I found this recipe on https://chocolatecoveredkatie.com/sweet-potato-brownies-recipe/
3/4 cup sweet potato puree
1 cup peanut or almond butter OR allergy-friendly sub
1 tsp pure vanilla extract
1/4 cup + 2 tbsp flour (Oat, white, or spelt flour all work, and readers have reported success with almond flour)
1/2 cup mini chocolate chips + more for the top optional
2/3 cup sugar
1/4 cup + 2 tbsp cocoa powder
1 1/2 tsp baking soda
1/8 tsp salt
Preheat oven to 325 F. Line an 8-inch pan with parchment paper or grease well. Gently heat your nut butter until easily stir-able. Then whisk it together with the sweet potato and vanilla extract in a large bowl. In a separate bowl, stir together all remaining ingredients – make sure that baking soda is evenly incorporated! Pour dry into wet (not the other way around), and smooth into the prepared pan, scooping out all traces of batter and using a second sheet of parchment to really smooth it down evenly. Bake on the center oven rack 20 minutes. It will look a little underdone, but it firms up as it cools. (If, for some reason, yours is still too gooey after cooling, loosely cover and let it sit in the fridge a few hours.)
