How to Make Vegan Sweet Potato Brownies
Step 1: Prepare the Sweet Potatoes
Peel and cube the sweet potatoes, then steam or boil them until tender — about 10–15 minutes. Drain well, mash until smooth, and let them cool slightly before using.
Pro Tip: Roasting sweet potatoes gives a caramelized flavor that enhances the sweetness of your brownies.
Step 2: Make the Flax Eggs
In a small bowl, mix ground flaxseed with water. Stir and let sit for 5–10 minutes until thickened. This will act as your egg substitute and help bind the brownies.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, combine mashed sweet potatoes, nut butter, maple syrup, melted coconut oil (if using), vanilla extract, and flax eggs. Whisk until smooth and creamy.
Step 4: Add the Dry Ingredients
Add cocoa powder, baking powder, and sea salt. Stir gently until well combined. The mixture will be thick and glossy — perfect for fudgy brownies.
If desired, fold in dark chocolate chips or chunks for a double chocolate experience.
Step 5: Spread the Batter
Line an 8×8-inch baking pan with parchment paper and lightly grease it. Pour in the batter, smoothing the top with a spatula.
Step 6: Bake to Fudgy Perfection
Bake at 350°F (175°C) for 25–30 minutes. The edges should look set, but the center should remain slightly soft.
Don’t Overbake: These brownies continue to firm up as they cool.
Step 7: Cool and Slice
Allow brownies to cool completely in the pan — at least 1 hour. Slice into squares using a sharp knife. For perfectly clean cuts, chill them in the fridge for 20 minutes before slicing.
The Secret to Fudgy Brownies
The secret lies in moisture and balance:
-
Sweet potatoes keep the brownies soft and fudgy.
-
Nut butter adds fat for richness and smooth texture.
-
Minimal baking ensures they don’t dry out.
-
Cooling completely locks in the dense, chocolatey interior.
Optional Add-Ins and Toppings
Customize your sweet potato brownies with extra flavor or texture:
-
Crunchy Nuts: Walnuts, pecans, or almonds.
-
Sweet Swirls: Add a peanut butter or almond butter swirl before baking.
-
Spices: A pinch of cinnamon or espresso powder for depth.
-
Sea Salt Finish: Sprinkle flaky sea salt on top for a sweet-salty bite.
-
Frosting Option: Drizzle with melted dark chocolate or coconut ganache.

Expert Tips for the Best Vegan Brownies
-
Use ripe, sweet potatoes: Naturally sweeter potatoes make better brownies.
-
Measure mashed potato, not whole: Always measure after mashing to ensure correct proportions.
-
Mix gently: Overmixing can make brownies dense or dry.
-
Chill before slicing: Makes cutting clean squares much easier.
-
Store properly: Keep them moist and chewy by storing in an airtight container.
How to Store & Freeze
Room Temperature:
Store in an airtight container for up to 2 days.
Refrigerate:
Keeps fresh up to 5–6 days. The texture becomes even fudgier when chilled.
Freeze:
Place cooled brownies between parchment layers in a freezer-safe container for up to 3 months. Thaw at room temperature or warm briefly in the microwave.
