Flourless sweet potato ginger cake is a soft, moist dessert with warm spices and no wheat flour at all. Mashed sweet potato and eggs form the base, while ginger and cinnamon give each slice a gentle kick.
The batter comes together in one bowl with a whisk, and the baked round slices neatly after cooling. It suits anyone avoiding wheat, and it works for dessert, brunch, or an afternoon coffee.

Why This Flourless Sweet Potato Ginger Cake Recipe Works
Sweet potato adds natural sweetness and moisture, so the cake needs very little sugar and stays tender without any flour.
Eggs provide structure and lift, and whisking them well with the maple syrup creates a light, even crumb.
Fresh ginger and cinnamon bring warmth that balances the earthy sweet potato and makes the flavor feel rounded.
Ingredients for Flourless Sweet Potato Ginger Cake
- 1 cup cooked mashed sweet potato, cooled slightly
- 3 large eggs
- 1/3 cup maple syrup or honey
- 2 tablespoons melted coconut oil or melted butter
- 1 teaspoon vanilla extract
- 1 teaspoon grated fresh ginger, or 1/2 teaspoon ground ginger
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/2 teaspoon baking powder
- 1 pinch salt
Sweet potato. Bake or steam the potatoes until very soft, then mash until no lumps remain so the batter bakes smooth.
Eggs. Room temperature eggs whisk up lighter, so set them out for about twenty minutes before you begin.
Sweetener. Maple syrup tastes mellow and warm, and honey also works if no young children will eat the cake.
Fat. Coconut oil keeps the cake dairy free, while melted butter gives a slightly richer flavor.
Ginger. Fresh ginger tastes brighter than ground, so use the smaller amount of ground ginger if that is what you have.
How to Make Flourless Sweet Potato Ginger Cake
1. Prepare the pan Heat the oven to 350 degrees F, then grease an 8 inch round pan and line the bottom with parchment paper.
2. Whisk the base Whisk the mashed sweet potato, eggs, maple syrup, melted oil, and vanilla in a large bowl until the batter looks smooth.
3. Add the spices Stir in the ginger, cinnamon, nutmeg, baking powder, and salt until the mixture looks even and fragrant.
4. Fill the pan Pour the batter into the pan and smooth the top with a spatula, then tap the pan gently to release air bubbles.
5. Bake the cake Bake for 25 to 30 minutes, until the center springs back and a thermometer reads 160 degrees F.
6. Cool in the pan Cool the pan on a rack for ten minutes, then run a knife around the edge and wait until the cake feels barely warm.
7. Slice and serve Turn the cake out onto a plate, flip it right side up, and cut it into eight slices with a sharp knife.
How to Serve Flourless Sweet Potato Ginger Cake
Serve each slice with a spoonful of Greek yogurt or whipped cream and a pinch of cinnamon. For a dinner dessert, offer it next to dark chocolate mousse or fresh fruit pavlova. A glass of fresh peach lemonade cuts the richness, and mango panna cotta makes a lighter pairing.
How to Store and Reheat Flourless Sweet Potato Ginger Cake
Cool the cake within two hours, then cover and refrigerate for three to four days. For longer storage, wrap slices tightly and freeze for up to one month, then thaw overnight in the refrigerator and serve cold or slightly warm.
Tips and Variations for Flourless Sweet Potato Ginger Cake
Flag the allergens. The cake contains egg, and the coconut oil or butter swap affects guests with coconut or milk allergies, so label it clearly.
Cook the eggs fully. Bake until the center reaches 160 degrees F, since a flourless batter can look set while the middle is still soft.
Cool the potato. Hot mashed potato can scramble the eggs, so let it cool for ten minutes before whisking.
Keep honey away from babies. If you choose honey, remember it is not safe for children under one year old.
Line the pan. Parchment on the bottom prevents sticking, because a flourless batter clings to bare metal.
Add texture. Fold in a handful of chopped pecans or walnuts for crunch, and flag the tree nuts for guests.
Mash well. Use a potato masher or a food processor so the batter has no strings or lumps.
Check trusted guidance. For general advice on eggs and safe handling, read the Montana State University Extension egg fact sheet.
