I'm leaving for Hawaii in 3 days, which means that I can't bake anything large.
Why is that you ask? Well, I learned my lesson two years ago when I left for 2 weeks to go camping. I made some delicious Lemon Muffins before I left. I brought some camping, but left the remaining in a container right in the middle of the kitchen, where I was hoping people in my house would see and eat.
But what happens when I get back? The container is now green and climbing with mold, and none of my muffins were touched! The thing with people in my house is that they will resist sweet things or desserts unless they are offered. Seriously, the self control on these people.
So I'm making another personal-sized dessert in a mug. Because I certainly don't need an invitation to have dessert. It seems to be a way of life for me. Also having a brownie ready in front of you in less than 5 minutes is definitely my idea of a good time.
Key Ingredients
- Flour: Gives the brownie its structure, holding all the wet ingredients together.
- Sweetener: Both white sugar and brown sugar are used to add sweetness, with the brown sugar giving it a more caramel-like richness that mimics brownies.
- Butter: Gives the brownie its rich and moist texture.
- Cocoa powder: Used to give the brownie its main rich chocolate base flavor.
- Egg yolk: Makes the brownie dense and fudgy, and gives the brownie its structure.
- Vanilla: Enhances the chocolate flavor, and rounds out the overall sweetness.
- Salt: Amplifies all the other flavors. Never skip the salt!
- Chocolate chips: Melts into gooey pockets of chocolate throughout
How To Make Microwave Brownie in a Cup
Step 1: Melt the butter in a microwave safe mug for 10-20 seconds, or until all the butter lumps are gone.
Step 2: Mix in the sugars, vanilla, salt, egg yolk, flour and cocoa powder until combined. Fold in the chocolate chips and microwave for 45 seconds.
Microwave Brownie in a Cup Expert Tips
Adjust the amount of sugar to your liking. I personally love a very sweet brownie, but you can reduce the sugar if you want it less sweet since it does also have chocolate chips in it.
Make sure you use a standard 10 to 12 oz mug. Do not use bowls or very large bottomed mugs, as the batter will spread out thin, causing the brownie to overcook.
Allow the brownie to cool. While it is so tempting to eat the brownie right away, let it cool for 1-2 minutes before eating. The center is very hot right out of the microwave, and letting it rest helps the texture firm up.
Customize your mix-ins. Instead of chocolate chips, try chopped walnuts, M&Ms, or your favorite mix-ins.

Microwave Brownie in a Cup
Ingredients
- 2 Tbsps unsalted butter
- 2 Tbsps granulated sugar
- 1 tablespoon brown sugar, packed
- ¼ teaspoon pure vanilla extract
- pinch of salt
- 1 large egg yolk
- ¼ cup all-purpose flour
- 1 tablespoon unsweetened cocoa powder
- 2 Tbsps chocolate chips
Instructions
- Melt the butter in a microwave safe mug for around 10-20 seconds.
- Mix in the sugars, vanilla and salt with the melted butter. Stir in the egg yolk until fully combined.
- Add in the flour and cocoa powder, and mix until fully incorporated. The batter should be thick. Fold in the chocolate chips.
- Place in the microwave, and microwave for around 45 seconds.
Notes
- Allow the brownie to cool. This allows the texture to firm up more, as the brownie continues cooking after taking it out of the microwave.
- Swap out the chocolate chips. Use your favorite mix-ins! My favorite swap is either M&Ms or chopped walnuts.
- Make sure you use a standard coffee mug. A standard 10-12 oz mug works best. Avoid using bowls or wide bottomed coffee mugs, since the batter will spread out thin on the bottom and get overcooked.
- Adjust the sweetness. Feel free to slightly reduce the sugar if you prefer a less sweet brownie, especially since the chocolate chips add extra sweetness.
BRILLIANNTTTTT. Definitely a handy one for 'emergencies'.
Aloha! I love these when my husband is gone and I can make my own and not have leftovers!
I love super easy brownies in a mug! Perfect for a night alone in front of the t.v. 🙂 Also, can't wait to hear about your Hawaii trip. My hubby and I went there on our honeymoon and absolutely loved it!
Heavenly, my idea of comfort food!
I feel like it's the opposite here...if I leave ANYTHING in this apartment, the.boy will eat it before I get back. Even if I'm only gone for a day!
Love the sound of these brownies in a mug though!
My family sometimes does that too. They don`t know if they can eat my baked goods! LOL.
So jealous of Hawaii!
Those muffins wouldn't have lasted in our house -- in invitation needed! Love this brownie recipe, though -- perfect for those of us who have no self control! Have a great trip.
This looks great, and I bet just the smell of it is fantastically chocolatey! 🙂
Have an amazing time in Hawaii ^ ^ x
