Love baking with sweet potatoes? Try my sweet potato brownies, sweet potato blondies, sweet potato muffins, and vegan sweet potato pie next. If you’re not baking with sweet potatoes, you’re missing out. Don’t get me wrong—I know it sounds weird, but once you take a bite of this moist, crumbly chocolate cake, you’ll wonder why you didn’t think of it sooner!
Why I love this recipe
NO sweet potato flavor. I promise you won’t be able to taste it whatsoever. The perfect texture. Sweet potato adds moisture and keeps the cake soft while keeping the fat content low. All you need is a food processor. The cake batter is made entirely in your food processor, so clean-up is done in a snap. Naturally diet-friendly. This recipe has no gluten or dairy because you don’t need it!
Ingredients needed
Coconut flour. My preferred alternative to all-purpose flour. It’s high fiber and high absorbency, helping to give the cake a perfect crumb. Sift it first to remove any clumps. Cocoa powder. Use either dark cocoa powder or a good quality Dutch-processed cocoa powder. Granulated sugar. I used white sugar, but brown sugar or coconut sugar can also be used. Baking powder. Gives some rise and fluffiness to the cake. Salt. Brings out the natural sweetness. Sweet potato. Cooked, cooled, and mashed. See my tips below for the best way to puree your sweet potato! Eggs. Room temperature eggs are best. While I haven’t tested this recipe without eggs, you’re welcome to swap them for an egg substitute. I’ve successfully made this using an egg replacer (Bob’s Ener-G is my favorite). Coconut oil. Gives the cake a moist texture without butter. Alternatively, vegetable oil can also be used. Maple syrup. For sweetness and extra moisture. Agave nectar also works. Vanilla extract. A must for any good cake recipe! Chocolate frosting. Use your favorite frosting. I’ve used both my healthy frosting and dairy free frosting.
How to make sweet potato cake
I’ve included step-by-step photos below to make this recipe easy to follow at home. For the full printable recipe instructions and ingredient quantities, scroll to the recipe card at the bottom of this post. “Arman!! I MADE THIS!!!! Wowee! What a show-stopper!” – Kelley You have a few options when it comes to making mashed sweet potatoes. Here’s what I suggest:
Microwave. Follow my microwave sweet potato recipe, or cut the potatoes into chunks, place them in a microwave-safe bowl, and pour 2-3 inches of water on top. Microwave for 6-7 minutes or until fork-tender. Air fryer. Follow my air fryer baked sweet potato recipe, or place the washed potatoes in a greased air fryer basket and air fry at 200C/400F for 20 minutes. Oven. Cover the potatoes in aluminum foil and bake for 40-50 minutes, until soft. Stovetop. Fill a pot with water over medium heat. Bring to a boil, add the potatoes, and reduce the heat to low. Let them simmer for 30-35 minutes or until tender.
Once the potatoes are cooked and cooled, puree them separately or add them to the food processor with the remaining ingredients. Step 1- Prep. Preheat the oven to 180C/350F and grease a 9 or 10-inch cake pan.
Arman’s recipe tips
Save time. When I’m short on time, I’ll use canned puree. Just make sure it’s 100% unsweetened. Don’t overbake the cake. Once a toothpick comes out with a few moist crumbs, it’s safe to remove from the oven. Even if the cake seems fragile, it’ll continue to cook as it cools. Make a double-layered cake. Double up the cake and frosting ingredients. Wait for the cake layers to cool completely before frosting and layering.
Storage instructions
To store: Store the leftover cake in an airtight container in the refrigerator for up to two weeks.
Add spices. Whisk in cinnamon, nutmeg, or instant coffee for more flavor. Make a cream cheese frosting. In a large bowl, beat together softened cream cheese, vanilla, and powdered sugar until smooth. Play around with mix-ins. Try chopped pecans, walnuts, fresh raspberries, or toasted coconut flakes.
To freeze: Place cake slices in a freezer-safe container and freeze for up to six months. Let them thaw overnight in the fridge.
