Cinnamon Sponge Cake

The secret to sponge cake is air: millions of tiny bubbles beaten into the eggs expand in the heat, lifting the batter into a fluffy cloud. This cinnamon version adds a warm, comforting twist to the classic recipe, making it perfect on its own with a dusting of powdered sugar.

Instructions

1

Preheat oven to 350°F (180°C). Line your baking pan with parchment paper.

Tip: If you lack parchment, grease and flour the pan, tapping out excess flour.
2

Beat eggs, sugar, and salt in a large bowl with an electric mixer on high for 5-8 minutes until thick, pale, and tripled in volume.

Tip: This step incorporates air. It's ready when the batter falls in a ribbon pattern (ribbon stage).
3

While mixing slowly, drizzle in the milk, melted butter, and vanilla.

Tip: The butter should be liquid but not hot, or it will scramble the eggs.
4

Sift together flour, baking powder, and cinnamon, then sift this over the egg mixture.

Tip: Sifting prevents lumps.
5

Gently fold the flour in with a spatula using large, circular motions. Do not beat; just fold to keep the air in.

Tip: The goal is to keep the fluffiness.
6

Pour into the pan and bake for 25-30 minutes.

Tip: If the center jiggles, it needs more time.
7

Test with a toothpick; if it comes out clean, it's done. Cool in the pan, then on a wire rack.

Tip: Cooling on a rack prevents a soggy bottom.

Recipe FAQ

Why did it collapse?
You might have opened the oven too early or overmixed the flour, knocking out the air bubbles.
When can I slice it?
Only when completely cool! Cutting it hot will result in a gummy texture.
