a large batch of this brownie in a mug mixture but portioned out into ziplocs so it’s ready when you are.

Can you reheat a mug cake?

Well to be honest I have never not finished the entire thing on the first go around. If I don’t my husband will finish it off but I suppose you could cover with plastic wrap and then microwave for 10 seconds for the next go around.
