Ingredients
- Flax Egg:
- 4 tablespoons ground flax
- ½ cup water
- Dry Ingredients:
- 1¼ cups all-purpose flour
- ¼ cup cocoa powder
- 1¼ teaspoons baking soda
- ¾ teaspoon fine salt
- Zest from 1 orange
- 3 oz dark chocolate bar, roughly chopped
- Wet Ingredients:
- 2 cups mashed sweet potato (about 3–4 medium potatoes, roasted and peeled)
- 1 cup packed brown sugar
- ½ cup olive oil
- 1 tablespoon vanilla extract
Instructions
- Roast Sweet Potatoes (Ahead of Time): Preheat oven to 400°F. Pierce 3–4 medium sweet potatoes and bake for 45 minutes until fork tender. Let cool, peel, and mash. Measure out 2 cups.
- Preheat oven to 350°F and line an 8×4-inch loaf pan with parchment paper, leaving an overhang on both sides. Lightly oil any exposed parts of the pan.
- In a small bowl, mix ground flax and water to make the flax egg. Let sit until thickened.
- In a medium bowl, whisk together flour, cocoa powder, baking soda, salt, and orange zest. Set chopped chocolate aside for later.
- In a large bowl, whisk brown sugar and olive oil until smooth. Stir in vanilla and mashed sweet potato until well combined.
- Pour wet ingredients into the dry ingredients and fold gently with a spatula until just combined. Fold in chopped chocolate.
- Transfer batter into the prepared loaf pan and place it on a rimmed baking sheet.
- Bake at 350°F for 1 hour and 10 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
- Let cool in the pan for at least 30 minutes before lifting out using the parchment handles. Cool completely before slicing.
Notes
- Store leftovers wrapped in parchment at room temperature for up to 3 days.
- Freeze individual slices wrapped in parchment and stored in airtight containers or freezer bags.
- Reheat frozen slices in a toaster oven or let thaw at room temperature.
