Ingredients You’ll Need
Each ingredient in this Sweet Potato Chocolate Cake Recipe plays an important role — from the creamy sweet potatoes to the rich cocoa powder. I’ve included tips to help you pick the best versions and make substitutions if needed.
- Sweet potatoes: I always go for medium-sized, waxy varieties for a smoother puree that sweetens the cake naturally.
- Plant-based milk: I recommend unsweetened almond or oat milk for a neutral flavor, but any dairy-free milk works well.
- Maple syrup: This is my natural sweetener of choice; it adds depth without overwhelming sweetness.
- Oat flour: Finely ground oats create a tender crumb but feel free to use gluten-free oats if needed.
- Unsweetened cocoa powder: Using good quality cocoa really boosts the chocolate flavor with no extra sugar.
- Cinnamon: Just a touch enhances the warmth and richness of the cake.
- Baking soda: Helps the cake rise nicely without overpowering the texture.
- Salt: Balances the sweetness—don’t skip it!
- Vegan chocolate chips (optional): My secret indulgence for melty chocolate pockets throughout the cake.
- Chia seeds (optional): I love blending these in for extra nutrition and subtle texture contrast.
- Crushed almonds (optional): Adds a crunchy surprise that pairs beautifully with the soft cake.
Variations
I like to switch things up depending on the occasion or mood, and this Sweet Potato Chocolate Cake Recipe is super forgiving when it comes to creativity. Feel free to experiment with add-ins and flavors to make it your own.
- Nuts & Seeds Mix: One time, I swapped almonds for chopped walnuts and added pumpkin seeds—my family loved the extra crunch and earthiness.
- Spices: Try swapping cinnamon for pumpkin pie spice or a pinch of cayenne for a subtle kick and warm fall vibes.
- Fudgy Version: I often underbake it by a few minutes if I want a gooey, fudgier texture that practically melts in your mouth.
- Sweetener Swap: If you don’t have maple syrup on hand, I’ve used agave or coconut nectar with good results.
- Grain-Free: For a grain-free version, try substituting oat flour with almond flour, but note it changes the texture a bit.
How to Make Sweet Potato Chocolate Cake Recipe
Step 1: Prep the Sweet Potatoes
Start by peeling and dicing your sweet potatoes into even pieces so they cook uniformly. Boil them in a saucepan of water for about 15 to 20 minutes until fork-tender—this is key for that ultra-smooth texture. Once they’re soft, drain and let them cool slightly before pureeing in a blender or food processor until velvety smooth. I learned early on that rushing this step results in lumps that show up in the cake, so take your time here.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine your sweet potato puree with the plant-based milk and maple syrup. Whisk or stir thoroughly until everything is evenly incorporated. This ensures your cake stays moist and sweet without needing extra oils or fats.
Step 3: Add the Dry Ingredients and Optional Add-Ins
Next, sift in the oat flour, unsweetened cocoa powder, cinnamon, baking soda, and salt. If you’re tossing in vegan chocolate chips, chia seeds, or crushed almonds, fold those in gently now. Stir everything just until combined—overmixing can make the cake dense, and we want tender!
Step 4: Bake and Cool
Pour the batter into a greased bread loaf pan and smooth out the top. Bake at 400°F for 35 to 40 minutes or until a fork inserted in the center comes out mostly clean and the top is a little firm. If you love a fudgier loaf, check it a bit earlier and pull it out slightly underbaked. Once baked, let it cool completely on a wire rack before slicing—that cooling step is what really helps the cake set beautifully.
Pro Tips for Making Sweet Potato Chocolate Cake Recipe
- Don’t Skip Cooling: I’ve made the mistake of slicing it warm and got crumbly results—cool it completely for clean slices.
- Check Sweet Potato Doneness: If the potatoes aren’t soft enough, the puree won’t be smooth, affecting cake texture.
- Customize Sweetness Level: Taste your batter before baking and adjust maple syrup if you prefer it sweeter or more subtle.
- Use Fresh Ingredients: Freshly ground oat flour and quality cocoa powder really elevate the flavor and structure.
How to Serve Sweet Potato Chocolate Cake Recipe
Garnishes
I love topping this cake with a generous smear of almond or peanut butter—the creaminess complements the chocolate perfectly. Sometimes I sprinkle a pinch of flaky sea salt or toasted coconut flakes on top for an added texture and flavor boost that makes every bite interesting.
Side Dishes
Pairing this cake with a cup of strong coffee or spiced chai is my go-to for breakfast or afternoon snack time. If it’s dessert, a scoop of dairy-free vanilla ice cream or coconut whipped cream takes it to next-level indulgence without overpowering the natural flavors.
Creative Ways to Present
For birthdays or special gatherings, I’ve layered slices with vegan cream cheese frosting and fresh berries to make a beautiful layered cake. Another fun idea is to cut it into small squares and serve on a dessert platter with assorted nuts and fruit for easy sharing.
Make Ahead and Storage
Storing Leftovers
I always store leftover Sweet Potato Chocolate Cake in an airtight container in the refrigerator because of the natural moisture in the sweet potatoes. This keeps it fresh and moist for up to 5 days—much longer than room temperature storage would.
Freezing
This cake freezes beautifully—just wrap it tightly in plastic wrap and then foil, or place it in a freezer-safe container. When I thaw it overnight in the fridge, it keeps its lovely texture and flavor, making it perfect to prep ahead for busy weeks.
Reheating
I reheat slices gently in the microwave for 15–20 seconds if I want that fresh-baked warmth, or pop them in a toaster oven to get a slightly crispy edge. Just avoid overheating to keep the cake moist and tender!
FAQs
-
Can I use canned sweet potatoes for this recipe?
You can substitute canned sweet potatoes in a pinch, but fresh boiled sweet potatoes typically produce a sweeter, smoother puree and better cake texture. If using canned, drain well and mash thoroughly to remove excess moisture.
-
Is this Sweet Potato Chocolate Cake Recipe gluten-free?
It’s naturally gluten-free if you use certified gluten-free oat flour. Regular oats can sometimes be cross-contaminated with gluten, so check your packaging if you have sensitivities.
-
How do I make the cake more fudgy?
Simply reduce bake time slightly by 5 minutes and remove the cake when a fork comes out with a few moist crumbs. This creates a decadent, fudgier texture.
-
Can I use other flours instead of oat flour?
Yes, almond flour or buckwheat flour work well, but you’ll notice a change in texture and density. It’s best to experiment and adjust moisture if needed.
-
Do I need to peel the sweet potatoes?
Peeling is recommended for a smoother puree and finer cake texture, but if you don’t mind a bit of texture and extra fiber, you could leave the skin on—just be sure to blend really well.

Instructions
- Preheat Oven and Cook Sweet Potatoes: Preheat your oven to 400°F (200°C). Meanwhile, bring a saucepan of water to boil and add the diced sweet potatoes. Boil them for 15 to 20 minutes or until fork-tender.
- Puree Sweet Potatoes: Drain the sweet potatoes and let them cool slightly. Remove any remaining skin, then puree the sweet potatoes in a blender or food processor until smooth and creamy.

- Prepare for Baking: Grease a bread loaf pan to prevent sticking. Transfer the dough into the pan, spreading it out evenly.
