Blender Sponge Cake

Ingredients

  • 4 large eggs
  • 1 cup (200g) granulated sugar
  • 1 cup (240ml) whole milk (room temperature)
  • ½ cup (120ml) vegetable oil (e.g., canola or sunflower)
  • 2 cups (240g) all-purpose flour
  • 1 tbsp baking powder
  • 1 tsp vanilla extract
  • Zest of 1 lemon or orange (optional, for added aroma)
  • Pinch of salt

Instructions

  1. Preheat the oven:
    Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round or square cake pan (or line with parchment paper).
  2. Blend wet ingredients:
    In a blender, combine eggs, sugar, milk, oil, vanilla extract, and zest (if using). Blend on medium speed for 1–2 minutes until well combined and slightly frothy.
  3. Add dry ingredients:
    Add flour, baking powder, and a pinch of salt to the blender. Pulse or blend in short bursts until fully incorporated and smooth. Do not overmix.
  4. Pour into the pan:
    Pour the batter into your prepared cake pan. Tap the pan gently on the counter to remove any air bubbles.
  5. Bake:
    Bake in the preheated oven for 35–40 minutes or until a toothpick inserted in the center comes out clean.
  6. Cool and serve:
    Allow the cake to cool in the pan for 10–15 minutes, then remove and let it cool completely on a wire rack. Dust with powdered sugar or frost as desired.

Optional toppings:

  • Powdered sugar
  • Whipped cream and fresh fruit
  • Dulce de leche drizzle
  • Chocolate glaze
