INGREDIENTS:

• 10 ounces frozen whole sweet purple yams, thawed
• 9 ounces (about 2 cups) all-purpose flour, plus more for dusting
• 1 1/2 teaspoon baking powder
• 1 1/2 teaspoon kosher salt
• 1/4 teaspoon fresh grated nutmeg
• 1/3 cup granulated sugar
• 2 eggs, lightly beaten
• 1/4 cup canned unsweetened coconut milk
• 2 tablespoons unsalted butter, melted
• Canola oil, for frying
• For the glaze:
• 1/4 cup canned unsweetened coconut milk
• 2 cups powdered sugar

INSTRUCTIONS:

1. Slice the thawed purple yams into 1-inch pieces, then cook in boiling water until tender, 5-10 minutes. Drain the yams, then pass them through a potato ricer and into the bowl of a stand mixer fitted with a paddle attachment.
2. Whisk together the flour, baking powder, salt, and nutmeg in a large bowl and set aside.
3. To the bowl of the stand mixer, add the granulated sugar, eggs, coconut milk, and butter, then mix on low until smooth. With the motor running, slowly add the dry ingredients to the wet ingredients and mix until well combined. Let dough rest 10 minutes.
4. Heat 2-inches of oil in a large cast-iron skillet over medium-high heat until the oil reaches a temperature of 370 degrees on a deep-fry thermometer.
5. While the oil is heating, transfer the dough to a lightly floured work surface. The dough will be sticky at this point, so sprinkle a bit more flour over the dough as well. Using your hands, pat the dough out into a 10-inch round about 1/2-inch thick.
6. Using a floured 3-inch doughnut cutter, cut out the doughnuts. Gather any remaining scraps, pat them out again, and cut more doughnuts.
7. Working in batches, place the doughnuts, and doughnut holes, into the hot oil. Fry, flipping over once, until puffed and golded, 3-4 minutes. Using tongs, transfer the doughnuts to a large plate lined with paper towels.
8. To make the glaze:
9. In a medium bowl, whisk together the coconut milk and powdered sugar until a glaze is formed. While the doughnuts are still warm, dip them into the glaze, then let them drain on a wire rack set over a baking sheet. Serve immediately.
