🛒 Ingredients

19 servings

19
  • 1 large egg
  • 1 cup (200 g) granulated sugar
  • 2 tablespoons softened margarine or butter
  • 3 cups (375 g) all-purpose flour, sifted
  • 1 tablespoon baking powder
  • 1 cup (240 ml) whole milk

Directions

  1. 1

    Preheat your oven to 350°F (180°C). Grease and flour a 9x13-inch (30 cm) baking pan.

  2. 2

    In a large bowl, beat the egg with the sugar until pale and slightly creamy. Mix in the softened margarine until fully combined.

  3. 3

    Gradually fold in the sifted flour and baking powder, alternating with the milk, stirring until the batter is smooth and lump-free.

  4. 4

    Pour the batter into the prepared pan and bake for 30 to 35 minutes, or until golden brown. Insert a toothpick into the center — it should come out clean when ready.

💡 Chef's Tip

For extra flavor, stir in a teaspoon of vanilla extract or a pinch of cinnamon. Once cooled, dust with powdered sugar or drizzle with a simple lemon glaze for a lovely finish.
