Ultra fudgy flourless brownie in a mug that’s cooked in just 1 minute! It’s a paleo and grain free easy microwave brownie recipe that tastes so decadent.

Question: does it defeat the purpose of a microwaved mug dessert if you make it twice a day, everyday? ASKING FOR A FRIEND. They are just too easy to make, so fun to eat out of a mug, and you can’t beat how dangerously quick they are to make. I made this flourless mug brownie several times already this week because it’s that good!

Flourless Brownie in a Mug Recipe

I almost called this microwave mug brownie recipe “paleo chocolate mug cake” or “flourless chocolate mug cake.” However, the texture turned out fudgier and slightly denser than cake. After tasting it multiple times (I couldn’t stop), I realized that that it was definitely a brownie and a very good one! It’s just so amazing and the single serving size is so perfect for IMMEDIATELY fulfilling your chocolate cravings.

How to Make Paleo Mug Brownie

The instructions for this microwave mug brownie recipe is so simple and easy:

  1. Combine all ingredients and whisk together until smooth.
  2. Grease the inside of your favorite mug, and pour the batter in.
  3. Microwave for 60-90 seconds.
  4. Cool for 5 minutes before digging in! You can top with your favorite toppings if you’d like.

The microwaving time depends on how wide your mug is and the power of your microwave. This flourless mug brownie is ready when the center is still slightly jiggly and that’s what make it so fudgy. I would check after 60 seconds in the microwave, then add more time if it needs to be cooked more.

Ways to Enjoy This Easy Microwave Brownie Recipe

This easy microwave brownie recipe will yield 1 large serving, but you can definitely stretch it to 2 servings because it’s rich and so satisfying. This is especially true if you are serving it with optional add-ons to stretch it even further. Here are some ideas on ways to enjoy this paleo mug brownie:

  • with vanilla ice cream
  • with whipped cream or whipped coconut cream
  • topped with chocolate chips (I love these dairy free ones) or shaved chocolate flakes
  • sprinkled with powdered sugar
  • topped with fruits like berries
  • drizzled with chocolate syrup or caramel sauce
  • drizzled with nut butter
  • topped with chopped nuts

Whether you want to call this a flourless mug brownie or flourless chocolate mug cake, it’s so tasty and wonderful. There’s honestly nothing like digging your spoon into a warm and fudgy chocolatey goodness!

    Just made this 30 minutes ago….so good! Do you think I can add some flax and brewer’s yeast to help with lactation?

      It might dry it out a bit but I think it’ll still work!

    Looks so good! Is there any way to make this without eggs? Would a flax egg work as a substitute?

      No, it won’t work. You need the egg to help it rise. A flax egg doesn’t allow it to do that.

    It’s delicious! Thanks so much for this recipe!
    -can I omit the egg yolk and use only egg white?
    – can honey be used instead of syrup? Or a raspberry fruit sweetened jam?
    Thank you!

      I’ve never tried with just egg whites but I’m not sure if it’ll rise the same. And yes, you can definitely use honey or other liquid sweeteners!
