Description

This Rhubarb Custard Cake is a delightful dessert that perfectly balances the tartness of rhubarb with a rich, creamy custard layer. The soft and moist cake base, infused with vanilla, complements the tangy rhubarb, while the custard adds a smooth, velvety texture. This recipe is easy to follow and makes for a comforting spring or summer treat. Serve it warm with a dollop of whipped cream or a scoop of vanilla ice cream for the ultimate indulgence.


Ingredients

Scale

For the Cake:

  • 200g all-purpose flour
  • 5g baking powder
  • 2g baking soda
  • ¼ teaspoon salt
  • 150g granulated sugar
  • 3 large eggs
  • 120ml vegetable oil
  • 5ml vanilla extract
  • 120ml milk
  • 300g rhubarb, chopped into small pieces
  • 100g custard powder (or vanilla pudding mix)

For the Custard Layer:

  • 300ml milk
  • 2 tablespoons custard powder (or vanilla pudding mix)
  • 50g sugar

Instructions

  • Preheat the Oven: Set your oven to 175°C (350°F). Grease and flour a 9-inch round cake pan to prevent sticking.
  • Mix Dry Ingredients: In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  • Prepare Wet Ingredients: In a large bowl, beat sugar, eggs, vegetable oil, and vanilla extract until smooth. Stir in the milk.
  • Combine the Batter: Gradually fold the dry ingredients into the wet mixture, stirring until just combined. Avoid overmixing.
  • Add Rhubarb: Gently fold in the chopped rhubarb until evenly distributed.
  • Prepare the Custard: In a small saucepan, whisk together milk, custard powder, and sugar over medium heat. Cook, stirring constantly, until the mixture thickens into a smooth custard.
  • Layer the Cake: Pour the cake batter into the prepared pan and smooth the top. Pour the custard over the batter and swirl gently with a spoon.
  • Bake: Place in the oven and bake for 35–40 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
  • Cool and Serve: Allow the cake to cool for at least 15 minutes before slicing. Serve warm or at room temperature with whipped cream or ice cream.

Notes

  • If using frozen rhubarb, thaw and drain excess liquid before adding it to the batter.
  • Substitute almond milk for regular milk for a dairy-free alternative.
  • Sprinkle a bit of cinnamon over the cake before baking for extra warmth and flavor.
