Sweet Potato Cake with Chocolate Coconut Frosting (Dairy-Free)

Sweet Potato Cake with Chocolate Coconut Frosting is generously spiced with cinnamon and ultra soft and tender thanks to the addition of sweet potato. It’s topped with a creamy, dairy-free coconut whip to make it the ultimate snack cake!

Hey friends! So, after a flurry of fresh salads and cozy soups in January, I have a few healthier sweet treats lined up to share during February, starting with this spiced sweet potato cake.

I’m going to be honest. I’ve probably enjoyed this cake a little too much over the last few weeks.

During Snowmageddon 2020 (which is what us Newfoundlanders are affectionately calling the winter storm that brought our city to a standstill a few weeks ago), I baked a lot! It was so nice to have the time to just bake for fun. There were brownies, there were cookies and there was cake. A lot of cake.

This dairy-free cake with sweet potatoes to be exact.

This recipe came about as a result of having leftover mashed sweet potato, a hankering for something sweet and limited ingredients for baking. (The grocery stores were closed for 4 full days!)

While I enjoyed this cake as a bedtime snack with a cup of tea (no judgement, please, we were snowed in!), it also makes a wonderful dinner party dessert or afternoon snack. The coconut whip topping is optional, but totally worth it for an extra special treat.

Why you’ll love this sweet potato cake recipe too:

• You need just 11 ingredients (and that includes the frosting).
• Besides preparing the sweet potato, the cake comes together in one bowl with a whisk.
• It’s a great way to use up any leftover cooked sweet potato.
• It’s on the healthier side with whole wheat flour and coconut sugar as the main ingredients.
• You can forgo the frosting for an even simpler snack cake.

What you’ll need to make this dairy-free cake:

• Whole wheat flour
• Coconut sugar
• Cinnamon
• Baking soda
• Salt
• Nut milk
• Mashed sweet potato
• Extra virgin olive oil
• Coconut milk
• Maple syrup
• Cocoa

How to make this vegan sweet potato cake:

• Start by preparing your sweet potato. I find the quickest way to make mashed sweet potatoes is to peel and cut them up into small pieces, and then boil the pieces in water until fork tender. Once cooked, drain, mash and set aside to cool.

• In a large bowl, whisk together your dry ingredients. Stir in the cooled sweet potato, milk and oil until well incorporated.

• Pour into a 9-inch pan lined with parchment paper and bake for 24-26 minutes on 350F. Let the cake cool.

• For the frosting, add your solidified coconut milk (more on this in the recipe card), maple syrup and cocoa to an electric mixer and beat on high until light and creamy. Spread over top of the cake. Sprinkle on some chocolate shavings if you’re feeling fancy!

Frequently Asked Questions:

• What does a sweet potato cake taste like? This cake tastes like a classic spice cake with lots of cinnamon. Sweet potatoes have a sweet taste so they work well in baked goods. This cake, however, only contains half a cup, so you can’t really taste the sweet potato. It’s added more for texture than taste.

• Do you need to refrigerate a cake made with sweet potatoes? The sweet potato is baked into the cake, so you don’t need to refrigerate it, unless you’ve frosted it. Any dessert with a coconut milk whipped topping should be refrigerated.

• How do you store this cake? If it’s unfrosted, you can cut the cake into pieces, place in an airtight container and store at room temperature. You can also wrap the un-cut cake and keep it at room temperature for a few days. If it’s frosted, the cake should be stored in an airtight container in the refrigerator.

• How long will this cake last? The unfrosted cake will last at room temperature for about 4-5 days. The frosted cake is best enjoyed the day it’s made, but it will last for 1-2 days stored in the refrigerator. The coconut whip will firm up a bit so the frosting won’t be as light and fluffy on the second day.

• Can you freeze it? I don’t recommend freezing the cake with the frosting, but the unfrosted cake freezes well. Just let the cake cool completely and then wrap it tightly in plastic wrap. It should last in the freezer for up to 3 months. To defrost, keep the cake in the plastic wrap and defrost in the refrigerator overnight.

Additional tips and substitutions for making this healthy sweet potato cake:

• You’ll need half a cup of mashed sweet potato (about 1 medium-sized potato), so I usually just cook a little extra when I’m preparing them for a meal.

• Make sure your sweet potato is mashed really well. You don’t want any lumps of potato in the cake.

• For the nut milk, I normally use cashew or almond milk, but if you don’t need this cake to be dairy-free, you can use dairy milk.

• While I bake a lot with coconut sugar as it’s less processed, I’ve also tried this cake with granulated and cane sugar, and both work well.

• The batter for this cake is thick. Make sure you spread it out evenly in the pan, and tap the bottom of the pan on the counter to help level out the batter. This will create an even cake with a smooth top.

• The recipe calls for a 9-inch square pan but you can also use an 8-inch. Just increase the bake time by about 5 minutes as it will be a thicker cake. Test for doneness with a toothpick.

Other quick and easy dairy-free cakes you might enjoy:

• Lemon Raspberry Almond Crumb Cake is bursting with juicy raspberries and tart lemon flavour and goes perfectly with a cup of tea or coffee!

• Buttermilk Plum Cake (made Dairy-Free) is lightly spiced with cinnamon and ginger and topped with juicy plums. It’s made in one bowl and requires just 10 minutes prep time.

---

Scale 1x2x3x

Ingredients

For the cake:

• 1 1/2 cups whole wheat flour
• 3/4 cup coconut sugar
• 3 teaspoons ground cinnamon
• 1 teaspoon baking soda
• 1/2 teaspoon kosher salt
• 1 cup unsweetened nut milk
• 1/2 cup mashed sweet potato (about 1 medium potato)
• 1/4 cup extra virgin olive oil

For the coconut whip:

• 2 cans (400 ml) full fat coconut milk, refrigerated (see note)
• 3 tablespoons maple syrup
• 2 tablespoons unsweetened cocoa

---

Instructions

1. Pre-heat oven to 350F and line a 9-inch square pan with parchment paper.
2. In a large bowl, whisk together the flour, sugar, cinnamon, baking soda and salt. Add in the milk, sweet potato and oil, and stir until well combined.
3. Pour the batter into the prepared pan and bake for 24-26 minutes, or until a toothpick inserted in the middle of the cake comes out clean.
4. Remove from oven and let cake cool slightly. Use the edges of the parchment paper to lift the cake out of the pan and onto a wire rack to cool completely.
5. Scoop out the solidified coconut milk into a deep mixing bowl (discard or reserve the coconut water for another recipe). Using an electric mixer, beat the coconut milk on high for about a minute. Scrape down the sides and add the maple syrup and cocoa. Mix on high for a few minutes until the frosting is light and fluffy. Spread the frosting onto the cooled cake.
6. Serve immediately or store in an airtight container in the refrigerator and enjoy within 1-2 days.

Notes

1. Total recipe time includes time to cook the sweet potato and for the cake to cool before frosting.
2. To make the frosting, the coconut milk needs to be refrigerated overnight or preferably for 24 hours to allow the coconut milk solids to separate and solidify. If you’re not sure if they are fully solidified, you can pop the cans in the freezer for a few minutes but be careful they don’t freeze.
3. Be sure to read the Tips and Substitutions section above for more detailed tips and suggestions for variations on the recipe.
