Brazil Nut Brownies

Dietary Compliance: Gluten-free, Dairy and Soy-free depending on chocolate used

When I set out to create a Brazil nut brownie recipe, I had ulterior motives. I was trying to find an enjoyable way to eat what used to be my least favorite nut. My motivation came from the knowledge that Brazil nuts are a thyroid superfood, and blow any other food out of the water when it comes to selenium content. Nothing comes close, and just one a day may exceed the recommended daily value (though be aware, selenium content in Brazil nuts can vary widely).

In looking up food pairings for Brazil nuts, chocolate, coconut, and vanilla topped the list. Brownies seemed like a perfect excuse to get those Brazil nuts down, no problem.

Brazil Nut Brownies

With a crackly top and crisp-chewy edges, these decadent, ultra-fudgy, brownies are the stuff chocolate dreams are made of. They also happen to be gluten-free and if you use chocolate that is free of soy lecithin and milk solids, they’re dairy and soy-free, too.

An added bonus, at least in my opinion, is the 8×8-inch pan. I mean, 9×13?  Who on earth is going to eat all that?

I am. That’s the problem.

Recipe Notes

To remove the seeds from a vanilla bean, lay the bean on a cutting surface, and with the tip of a paring knife, split the bean lengthwise all the way down the middle. Use the dull side of the knife to scrape along the inside of the pod, removing the sticky, tiny, black vanilla seeds. Repeat with the other half of the pod.
