Fudgy Sweet Potato Brownies Recipe — Chewy, Moist & Guilt-Free

Want the fudgy goodness of brownies with a boost of vegetable nutrition? These Sweet Potato Brownies are rich and indulgent yet a healthier twist on boxed brownies.

I’ve been experimenting with brownie recipes and I love adding a seasonal or unexpected ingredient. These sweet potato brownies combine creamy mashed sweet potato with chocolate for a fudgy, satisfying result. They’re simple to make and freeze well, so they’re great to keep on hand.

Why Make These Sweet Potato Brownies?

• Nutritious – Sweet potatoes add natural sweetness and provide vitamins like A and C, so you can enjoy brownie flavor while boosting nutrition.
• Fudgy texture – The mashed sweet potato gives these brownies a dense, fudgy mouthfeel that’s irresistible.
• Freezer-friendly – These brownies freeze well; they taste great straight from the freezer or after thawing.

Ingredients Needed

• Dark chocolate chips – or chocolate chunks; semi-sweet or milk chocolate also work.
• Butter – a small amount; swap with coconut oil for a dairy-free version. Use additional fat to grease the pan.
• All-purpose flour – other flours like whole wheat or oat flour may work but will change texture; avoid coconut flour without adjusting other ingredients.
• Unsweetened cocoa powder – dutch-processed cocoa or raw cacao powder are fine alternatives.
• Baking soda – helps the brownies rise slightly.
• Salt – enhances the chocolate flavor; omit if limiting sodium.
• Coconut sugar – or brown sugar; coconut sugar offers a lower-glycemic option.
• Mashed sweet potato – use homemade puree or canned sweet potato puree.
• Eggs – two large eggs; flax eggs can be used for a denser vegan version if combined with coconut oil.
• Vanilla extract – pure vanilla enhances the chocolate flavor.

How to Make Your Own Sweet Potato Puree

You can buy canned sweet potato puree, but making it at home is easy. Roast, steam, or pressure-cook your sweet potatoes. Roasting is my preferred method because it’s hands-off and brings out great flavor.

To roast: Preheat the oven to 425°F. Wrap whole sweet potatoes in foil and place on the oven rack. Roast 45–60 minutes, depending on size, until tender. Let cool enough to handle, cut open, and scoop the flesh into a bowl. Mash with a fork or potato masher until smooth and use as directed.

How to Make Sweet Potato Brownies

STEP 1: MELT CHOCOLATE + BUTTER

Combine the chocolate chips and butter in a small pot over low heat, stirring until melted and smooth. Take care not to burn the chocolate. Alternatively, melt in the microwave in 30-second increments. Remove from heat and let cool slightly.

STEP 2: COMBINE DRY INGREDIENTS

In a large bowl whisk together the flour, cocoa powder, baking soda, salt, and coconut sugar until evenly mixed.

STEP 3: ADD WET INGREDIENTS

Stir the mashed sweet potato, eggs, and vanilla into the melted chocolate and butter until combined. Gradually add the dry ingredients to the wet mixture and fold until just incorporated.

STEP 4: BAKE

Pour the batter into a greased 8 x 8-inch baking pan. Bake at 350°F for 25–30 minutes—25 minutes yields a fudgier result—until the top is set and the edges are slightly crisp. Cool in the pan for 20 minutes before slicing. I like to cut into 9 squares (3 x 3). Let them reach room temperature before storing.

Storage Instructions

Refrigerator: Store in an airtight container for up to 5 days.

Freezer: Freeze in an airtight container for up to 3 months. Place parchment between layers to prevent sticking. Thaw in the fridge or at room temperature.
