20 servings

20
  • 4 eggs
  • 2 cups (400 g) granulated sugar
  • 2 tablespoons softened unsalted butter
  • 1 teaspoon vanilla extract (optional)
  • 1 cup (250 ml) whole milk
  • 4 cups (500 g) all-purpose flour
  • 2 tablespoons baking powder
  • Streusel: 1 cup (200 g) granulated sugar
  • Streusel: 1 cup (120 g) all-purpose flour
  • Streusel: ground cinnamon to taste
  • Streusel: 3 tablespoons softened unsalted butter

Directions

  1. 1

    Preheat oven to 180 °C (350 °F). Grease and flour a large baking pan.

  2. 2

    Beat eggs, sugar, and butter in a stand mixer on medium speed until pale and creamy.

  3. 3

    Add vanilla extract if desired and mix briefly.

  4. 4

    Pour in the milk in a steady stream, beating on low speed until fully combined.

  5. 5

    Add flour gradually, mixing well after each addition and scraping the bowl with a spatula.

  6. 6

    Stir in the baking powder and beat for 30 more seconds.

  7. 7

    Pour batter into the prepared pan and smooth the surface.

  8. 8

    Make the streusel: rub sugar, flour, cinnamon, and butter together with your fingertips until the mixture resembles coarse crumbs.

  9. 9

    Sprinkle streusel evenly over the batter.

  10. 10

    Bake for 35–40 minutes until a toothpick inserted in the center comes out clean. Cool for 15 minutes before slicing.

💡 Chef's Tip

For an even crunchier topping, mix a handful of rolled oats into the streusel. Start checking for doneness at 30 minutes as ovens vary.
