Sweet Potato Brownies


Made with melted chocolate chips, eggs, and sugar for the base, it's almost hard to believe there's an entire sweet potato lurking in these extra gooey brownies. For some of us (more than others), getting our little ones to eat nutritious fruits and vegetables can be a herculean task, so we have to get downright creative. When a sweet potato is roasted and allowed to cool slowly, an enzyme in the potato transforms the starches in the flesh into complex sugars, making the sweet potato softer and sweeter. It's these natural syrupy sugars in the flesh of the sweet potato that compliment the brown sugar and enhance the chocolaty-ness of the brownies—not to mention the added moisture (read: gooeyness) that the sweet potato lends to the chocolate squares. If anything, these brownies will make you believe in having a dessert that's exceptionally tasty while also laced with fiber, antioxidants, vitamins, and minerals. Dense, rich, and a little more nutrient conscious than your average brownie, you might not want to go back to regular brownies ever again.

  • 1/2 cup unsalted butter

  • 2 cups bittersweet chocolate chips

  • 1 cup mashed sweet potato*

  • 1/2 cup brown sugar

  • 1 cup granulated sugar

  • 4 eggs

  • 2 1/2 teaspoons vanilla

  • 1/2 teaspoon kosher salt

  • 2/3 cup all-purpose flour

  • 1/2 cup unsweetened cocoa powder

  • Powdered sugar for dusting, optional


  1. Preheat oven to 325°F. Grease and line a metal 9-by-13-inch baking dish with parchment paper; set aside. In a medium saucepan, melt butter until boiling. Immediately add chocolate chips and remove from heat. Stir once to coat chocolate chips in butter, and allow to sit for 5 minutes.

  2. In a large mixing bowl, whisk together sweet potato, brown sugar, granulated sugar, eggs, vanilla, and salt. Whisk chocolate and butter mixture until chocolate is fully melted and combined with butter. Add chocolate mixture to sweet potato mixture and whisk to incorporate.

  3. Sift flour and cocoa into the bowl with the liquid ingredients, and stir until no pockets of dry ingredients remain. Pour into prepared baking dish, level batter with spatula, and bake until a toothpick inserted comes out clean and edges have set, about 35 minutes. Allow to cool completely before slicing and dusting with powdered sugar, if desired.

Chef's Notes

To make the mashed sweet potato, wrap sweet potatoes in aluminum foil and roast in a 425°F oven for 1 1/2 hours. Turn off the oven and allow the sweet potatoes to cool in the oven for 2 hours. This allows more of the starches in the sweet potato to transform into complex sugars, making the sweet potato flesh both sweeter and softer. Peel and mash the sweet potatoes.
