Ingredients for sweet potato brownie recipe no peanut butter
Twelve simple ingredients transform into decadent, fudgy brownies with warm cinnamon notes—no peanut butter needed!
| Ingredient | Amount | Notes |
|---|---|---|
| Medium Sweet Potatoes 🍠 | 2 large | Peeled, cubed into 1-inch pieces |
| Unsweetened Dark Chocolate 🍫 | 8 oz | 70% cocoa or higher, chopped |
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for best texture |
| Granulated Sugar 🍚 | 1 cup | Light brown preferred |
| Ground Cinnamon 🌿 | 1 ½ tbsp | High-quality for warmth |
| Baking Powder 🧂 | ½ tsp | Aluminum-free preferred |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Pure Vanilla Extract 🌸 | 1 tsp | High-quality for flavor |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For moisture and richness |
| Semisweet Chocolate Chips 🍫 | 1 cup | Optional for texture |
| Chopped Walnuts 🥜 | ½ cup | Optional for crunch |
The sweet potatoes are the star here—organic medium sweet potatoes from the produce section work best, with their natural sweetness caramelizing beautifully. Trader Joe's and Whole Foods often have the freshest, but any grocery store will do. Look for ones that are firm and vibrant orange—avoid any with soft spots. Roasting them first intensifies their sweetness, so don't skip this step. For extra richness, I sometimes add a pinch of nutmeg alongside the cinnamon, but it's optional. The key is to cube them evenly—about 1-inch pieces so they cook through without burning.
No dark chocolate on hand? High-quality semisweet chocolate bars (like Ghirardelli or Lindt) work in a pinch, but they won't have the same depth. The flour is non-negotiable—King Arthur or Bob's Red Mill brands sift beautifully and give the best texture. Want to skip the chocolate chips? Crushed pretzels or white chocolate chunks add a fun twist. The walnuts are optional, but if you use them, toast them first for maximum flavor. For a deeper cinnamon taste, toast the spice in a dry pan for 30 seconds before adding it to the batter—it releases those aromatic oils that make all the difference.
These brownies keep beautifully—3-4 days at room temperature wrapped in foil, or 1 week in the fridge. For longer storage, slice and freeze them on a tray before transferring to a bag—up to 3 months. Reheat slices in a 350°F oven for 5-10 minutes to restore that fudgy texture. Pro tip: Double the recipe and freeze half for when cravings hit later. They pair perfectly with vanilla ice cream or a sprinkle of flaky sea salt for contrast. The sweet potato flavor actually improves overnight, so leftovers taste even better!

Step-by-step instructions for sweet potato brownies with cinnamon depth
Here's how to transform humble sweet potatoes into decadent, fudgy brownies with warm spice notes.
👨🍳 Step 1: Roast Sweet Potatoes Until Caramelized
Preheat your oven to 400°F and line a baking sheet with parchment paper. Spread the 2 large medium sweet potatoes (peeled and cut into 1-inch cubes) in a single layer, ensuring they don't overlap. Drizzle lightly with 1 tablespoon of the extra-virgin olive oil and sprinkle with ½ teaspoon of the salt.
Roast for 25-30 minutes until the edges turn golden brown and the cubes soften when pierced with a fork. You want them caramelized but not mushy—this roasting step develops their natural sweetness and creates that perfect moisture balance in your brownies. Let them cool completely before processing.
🍳 Step 2: Melt Chocolate and Mix Wet Ingredients
While the sweet potatoes roast, place the 8 oz unsweetened dark chocolate in a microwave-safe bowl and melt in 30-second bursts on high power, stirring between each interval until completely smooth. Let it cool slightly to 110°F—it should be liquid but not hot to the touch.
In a separate large bowl, combine the melted chocolate with the ½ cup extra-virgin olive oil, 1 cup granulated sugar, and 1 teaspoon pure vanilla extract. Whisk vigorously until the mixture is completely smooth and glossy. The sweet potatoes should be cool enough to handle now—add them to the bowl and mash with a potato masher or fork until you achieve a thick, chunky puree with no large lumps.
👨🍳 Step 3: Combine Dry Ingredients for Perfect Texture
In a medium bowl, whisk together the 1.5 cups all-purpose flour, 1.5 tablespoons ground cinnamon, ½ teaspoon baking powder, and remaining ½ teaspoon salt. Sift the mixture directly into the sweet potato-chocolate mixture and fold gently with a spatula until just combined. You want to maintain some air pockets for lift without overmixing.
Fold in the 1 cup semisweet chocolate chips and ½ cup chopped walnuts (if using) until evenly distributed. The batter will be thick and fudgy—this is exactly what we want! Pour the batter into a 9x9-inch baking pan lined with parchment paper, smoothing the top with a spatula. The pan should be filled about ¾ full for proper baking.
🔥 Step 4: Bake to Fudgy Perfection
Bake at 350°F for 25-30 minutes until a toothpick inserted in the center comes out with moist crumbs (not wet batter). The edges should be set but the center should still appear slightly underdone—this ensures maximum fudginess. Don't overbake; sweet potato brownies continue cooking slightly as they cool.
Here's the thing—when you open the oven, the brownies will look slightly underdone. That's intentional! Let them cool in the pan for 15 minutes before transferring to a wire rack. The residual heat will finish the cooking process, resulting in that signature fudgy texture with crackly tops. Once completely cool, cut into 12 squares for perfect serving portions.
⏰ Step 5: Rest and Enjoy the Warm Cinnamon Notes
For best results, let the brownies rest at room temperature for at least 1 hour before serving. This allows the flavors to fully meld and the texture to set properly. Each bite should deliver rich chocolate depth, warm cinnamon undertones from the sweet potatoes, and a satisfying fudgy yet slightly crispy texture.
Store any leftovers in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months. These brownies improve with age as the flavors deepen—perfect for making ahead for gatherings! The walnuts add delightful crunch, while the chocolate chips melt into gooey pockets throughout.
Pro Tips For Making Sweet Potato Brownie Recipe No Peanut Butter
- ROAST SWEET POTATOES FIRST: I learned this the hard way—raw sweet potato purée tastes like glue in brownies. Roast them at 400°F (200°C) for 45 minutes until fork-tender, then mash with a fork (no blender) to keep the texture smooth but not gummy. The starch breaks down better this way, and the flavor deepens.
- MELT CHOCOLATE LOW AND SLOW: After burning three batches, I finally figured out: dark chocolate seizes when it hits steam from hot liquids. Temper it gently—drop chopped chocolate into a bowl over barely simmering water (not boiling), stirring until it’s 60% melted but still thick. This keeps it glossy and prevents that grainy texture.
- WEIGH YOUR FLOUR: I skip this when I’m lazy, but the dish is noticeably better when I don’t. Spooning flour into cups leaves too much air, making brownies cakey. Use a kitchen scale for 120g (about 1 cup) and sift it directly into the dry ingredients. The result? A fudgier, denser brownie that holds its shape.
- BAKE UNTIL EDGES CRACK: Watch the heat—these brownies are trickier than they look. Pull them when the edges pull away from the pan but the center still jiggles slightly (about 25–30 minutes at 350°F/175°C). Overbaking dries out the sweet potato moisture, turning them into dense bricks. Let them cool 10 minutes before slicing—yes, even if you’re impatient like me.
Essential equipment for this recipe
Baking Pan Essentials
A 9x9-inch metal baking pan is your best friend for even heat distribution and crisp edges. I recommend a Wilton Professional Non-Stick Baking Pan—it prevents sticking and makes cleanup effortless. Line it with parchment paper for foolproof release, especially since sweet potato brownies can be dense.
If you don’t have a 9x9-inch pan, a 9x13-inch works, but reduce baking time by 5-7 minutes and cut into 16 squares instead. 🔥
Mixing Tools Matter
Use a heatproof spatula (like OXO Good Grips) for folding dry ingredients into the batter—it’s sturdy enough to handle melted chocolate without bending.
A hand mixer (or whisk) is perfect for blending the wet ingredients smoothly, while a potato masher ensures the roasted sweet potatoes stay slightly chunky for texture. Avoid plastic tools near melted chocolate—they can warp. ✨
Precision Measuring
Invest in a digital kitchen scale (like Escali Primo) for accurate measurements, especially for flour and sugar. Spooning flour into cups compresses it, leading to dry brownies. For cinnamon, use a spice scoop (like Penzeys) to avoid clumps.
A fine-mesh sieve helps sift dry ingredients evenly, preventing lumps in the batter. Precision here makes all the difference in texture.
Chocolate Melting Gear
Melt chocolate in 30-second bursts using a microwave-safe bowl—Pyrex or CorningWare handles heat best. For stovetop melting, a double boiler (or heatproof bowl over simmering water) prevents scorching.
A thermometer (like Thermoworks) ensures chocolate reaches 110°F—too hot, and it seizes; too cool, and it won’t blend smoothly. 💫
Cooling and Cutting
A wire cooling rack (like OXO Good Grips) prevents soggy bottoms while cooling. For cutting, a sharp 8-inch chef’s knife (or brownie cutter) ensures clean squares. Let brownies rest 15 minutes in the pan before transferring—they’ll firm up as they cool, making slicing easier.
A parchment-lined tray catches crumbs during cutting for zero mess. 💪

Frequently asked questions
Why does this recipe use roasted sweet potatoes instead of mashed?
Roasting caramelizes the sweet potatoes, intensifying their natural sweetness and adding depth of flavor that mashed sweet potatoes can't match. The roasting also creates a slight texture contrast in the brownies—tiny pockets of tender sweet potato throughout—while keeping them moist. Plus, roasting removes excess liquid that could make the batter too wet.
Can I make these brownies gluten-free?
Yes! Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill) and add ½ teaspoon xanthan gum to improve texture. The sweet potato's moisture helps compensate for any slight dryness from gluten-free flours. For best results, use a scale to measure flour precisely—cups can vary dramatically in density.
What if my brownies turn out too cakey instead of fudgy?
Overbaking is the most common cause—these brownies should look slightly underdone in the center when done. If they're cakey, try reducing baking time by 2-3 minutes next time or check your oven with an oven thermometer (many run hotter than set). For extra fudginess, increase the chocolate to 10 oz and reduce flour to 1.25 cups.
Can I substitute the olive oil with butter?
You can use ½ cup melted butter (instead of olive oil) for a richer flavor, but the texture will be slightly less dense. The olive oil keeps the brownies more moist and fudgy. If using butter, let it cool to 100°F before mixing to prevent melting the chocolate. For a hybrid version, use ¼ cup olive oil + ¼ cup melted butter for best of both worlds.
How do I store these brownies to keep them fresh?
Wrap tightly in plastic wrap or store in an airtight container at room temperature for 3-4 days. For longer storage, slice and freeze on a tray before transferring to a bag—up to 3 months. To revive frozen brownies, thaw at room temperature for 1 hour** before serving. They actually taste better the next day as flavors meld!
