Gluten-Free Mug Brownie with coconut sugar - a single-serve brownie recipe made in the microwave

One evening, I had a massive craving for a rich, moist gooey brownie and was 1.) too anxious to wait an entire 40 to 50 minutes to bake a whole batch, and 2.) not interested in the mental and physical aftermath of eating half a 9” x 9” pan of brownies, because I could tell this was one of those moments I had zero ability to moderate.

SO I googled “mug brownie” and found Simply Recipe’s Brownie in a Mug.

And what happened next was beautiful.

I tweaked the recipe to make it gluten-free, refined sugar-free and guaranteed to be fudgy AF (i.e. I added more oil), and what resulted was the most glorious, sexy little brownie I’ve ever laid mouth on.

And I’ve made it multiple times since.

You only need 4 basic ingredients to make this mug brownie!

Ingredients for a Gluten-Free Mug Brownie:

Gluten-free flour blend: I recommend Bob’s Red Mill’s 1-to-1 Gluten-Free Baking Flour or King Arthur’s Gluten-Free Measure for Measure Flour Blend. These will yield a nice and fluffy brownie with that chewy interior and crispy top and sides.

Cocoa powder: Use an unsweetened cocoa powder or raw cacao powder (I use raw cacao powder).

Coconut sugar: Lower on the glycemic index than cane sugar, coconut sugar has a nice caramel flavor and can be used as a 1:1 replacement for cane sugar. I love that it is less refined

Avocado oil: The moist, fudgy quality of this brownie comes from the fat content. You can use canola oil, coconut oil, or melted butter. You can also reduce the fat to 2 tablespoons (and add an extra tablespoon of water)

You will also add sea salt and water, but we won’t count those as actual ingredients 😉

Optional add-ins are ground cinnamon and pure vanilla extract. They certainly aren’t mandatory, but they add a nice little je ne sais quois to the adventure.

I will warn you, this mug brownie is completely addictive. To the extent that when I was photographing it, I initially told myself I would save it for my partner, which turned into oh, I’ll just eat one bite, which turned into me eating the whole thing, save 1 bite for my partner.

Mug Brownie - no eggs, dairy, baking soda, baking powder, or dairy.

So what I’m trying to say is, proceed with caution if caution is in your wheelhouse.

    I hate when people ask if you can substitute ingredients but I’m going to swallow and be one of those people for a second. Forgive me. Is there any Paleo friendly flour I might use? That’s all. K. Now I’m done. They look absolutely delicious!!!!

      LOL no worries at all, Kathy! So I haven’t tested this recipe with any other flour yet, but I’m willing to bet it will work with either Bob’s Red Mill’s Paleo Baking Flour or King Arthur’s Paleo Baking Flour without having to make any other changes to the recipe. Now if you’re fine with a cake-like texture and you eat eggs, you can make my Paleo Chocolate Mug Cake, which uses almond flour. Hope this helps!! If you make it using a Paleo Baking Flour, let me know pleeeeease!! xoxoxo
