Ingredients

  • cups mashed sweet potato about 2 medium
  • 3 large eggs
  • 1/2 cup honey
  • 1/2 cup peanut butter
  • 6 Tablespoon cocoa powder
  • ¾ cup oat flour
  • teaspoon vanilla extract
  • 3/4 teaspoon baking soda
  • 1/3 teaspoon salt
  • 1/2 –2/3 cup chocolate chips or chopped dark chocolate

Instructions

  • Preheat oven to 350°F. Line a 9×13 inch baking pan with parchment paper or grease well. Then, in a large mixing bowl, whisk together mashed sweet potato, eggs, honey, peanut butter, and vanilla until smooth.
    1¾ cups mashed sweet potato, 3 large eggs, 1/2 cup honey, 1/2 cup peanut butter, 1½ teaspoon vanilla extract
  • In a separate bowl, mix the cocoa powder, oat flour, baking soda, and salt. Stir into the sweet potato mixture.
    6 Tablespoon cocoa powder, ¾ cup oat flour, 3/4 teaspoon baking soda, 1/3 teaspoon salt
  • Fold in chocolate chips and mix until everything is combined. It's normal for the batter to be a little lumpy.
    1/2 –2/3 cup chocolate chips or chopped dark chocolate
  • Spread the batter evenly in the prepared baking pan. Bake for 25-30 minutes, or until the center is just set and a toothpick comes out with moist crumbs.
  • Let cool in the pan for at least 30 minutes before slicing.
  • Finally, drizzle the tops with peanut butter. If your peanut butter needs to be thinner for drizzling, it can be microwaved for 10 seconds, stirred, then microwaved a little more until you get the consistency you need. Enjoy!

Notes

  • Refrigerator: Store the sweet potato brownies in an airtight container in the refrigerator for up to five days. Their moist texture holds up especially well when chilled.
  • Freezer: Wrap individual brownies in plastic wrap and place them in a freezer safe container for up to three months. Thaw them overnight in the refrigerator or for about an hour at room temperature.
  • Bake the sweet potatoes with the peel on: Baking concentrates their natural sweetness and prevents the mashed sweet potato from becoming watery. Scoop out the soft centers once they are cool enough to handle.
  • Mash out any stringy pieces: A potato masher works well, but a food processor can create an especially smooth puree for the brownie batter.
  • Break up cocoa powder lumps first: I like topress any lumps with the back of a spoon or sift the cocoa powder before adding it to the mixing bowl.
  • Let the brownies cool before judging the texture: They will be very soft when they first come out of the oven and will continue setting as they cool.
