Ingredients
Makes one 9-inch cake
- 2 cups roasted and mashed sweet potato (about 2 medium sweet potatoes)
- 4 large eggs, at room temperature
- 1 cup brown sugar or coconut sugar
- 1/2 cup plain yogurt or full-fat Greek yogurt
- 1/3 cup neutral oil (canola, vegetable, or light olive oil)
- 2 tsp baking powder
- 1 tsp baking soda
- 1 1/2 tsp ground ginger (or 2 tsp freshly grated)
- 1 tsp ground cinnamon
- 1/4 tsp ground nutmeg
- 1/2 tsp fine sea salt
- 1 tsp vanilla extract
- Zest of 1 orange (optional for brightness)
- Powdered sugar or a simple glaze for finishing (optional)
Step-by-step instructions
- Preheat and prep: Preheat your oven to 350°F (175°C). Grease and line a 9-inch springform pan or cake pan, or use parchment paper for easy release.
- Roast the sweet potatoes: If you haven’t already, roast whole sweet potatoes at 400°F until tender (about 45–60 minutes). Let cool, peel, and mash until smooth. You can also microwave them for a quicker option.
- Whisk wet ingredients: In a large bowl, whisk the eggs and sugar until combined. Add the mashed sweet potato, yogurt, oil, and vanilla, whisking until smooth and uniform.
- Combine dry ingredients: In a separate bowl, stir together baking powder, baking soda, ground ginger, cinnamon, nutmeg, and salt.
- Fold together: Add the dry mix to the wet mixture and fold gently until you can’t see streaks of flourless batter. Stir in orange zest if using.
- Bake: Pour batter into the prepared pan and smooth the top. Bake for 35–50 minutes, depending on your pan and oven, until the cake is set and a toothpick inserted near the center comes out mostly clean with a few moist crumbs.
- Cool and finish: Let the cake cool in the pan for 15 minutes, then transfer to a wire rack. Dust with powdered sugar, brush with a simple glaze, or serve plain with whipped cream.

Tips for success
- Measure mashed sweet potato by weight when possible for consistent results; 2 cups is about 400–450 grams.
- Don’t overmix: because this cake is flourless, gentle folding keeps it tender rather than dense.
- Check doneness: ovens vary — start checking at 30 minutes and watch for the top to set without overbrowning.
- Room-temperature eggs and yogurt help the batter emulsify smoothly.
- Add texture: fold in a handful of chopped walnuts or pecans for crunch.
