Equipment

  • Mixing bowls
  • Electric mixer or whisk
  • 9x13-inch baking pan or square pan
  • Parchment paper
  • Measuring cups & spoons

Ingredients
  

  • 1 cup all-purpose flour (or almond flour for gluten-free)
  • ½ cup unsalted butter, melted
  • 1 cup granulated sugar
  • 4 large eggs (room temperature)
  • 2 cups milk
  • 1 tsp vanilla extract
  • 1½ cups fresh or frozen blueberries (tossed in 1 tbsp flour)
  • Optional: zest of 1 lemon, powdered sugar for garnish

Instructions
 

  • Prepare Pan: Line baking pan with parchment paper.
  • Make Sponge Base: Beat eggs and sugar until pale and fluffy. Fold in flour and melted butter. Spread evenly in pan.
  • Custard Layer: Whisk milk, eggs, sugar, and vanilla until smooth. Pour gently over sponge batter.
  • Add Blueberries: Toss berries in flour, then scatter evenly over custard layer.
  • Bake: Bake at 325°F (160°C) for 45–50 minutes until custard is set but slightly jiggly.
  • Cool: Let cake cool completely to allow custard to firm.
  • Serve: Slice into squares or wedges. Garnish with powdered sugar or whipped cream.

Notes

  • Toss blueberries in flour to prevent sinking.
  • Bake gently—custard should be silky, not rubbery.
  • Cool fully before slicing for neat presentation.
  • Store in fridge up to 3 days; freeze slices for up to 2 months.
  • Add lemon zest or swap berries for raspberries for creative twists.
