Equipment

  • Sheet pan
  • Parchment paper
  • Aluminum foil
  • Mixing bowls
  • Measuring cups and spoons
  • Silicone spatula
  • Square 8x8 dish

Ingredients
  

  • 1 cup mashed sweet potato about 2 medium sweet potatoes
  • 1/2 cup tahini
  • 6 tbsp butter melted
  • 2 large eggs
  • 1/3 cup maple syrup
  • 1 tsp vanilla
  • 1/3 cup raw cacao powder
  • 1/2 tsp sea salt
  • 1/2 tsp baking soda
  • 1 cup chocolate chips, divided look for at least 70% cacao
  • 1 cup chopped walnuts optional

Instructions
 

  • Make the mashed sweet potatoes. Preheat your oven to 400°F. Take 2 sweet potatoes and wrap each in a layer of parchment paper and then aluminum foil.
  • Place them on a sheet pan and roast for an hour. They should be soft and smushy. Remove from the oven and open their foil and parchment packages to cool.
  • Once cool, peel away the skin and mash the flesh. Store it in an airtight container until you’re ready to make the brownies. When you're ready to bake, measure out 1 cup of mashed sweet potato.
  • Preheat the oven to 350°F. Line an 8x8 square dish with parchment paper.
  • In a large mixing bowl, mix together the mashed sweet potato, tahini, melted butter, eggs, maple syrup, and vanilla extract until smooth.
  • In a separate medium bowl, whisk the cacao powder, salt, and baking soda until combined.
  • Add the dry ingredients to the sweet potato mixture. Stir until just combined.
  • Fold in the dark chocolate chips and walnuts, if using.
  • Pour into the prepared pan. Sprinkle with flaky sea salt and another handful of chocolate chips.
  • Bake for 30-40 minutes or until a toothpick inserted in the center comes out mostly clean.
  • Let the brownies cool for at least 20 minutes before slicing and serving.

Notes

Tips & variations

Prepare the sweet potato up to 3 days ahead of time. These brownies come together really fast when the sweet potato mash is already made. Pro tip: place the sweet potatoes in the oven while you’re roasting other veggies for dinner or after you already have the oven preheated.
Swap out the tahini for peanut butter, almond butter, or sunflower seed butter. Check the label to make sure it doesn’t include sugar.
Serve them warm or cold, straight from the fridge. (They’re extra fudgy when cold.) They’re delicious with a scoop of maple vanilla bean ice cream, thick Greek yogurt, or chocolate avocado frosting.

Storage

Once cooled, store leftovers in an airtight container in the fridge. To freeze, place squares on a sheet pan lined with a baking pan liner and place in the freezer. Once frozen, move brownie squares into a silicone food storage bag and keep them in the freezer.
