Directions

1. Preheat your oven to about 160‑170 °C. Prepare a chiffon or tube pan; do not grease the sides.

2. Separate eggs: yolks in one bowl, whites in another.

3. In the yolk bowl, whisk together yolks and some sugar until pale. Add oil, milk, and vanilla; mix until combined. Sift in cake flour; gently stir until just smooth.

4. In the whites bowl, add cream of tartar and begin whipping on medium speed. Once foamy, gradually add sugar in portions until you reach stiff peaks.

5. Gently fold about one‑third of the meringue (whipped egg whites) into the yolk batter to lighten it. Then fold in the remaining meringue in two portions, being careful to keep as much air as possible.

6. Divide the batter equally into as many portions as you have colors. Add a different food coloring to each portion; stir gently to combine.

7. Layer the colored batters one by one into the cake pan(s), smoothing lightly between layers. Tap the pan a few times to release large air bubbles.

8. Bake in the preheated oven until the top springs back when touched lightly, or a skewer inserted into the center comes out clean. Baking time will depend on pan size and oven (often around 40‑60 minutes for a typical layer cake in a tube or round pan).

9. Once baked, invert the cake immediately while hot and allow to cool completely upside down before removing from the pan.

• Prep time: ~ 30 minutes (including mixing, coloring, layering)

• Baking time: ~ 45‑60 minutes

• Cooling time: ~ 1 hour

Variations

• Pastel rainbow: Use pastel shades—use very little coloring for softer hues.

• Natural colors: Use powders or natural colorants (matcha, beet powder, turmeric, etc.) instead of synthetic food coloring.

• Flavored layers: Add extracts to specific colored layers (lemon for yellow, peppermint for green, etc.).

• Frosted version: Frost with buttercream, whipped cream, or cream cheese; you can also do a crumb coat layer.

• Hidden rainbow inside: Bake plain outside but slice to reveal rainbow layers inside.

Storage/Reheating

• Store at room temperature in a sealed container for 1‑2 days if using no perishable frosting.

• If frosted with cream or buttercream, keep refrigerated; bring to room temperature before serving.

• Cake layers can be wrapped tightly and frozen; thaw overnight in the fridge when ready to use.

• To refresh slightly stale cake, warm slices very gently (e.g. in microwave for a few seconds or in warm oven) and serve with a little cream.

FAQs

What is chiffon cake and how is it different from sponge cake?

Chiffon cake uses oil rather than butter (or minimal butter) and also separates eggs, whipping the whites separately. This results in a moist yet airy texture with a tender crumb. Sponge cake typically has no oil and often relies more on beaten whole eggs or yolks + whites together for structure.

Can I use regular flour instead of cake flour?

You can, but the texture might be slightly denser. Cake flour has lower protein, which helps make the cake softer. If using all‑purpose flour, you might consider replacing some with cornstarch to mimic cake flour.

How do I avoid colors bleeding between layers?

Let each layer settle briefly before adding the next. Gently level the batter before adding the next color to minimize mixing. Also, tap the pan to release air so layers stay distinct.

My cake sank in the middle—why?

Common reasons include: underbaking, opening the oven too early, overmixing or deflating the meringue, or a weak oven temperature. Be sure to bake fully and handle the batter gently.

Can I reduce the number of colors?

Yes. Using fewer colors is fine. The layering and effect still work with 3‑4 colors. Adjust amounts so all batters are similar in volume.

How do I know when egg whites are at stiff peaks?

When you lift the beater out of the whites, the peak should stand upright and not fold over much. The meringue should be glossy, not dry, and should hold shape.

Does the pan need special treatment?

Do not grease the sides of a chiffon cake pan. This allows the cake to climb up and cling to the sides, which helps it rise. Greasing may cause collapsing.

Can I bake this in smaller/single pans instead of layering?

Yes. You can bake colored batters in separate smaller pans, then stack with frosting between layers. Or bake in one large pan and swirl the batter for a marbled look.

What kind of food coloring is best?

Gel or paste food colorings are preferred because they impart vivid color without adding too much liquid. Natural powders work too but may produce softer tones and sometimes alter moisture slightly.

Is this recipe suitable for people with dietary restrictions (gluten, dairy, etc.)?

To adapt: use gluten‑free cake flour blend; dairy milk can be substituted with plant‑based milk; for egg allergies, it’s harder because eggs are central to chiffon structure—egg replacers often don’t replicate the same texture.
