Cook the sweet potato according to your preferred method. I chop mine into large chunks and boil it in water for 15 to 20 minutes, or until the chunks of potato are very tender. Allow the potato to cool (I transfer it to a sealable container and refrigerate it). Once cool, remove and discard the peel. Note: you can cook the potato and refrigerate it up to 5 days in advance.

Preheat the oven to 350 degrees F and line a 9-inch square baking pan with parchment paper.

Mash the sweet potato into a bowl or measuring cup and measure out 1 cup of mashed potato.

Add the mashed sweet potato to a large mixing bowl along with the almond butter, eggs, pure maple syrup and vanilla extract and stir well until everything is well-combined (wet ingredients).

Stir in the cocoa powder, baking soda, sea salt, and ground cinnamon until a thick creamy batter forms (no need for a separate bowl here).

Add in the chocolate chips and stir until they are well-incorporated into the batter.

Pour the brownie batter into the prepared baking pan and spread it into an even layer. If desired, sprinkle with extra chocolate chips.

Bake on the center rack of the preheated oven for 23 to 28 minutes, or until the brownies reach desired level of doneness. For fudgy, gooey brownies, bake for 23 minutes.

Allow the brownies to cool completely (at least one hour) before slicing and serving. You can slice the brownies before they have finished cooling if you’d like, but the slices won’t hold together quite as well. If you’re fine with that, proceed!

Serve with a scoop of ice cream for an even more decadent dessert.
