Ingredients

Scale
  • 1/4 cup (50g) granulated sugar
  • 2 tablespoons unsalted butter, melted
  • 1 cup chopped rhubarb (about 150g), fresh or frozen (thawed and drained if frozen)
  • 1 1/4 cups (150g) all-purpose flour
  • 1 teaspoon baking powder
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon ground cardamom
  • 1/4 teaspoon salt
  • 1/2 cup (100g) granulated sugar
  • 1/4 cup (60ml) vegetable oil
  • 1 large egg, room temperature
  • 1/2 cup (120ml) plain yogurt or sour cream
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat oven to 350°F (175°C). In a 9-inch round cake pan, combine 1/4 cup granulated sugar and melted butter. Spread evenly over the bottom.
  2. Arrange chopped rhubarb evenly on top of the butter-sugar layer.
  3. In a large bowl, whisk together flour, baking powder, baking soda, ground cardamom, and salt until well combined.
  4. Add sugar, vegetable oil, egg, yogurt, and vanilla extract to the dry ingredients. Stir gently until just combined, avoiding overmixing.
  5. Spoon batter over the rhubarb layer, spreading evenly but leaving some texture visible.
  6. Bake on the middle rack for 35-40 minutes or until a toothpick inserted in the center comes out clean.
  7. Let the cake cool in the pan for 10-15 minutes, then invert onto a serving plate.
  8. Serve warm or at room temperature, optionally with whipped cream or vanilla ice cream.

Notes

If rhubarb is very tart, sprinkle a teaspoon of sugar over it before adding batter. Use fresh rhubarb for better texture; frozen must be thawed and drained well. Toast and grind cardamom pods fresh for best flavor. Avoid overmixing batter to keep cake tender. Grease pan well and butter with sugar topping to prevent sticking. Start checking cake at 35 minutes to avoid burning.
