Sweet potatoes give this simple cake a rich, yet still light flavor and crumb. Yellow sweet potatoes are the traditional choice, but we preferred it with orange-fleshed sweet potatoes. Both unrefined and refined coconut oil work; the former has a richer, more intense flavor and aroma that accentuate the shredded coconut in the cake. You'll need a food processor with at least an 11-cup capacity to accommodate the sweet potato puree.

12 ounces orange-fleshed sweet potatoes, peeled and cut into 1-inch chunks
195 grams (1½ cups) all-purpose flour
50 grams (⅔ cup) unsweetened shredded coconut
2 teaspoons ground ginger
2 teaspoons baking powder
1/2 teaspoon baking soda
1 teaspoon kosher salt
200 grams (1 cup) packed dark brown sugar
1 tablespoon grated lime zest, plus 2 tablespoons juice (1 to 2 limes)
3 large eggs
3/4 cup whole milk
1 tablespoon vanilla extract
100 grams (½ cup) coconut oil, melted and warm, plus more for pan
90 grams (¾ cup) powdered sugar
