Ingredients

  • 1½ teaspoons baking powder
  • ¼ teaspoon salt
  • ½ cup unsalted butter, softened
  • ¼ cup brown sugar
  • ½ cup granulated sugar

  • 1 teaspoon vanilla extract
  • ½ cup milk or dairy-free milk

Instructions

  • Preheat the oven to 350°F (175°C).
  • Grease a round cake pan and line the bottom with parchment paper.
  • Melt a small amount of butter and spread it over the bottom of the pan.
  • Sprinkle brown sugar evenly over the butter.
  • Arrange the sliced plums neatly over the sugar layer.
  • In a bowl, whisk together the gluten-free flour blend, almond flour, baking powder, salt, and cinnamon.
  • In a separate bowl, cream the butter and granulated sugar until light and fluffy.
  • Add the eggs one at a time, mixing well after each addition.
  • Stir in the vanilla extract and lemon zest.
  • Gradually add the dry ingredients alternately with the milk, mixing until just combined.
  • Pour the batter gently over the arranged plums and smooth the top.
  • Bake for 40–45 minutes until golden and a toothpick inserted into the center comes out clean.
  • Allow the cake to cool for about 10 minutes before carefully inverting it onto a serving plate.
  • Serve warm or at room temperature.

Notes

Use ripe but firm plums so they hold their shape during baking.A gluten-free flour blend with xanthan gum works best for texture.Do not overmix the batter to keep the cake light and tender.Let the cake cool slightly before inverting to prevent sticking.Serve with whipped cream, yogurt, or vanilla ice cream for an extra special dessert.
