Perfect homemade sponge cake (without baking powder)

A light, fluffy sponge cake is one of the classics of home baking—and believe it or not, you don’t need baking powder to make it rise. The secret lies in the technique: whisking the eggs until airy, gently folding in the flour, and baking patiently at a steady temperature.

This simple recipe shows you exactly how to get a soft, springy sponge that works as the perfect base for fruit cakes, cream-filled tortes, or elegant layered gateaux. Best of all, you can scale the recipe up or down depending on the size of your cake tin.

Why This Sponge Cake Works

  • No baking powder needed: Air whipped into the eggs does all the lifting.
  • Versatile: Flavor it with vanilla, lemon, or orange zest.
  • Reliable: Works with pans from 15 cm (6 in) to 25 cm (10 in).
  • Classic base: Ideal for layering, decorating, or enjoying plain with tea.

Tips for Success

  • Don’t open the oven during the first 30 minutes—this keeps the cake from collapsing.
  • Always sift the flour before folding it into the eggs for maximum lightness.
  • Add vanilla extract or citrus zest for extra flavor.
  • Cool the cake in the pan for 10 minutes, then turn it out onto a wire rack to finish cooling.

Base Recipe Method

  1. Whip the eggs and sugar: Beat together until the mixture triples in volume and becomes pale and foamy.
  2. Add the flour: Sift and gently fold in the flour in two batches, being careful not to knock out the air.
  3. Prepare the pan: Butter and flour your cake tin of choice.
  4. Bake: Place in a preheated oven at 170°C (340°F) until a toothpick inserted in the center comes out clean.
  5. Cool: Rest in the pan for 10 minutes, then remove to a wire rack.
