How These Brownies Accidentally Became Flourless

My original recipe had 1 tablespoon of cassava flour. One day I was halfway through baking when I realized I’d forgotten the flour completely. I braced myself for a pan of chocolatey sweet potato mush.

Instead, they baked into the fudgiest, gooiest brownies I’d ever made. I haven’t added flour since! The sweet potato and almond butter give them body, and the eggs hold everything together. You get soft centers, chewy edges, and that crackly top.

Before You Start

  • Measure 1 1/2 cups of sweet potato after mashing.
  • Your sweet potato shouldn’t be watery. If you boil it, drain it really well. Steaming is even better.
  • Short on time? Canned sweet potato purée works.
  • Pull the pan a few minutes early for the gooiest center.
  • Let them cool for 10 minutes before cutting so the squares hold their shape.

Best Sweet Potatoes for Brownies

You’d be surprised how many kinds of sweet potatoes are out there. After testing a few, here are my top three:

  • Japanese sweet potatoes: red skin, white flesh, super creamy, and naturally sweet. My absolute favorite. I always have some on hand.
  • White sweet potatoes: creamy and sweet like Japanese ones, with super thin skin. Harder to find, but worth grabbing if you spot them at a store like Whole Foods.
  • Regular orange sweet potatoes: the easiest to find. Cut off both ends to cut down on stringiness. Not my favorite of the bunch, but still good!

Bought too many? Roast the extras into my maple miso glazed sweet potatoes or stir them into a big pot of sweet potato chili.

Can I Use a Different Nut Butter?

Yes! Smooth almond butter makes the gooiest brownies, but chunky works too if you like a little crunch. I’ve tested both, and you can’t go wrong. Out of almond butter? Peanut butter is delicious here too.

Steam or boil the sweet potatoes until very soft, then peel and mash them until smooth. From there it’s all one bowl:

Fun Ways to Change Them Up

  • Nut butter swirl: drop spoonfuls of almond butter on top and swirl with a toothpick before baking.
  • Sea salt finish: a sprinkle of flaky salt before baking makes the chocolate pop.
  • Extra chocolate: fold in more chips or pile them on top. You can never have too much chocolate, right?
  • Peppermint: add a couple drops of peppermint extract and top with crushed candy canes. For the full holiday version, try my peppermint sweet potato brownies.

What to Serve With Sweet Potato Brownies

Serve them warm with a scoop of ice cream, or with a glass of homemade nut milk. For a fall dessert table, put them next to my apple butter cookies and sweet potato cheesecake. They’re also a great gluten-free dessert to bring to Thanksgiving.

FAQ

Can I use canned sweet potato? Yes. Canned sweet potato purée works. Use 1 1/2 cups.

Are these brownies gluten free? Yes. There’s no flour in them at all.

Why are my brownies so soft? Sweet potato brownies are softer than regular brownies. For firmer squares, bake a few minutes longer and let them cool completely before cutting.
