Easy Variations for Every Craving

How to Make a 2 Ingredient Brownie in a Mug

Yes you can absolutely make a brownies in mug recipe with just two ingredients. It’s not quite as rich as the full version, but it’s perfect when you’re short on time or ingredients.

Here’s what I use:

• 1/2 cup brownie mix (any boxed brand works)
• 3 tablespoons milk (dairy or non-dairy)

Just stir them together in a mug until smooth, then microwave for 60–75 seconds. That’s it. It won’t be as gooey as the full recipe, but it still satisfies the craving.

Want to elevate it? Drop in a few chocolate chips or top with a pinch of sea salt. Even a spoonful of peanut butter or Nutella in the middle makes a huge difference.

For those nights when I want the real deal but fast, I turn to my full 5 minute desserts rich, soft, and bursting with warm chocolate chips in every bite.

Can I Put Brownie Mix in a Mug?

Absolutely and I’ve done it more times than I can count. If I don’t feel like measuring flour or cocoa, I just grab a box of brownie mix and create a shortcut version of my brownies in mug recipe. All you need is:

• 1/4 to 1/2 cup brownie mix
• 2–3 tablespoons water, milk, or coffee
• Optional: 1 tablespoon oil or melted butter for extra richness

Mix it all in a microwave-safe mug and cook it for 60–80 seconds. The texture varies by brand, so keep an eye on it. You’ll know it’s ready when the top is just set and the edges pull slightly from the mug.

I’ve even experimented with protein brownie mixes and added a few extras like nut butter, crushed cookies, or marshmallows. There’s no wrong way to do it just make sure you use a wide enough mug so the brownie cooks evenly.

This trick is also great if you want to keep your pantry clean no half-used bags of flour or cocoa left open. If you’re ever low on milk, don’t worry I’ll be sharing a full mug brownie recipe without milk that works beautifully.

Mug Size, Microwave Tricks, and Foolproof Fudgy Texture

How to Make Mug Brownies That Are Soft and Fudgy

To make the perfect brownies in mug recipe, you need the right balance of ingredients and the right size mug. I’ve tested everything from tiny teacups to soup bowls, and here’s what works:
A 12 to 16 oz mug that’s microwave-safe, with enough room for the batter to rise without overflowing.

Start by mixing all the dry ingredients first sugar, flour, cocoa, and salt to avoid clumps. Then add your wet ingredients: oil (or butter), milk, and vanilla. Stir gently but completely. Make sure to scrape the sides and bottom so everything mixes evenly.

Once the batter is smooth and the chocolate chips are folded in, microwave for 60 to 75 seconds. Don’t go longer on the first try — microwaves vary, and this dessert keeps cooking as it cools. If the top still looks wet after 60 seconds, microwave in 10-second bursts until just set.

Want a richer flavor or deeper cocoa note? Add a small espresso shot next time or take a shortcut with this Espresso Chocolate Mug Cake version.

Can I Make Brownies in the Microwave?

Yes, and it’s one of the best dessert hacks I’ve ever learned. Making brownies in the microwave sounds like it shouldn’t work but it does. Especially when you follow a well-balanced brownies in mug recipe like the one I shared earlier.

The microwave quickly heats the liquids in the batter, causing it to rise and set just like it would in an oven only faster. The key is stopping the cook time before it looks fully done. If the top looks dry but the center is soft, that’s when it’s perfect.

Overcooking is the most common mistake. If your brownie turns out dry or rubbery, it likely cooked too long. Remember: microwave = speed, not precision. Start short and add time in small bursts.

Here’s what I always keep in mind:

• Use a medium or large mug — not too narrow.
• Always rest the brownie 30–60 seconds after cooking.
• Add extra chocolate chips before microwaving — they help retain moisture.

Once you get the hang of it, your brownies in mug recipe will be as reliable as any oven-baked dessert. And much faster.
