For the Brownies

Sweet Potato Purée – Provides natural sweetness and moisture. Use mashed ripe bananas or pumpkin puree as a substitute if necessary.
Maple Syrup – Sweetens the brownies naturally while adding flavor. Honey can be used as an alternative for non-vegan options.
Almond Butter/Peanut Butter – Acts as a binding agent and adds richness. Substitute with any nut or seed butter of choice.
Pure Vanilla Extract – Enhances the overall flavor. Homemade vanilla or vanilla essence may be used as substitutes.
Avocado Oil – Keeps brownies moist. Can be replaced with melted vegan butter or coconut oil.
Cocoa Powder – Provides the chocolate flavor. Higher quality cacao will enhance the taste; cacao powder can also be used for a more intense flavor.
Sea Salt – Balances sweetness and elevates flavor. Kosher salt or table salt can be used instead.
Baking Powder – Helps brownies rise. Ensure it’s fresh for best results.
Oat Flour – Adds structure and is gluten-free. Almond or coconut flour can be substituted, but note the texture may vary.
Chopped Raw Pecans – Adds crunch and flavor. Substitute with walnuts or omit for nut-free options.

How to Make Fudgy Sweet Potato Brownies

Prepare Sweet Potato Purée: Preheat your oven to 375°F (190°C) and bake a halved sweet potato for about 25-30 minutes until tender. Once done, steam briefly, peel, and mash it into a smooth purée.
Prepare Oven & Pan: Lower the oven temperature to 350°F (176°C) and line an 8×8-inch baking pan with parchment paper, ensuring it hangs over the edges for easy removal later.
Mix Wet Ingredients: In a large mixing bowl, combine the sweet potato purée, maple syrup, almond butter, pure vanilla extract, and avocado oil. Mix well until smooth and creamy.
Combine Dry Ingredients: Add cocoa powder, sea salt, and baking powder into the wet mixture, stirring until fully integrated and there are no lumps remaining.
Add Flour: Gradually incorporate oat flour into the batter, mixing until a thick and cohesive mixture forms.
Transfer to Pan: Pour the brownie batter into the prepared pan, using a spatula to spread it evenly to the edges.
Top & Bake: If desired, sprinkle chopped pecans and dairy-free chocolate chips over the top. Bake in the preheated oven for 28-32 minutes, or until the edges look set.
Cool & Serve: Let the brownies cool in the pan for 30 minutes to 1 hour. Once cooled, slice them into squares and enjoy warm or at room temperature.

Optional: Drizzle with vegan caramel sauce for an extra special touch.
