Naomi Pomeroy likes cooking with dried fruit because it’s easy to keep on hand. “Fresh fruit goes bad so quickly,” she says. She poaches dried, local plums, then mixes them with a brown sugar caramel to make a topping for individual olive-oil cakes. Instead of prunes, try peach slices or apple chunks.

Topping

  1. 1 cup granulated sugar
  2. 1 1/2 cups dry white wine
  3. 1 vanilla bean
  4. 1 cinnamon stick
  5. Three 1-inch-thick strips of orange zest
  6. 32 large pitted prunes (about 3/4 pound)
  7. 3/4 cup light brown sugar
  8. 1 teaspoon unsalted butter

Cakes

  1. 1/4 cup fresh orange juice
  2. 1/4 cup low-fat buttermilk
  3. 3 large eggs
  4. 2/3 cup extra-virgin olive oil
  5. 1 cup granulated sugar
  6. 3/4 cup fat-free Greek-style plain yogurt
  7. 1 3/4 cups all-purpose flour
  8. 1 1/2 teaspoons baking powder
  9. 1/4 teaspoon baking soda
  10. 1 teaspoon salt
  1. MAKE THE TOPPING Preheat the oven to 350°. In a medium saucepan, combine the granulated sugar, white wine, vanilla bean, cinnamon stick, orange zest and 3 cups of water and bring to a boil. Simmer over moderate heat for 10 minutes. Add the prunes and simmer over moderately low heat until plumped and tender but not falling apart, about 25 minutes. Using a slotted spoon, transfer the prunes to a plate to cool.
  2. Coat eight 1-cup ramekins with vegetable oil spray and set them on a sturdy rimmed baking sheet.
  3. In a small saucepan, combine the brown sugar and butter with 1/4 cup of water and bring to a boil, stirring to dissolve the sugar. Let cool slightly. Divide the caramel and poached prunes among the ramekins.
  4. MAKE THE CAKES In a medium bowl, whisk the orange juice with the buttermilk, eggs, oil, granulated sugar and 1/4 cup of the yogurt. In a large bowl, whisk the flour with the baking powder, baking soda and salt. Whisk the egg mixture into the dry ingredients until smooth. Divide the batter among the ramekins, filling them a little more than half full. Spray a sheet of parchment paper with vegetable oil spray and invert it over the ramekins. Set another baking sheet on the parchment.
  5. Bake the cakes for about 1 hour and 10 minutes, until a tester inserted in the centers comes out clean. Let the cakes cool for 10 minutes, then run a thin knife around the edges and invert them onto plates, allowing any caramel in the ramekins to drip over the cakes. Spoon a dollop of the remaining 1/2 cup of yogurt on top of each cake and serve.
Make Ahead

The prunes can be poached up to 2 days ahead and refrigerated in their poaching liquid. The unmolded cakes can stand at room temperature for up to 6 hours before serving.
