Description

This Plum Upside-Down Cake features caramelized plums layered under a moist, buttery cake. It’s an elegant yet easy dessert that flips into a showstopper with every slice.


Ingredients

Scale
  • 1/2 cup unsalted butter (plus extra for greasing)
  • 2/3 cup brown sugar
  • 4 to 5 fresh plums, sliced
  • 1 1/2 cups all-purpose flour
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon salt
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup whole milk


Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan and line the bottom with parchment paper.
  2. In a saucepan, melt 1/2 cup butter and brown sugar over medium heat until bubbly. Pour into the prepared pan and spread evenly.
  3. Arrange sliced plums in a single layer over the caramel mixture.
  4. In a bowl, whisk together flour, baking powder, and salt.
  5. In another bowl, cream remaining butter with granulated sugar until fluffy. Beat in eggs one at a time, then add vanilla.
  6. Add the dry ingredients to the wet mixture in batches, alternating with milk, until combined.
  7. Gently spread the batter over the plums, smoothing the top evenly.
  8. Bake for 40–45 minutes or until a toothpick inserted in the center comes out clean.
  9. Cool in the pan for 10–15 minutes, then run a knife around the edges and invert onto a serving plate.
  10. Serve warm or at room temperature, optionally with ice cream or whipped cream.

Notes

  • Use ripe but firm plums to avoid soggy texture.
  • Don’t skip the parchment paper to ensure a clean flip.
  • Try adding cinnamon or cardamom to the batter for extra warmth.
  • The cake keeps well and is perfect for make-ahead entertaining.
