Delicious classic vanilla slice recipe with detailed instructions and nutritional information.

  • Total Time: 1 hour 15 minutes
  • Yield: 8 servings 1x

Ingredients

Scale
  • 1 cup all-purpose flour
  • 1/2 cup unsalted butter, cold
  • 2 tablespoons granulated sugar
  • 2 cups whole milk
  • 1 teaspoon vanilla extract
  • 4 egg yolks, room temperature
  • 1/4 cup granulated sugar
  • 1/4 cup cornstarch, sifted
  • 1 tablespoon agar-agar powder

Instructions

  1. Preheat your oven to 180°C (350°F).
  2. In a mixing bowl, combine 1 cup of all-purpose flour and ½ cup of unsalted butter, cutting them together with a pastry cutter until they resemble coarse crumbs.
  3. Add 2 tablespoons of granulated sugar and mix well.
  4. Press this mixture firmly into a greased rectangular baking dish and bake for about 15 minutes until golden brown.
  5. Set aside to cool.
  6. In a medium saucepan over low heat, combine 2 cups of whole milk and 1 teaspoon of vanilla extract.
  7. In another bowl, whisk together 4 egg yolks, ¼ cup of granulated sugar, ¼ cup of cornstarch, and 1 tablespoon of agar-agar powder until smooth.
  8. Gradually pour in the warm milk mixture into the egg mixture while whisking constantly to avoid cooking the eggs.
  9. Return the combined mixture back into the saucepan over medium heat.
  10. Stir continuously as it heats up until it thickens into a pudding-like consistency—this should take about 5-7 minutes.
  11. Once thickened, remove from heat and let it cool slightly before pouring over your cooled pastry base.
  12. Cover your baking dish with plastic wrap once you've poured in the custard layer.
  13. Place it in the refrigerator for at least two hours or until completely set.
  14. After chilling, slice your Classic Vanilla Slice into squares or rectangles using a sharp knife dipped in hot water (for clean cuts!).
  15. Garnish with powdered sugar or fresh berries if you're feeling fancy.
  16. Serve immediately to enjoy all those delightful layers!

Notes

Store in an airtight container.

Reheat gently to maintain texture.

Serve chilled, dusted with icing sugar.

Use fresh vanilla for best flavor.
