How to Make Sweet Potato Brownies

Handsfree mode (keeps screen awake)

Mash the sweet potato

Measure the cooked sweet potato and mash it until very smooth with no firm bits.
Use a food processor or blender if you want the smoothest brownie texture.
Prep the pan and oven

Heat the oven to 350°F and line an 8-inch square pan with parchment.
Lightly grease any exposed pan sides so the brownies release cleanly.

Mix the wet ingredients

Whisk the melted butter, granulated sugar, and brown sugar until glossy and well combined.
Whisk in the eggs, vanilla, and mashed sweet potato until the mixture looks smooth.
Add the dry ingredients

Add the cocoa powder, flour, baking powder, and salt to the bowl.
Fold gently just until no dry streaks remain, then stir in three-quarters of the chocolate chips.
Fill the pan

Spread the batter evenly in the prepared pan and scatter the remaining chocolate chips on top.
Smooth the surface with a spatula so the brownies bake evenly.

Bake and cool

Bake for 28 to 32 minutes, until the center looks set and moist crumbs cling to a tester.
Cool completely before slicing for the cleanest squares and the fudgiest texture.

Substitutions

Butter for refined coconut oil: Use the same amount for a dairy-free option with a soft, fudgy crumb. Refined coconut oil keeps the chocolate flavor front and center.
All-purpose flour for 1-to-1 gluten-free flour: A good cup-for-cup blend keeps the brownies tender and easy to slice. The texture stays dense and satisfying.
Semisweet chocolate chips for dark chocolate chunks: Dark chocolate makes each bite bolder and a little less sweet. Chopped chunks also create larger melted pockets.

Tips

Puree for a smoother batter: Silky sweet potato blends into the batter more evenly than a rough mash. That gives the brownies a tighter, fudgier crumb.
Measure flour carefully: Spoon the flour into the measuring cup, then level it off. Packed flour can make the brownies dry.
Check early for doneness: Start testing at 28 minutes, especially with dark metal pans. A few moist crumbs mean the center will finish as it cools.
Cool before cutting: Warm brownies seem fragile and can stick to the knife. Fully cooled brownies slice into cleaner, neater squares.

FAQ

Can I use canned sweet potato puree?: Yes, if it is plain and not pie filling. Drain any extra moisture so the batter stays thick.
Why did my brownies turn out cakey?: Too much flour or extra mixing can cause a lighter crumb. Measure carefully and fold only until combined.
How do I know when they are done?: The top should look set, and the edges should pull away slightly. A tester should come out with moist crumbs, not wet batter.
Can I make these ahead?: Yes, and the flavor often deepens by the next day. Store them airtight at room temperature for two days or refrigerate longer.

Serving Suggestions

A small sprinkle of flaky salt makes the chocolate taste deeper and balances the sweet potato's natural sweetness.

Serve these brownies with cold milk, hot coffee, or a scoop of vanilla ice cream for dessert.

For a holiday version, add chopped pecans and a pinch of cinnamon to the batter.
