I have a genuine affection for small-batch desserts, and it’s no surprise that my Vanilla Mug Cake, Chocolate Mug Cake, and Nutella Mug Cake have become some of the most sought-after recipes in my repertoire. There’s a certain charm to creating delectable treats in limited quantities. You see, I frequently find myself yearning for a touch of sweetness, but I’m not inclined to embark on a culinary journey that yields an abundance of servings. (Let’s just say that self-control is not my strong suit.)

Whenever I find myself craving an instant dose of indulgence—something rich, fudgy, and oh-so-comforting—I reach for this heavenly Brownie in a Mug recipe. Believe me when I say, it’s ridiculously easy and grants me the pleasure of savoring a warm, gooey brownie within minutes. Yes, you read that right, it takes LESS THAN 5 MINUTES. Can you feel the excitement building? Gah!

Perfecting this recipe was no small feat, let me tell you. Countless variations of Brownie in a Mug recipes populate the vast expanse of the internet, yet none of them ticked all my boxes. I yearned for a brownie that was not only irresistibly fudgy and tender but also bursting with an intense chocolatey essence.

And to top it off, I wanted the entire process contained within a single, trusty mug. No desire to create a pile of dirty dishes for the sake of a single-serving brownie. I am overjoyed to share that my persistence paid off! Brace yourself, because here’s what I concocted…

When it comes to baking petite portions or delightful single-serving recipes, precision in ingredient measurement is of utmost significance. I must mention, however, that the texture of this particular brownie deviates ever so slightly from the beloved norm.

Nevertheless, considering the sheer convenience of concocting a single serving within a mere mug and under the time threshold of 5 minutes, I find no room for complaints. Rest assured, this delectable recipe undeniably satiates even the most fervent brownie hankerings.

Handy tip:

For an extra-rich, extra-decadent, extra-delicious brownie in a cup, try making this recipe with Hershey’s special dark chocolate cocoa powder. If you are a chocoholic, you won’t be disappointed!

Tips For Success

  • When baking, remember every microwave is different. If the brownie hasn’t set after the initial 90 seconds, microwave in 10-second intervals until cooked through.
  • You can use a 12 to 16-ounce mug for this recipe.
  • Don’t overmix the ingredients which will cause the brownie to be tough.
