Healthy Sweet Potato Chocolate Cake

This flourless sweet potato chocolate cake is full of rich chocolate flavor with a tender moist crumb and a glossy ganache that makes every bite feel decadent. I keep coming back to this recipe whenever I want a dessert that feels like a treat but fits into a healthier lifestyle. You would never guess there is sweet potato inside and it all comes together quickly with just one bowl.

I first made this cake for a friend's birthday when we were both avoiding processed sugar and it was such a hit it quickly became the only chocolate cake my family asks for. The ganache really brings it together and turns it from a healthy snack into a true dessert.

Step-by-Step Instructions

Prep the Sweet Potato:

Cook the sweet potato in the microwave until fully tender turning halfway through the cook time. Allow it to cool completely before peeling so the flesh comes out creamy and there is no heat left to scramble your eggs.

Mash and Measure:

Scoop out the cooked flesh of the sweet potato mash until smooth and creamy and measure exactly one cup. Too much sweet potato can make the cake dense.

Mix Wet Ingredients:

In a large bowl combine the mashed sweet potato almond butter eggs maple syrup vanilla and vinegar. Stir together until the mixture is thick and glossy. If almond butter is stiff microwave just until pourable for easier mixing.

Incorporate Dry Ingredients:

Add cocoa powder baking soda cinnamon if using and salt to the bowl. Stir or whisk until a thick smooth batter forms with no dry pockets. For more intense chocolate flavor fold in chocolate chips now.

Prepare the Pan:

Line a nine inch square or round cake pan with parchment paper for easy removal or lightly grease if needed. Spread batter evenly into the pan so the cake bakes level.

Bake the Cake:

Place the cake on the center rack and bake at three hundred fifty degrees Fahrenheit for about twenty five minutes until the top springs back lightly and a tester comes out mostly clean. Aim for an internal temperature of one hundred ninety to two hundred five degrees for perfect doneness.

Make the Ganache:

A few minutes before the cake finishes combine chocolate chips coconut milk and coconut oil in a bowl. Microwave in short bursts stirring until glossy and smooth. Spread warm ganache over the cake while still warm for a silky shiny finish.

Cool and Slice:

Let the cake cool at room temperature. For faster cooling and to set the ganache transfer to the fridge. Slice into even squares or wedges and enjoy.

Sweet potato is my favorite secret ingredient in this cake. It keeps the crumb so silky and blends in completely so nobody guesses they are eating a veggie cake. I sometimes make this with my niece who loves to help with the mashing step and proudly tells everyone there is a hidden orange vegetable in her chocolate cake.

Storage Tips

Store any leftovers in an airtight container in the fridge to keep the cake moist for up to one week. This cake also freezes beautifully just wrap portions tightly and thaw overnight in the fridge or at room temperature. The ganache stays smooth and glossy after freezing too.

Ingredient Substitutions

If you do not need the cake to be dairy free swap the coconut milk in the ganache for half and half or heavy cream. Any nut or seed butter will work instead of almond butter just make sure it is creamy and unsweetened. Honey can be used in place of maple syrup although the flavor will be a little different.

Serving Suggestions

Top cake squares with a dollop of coconut whipped cream or a sprinkle of chopped nuts for added crunch. Serve chilled for a fudge like texture or at room temperature for a softer crumb. I love to set out extra ganache or some fresh berries on the side for a special finish at dinner parties.
