Instructions
1. Prepare the Oven and Pan
- Preheat oven to 170°C (340°F).
- Grease and line the bottom of your chosen cake pan with parchment paper.
2. Whip the Eggs and Sugar
- Place the eggs and sugar in a large mixing bowl.
- Beat with a hand mixer or stand mixer on high speed for 8–10 minutes, until the mixture is pale, thick, and tripled in volume.
- You should be able to draw a “ribbon” with the batter that stays on top for a few seconds.
3. Fold in the Flour
- Sift the flour over the egg mixture in small batches.
- Gently fold with a spatula, using light sweeping motions to avoid deflating the batter.
4. Bake
- Pour the batter into the prepared pan.
- Smooth the top with a spatula.
- Bake according to pan size, usually 25–35 minutes, until golden and springy to the touch.
- Insert a toothpick into the center—if it comes out clean, the cake is ready.
5. Cool
- Let the cake cool in the pan for 5 minutes.
- Remove and place on a wire rack to cool completely.
Tips for Success
✅ Use room temperature eggs for maximum volume.
✅ Whip the eggs and sugar until they are very thick and airy—this is the natural leavening.
✅ Fold the flour very gently to keep the batter fluffy.
✅ Don’t open the oven door in the first 20 minutes of baking or the cake may collapse.
Serving Suggestions
- Dust with powdered sugar for a simple tea-time treat.
- Slice and fill with whipped cream and fresh berries.
- Use as a base for layered cakes with frosting or ganache.
- Serve with custard or fruit syrup for a light dessert.
