The Airy Blue-Ribbon Cake: Butter-Free Genoise with Blueberry-Chia Pudding

I have been experimenting in the kitchen again! I wanted to see if I could create a dessert that felt incredibly indulgent but skipped the heavy butter and refined creams.

The result? This Butter-Free Genoise. It’s a classic French sponge that relies entirely on whipped eggs for its lift. I’ve layered it with a homemade “pudding” made from Greek yogurt, chia seeds, and simmered blueberries. It’s bright, tangy, and holds its shape beautifully.

Part 1: The Classic Butter-Free Genoise

Yields: 8-inch round cake

The Goods (By Weight)

• 200g Large Eggs (approx. 4 eggs)
• 120g Granulated Sugar
• 120g Cake Flour (Or 105g AP flour + 15g cornstarch, sifted twice)
• Pinch of Salt
• 5ml Vanilla Extract
• 15–20g Neutral Oil (Canola or Grapeseed) — Optional, but helps keep the sponge moist!

The Method

1. Prep: Preheat oven to 170°C (340°F). Line the bottom of your 8-inch pan with parchment, but do not grease the sides – the batter needs to “climb” the walls to get that height!
2. Warm the Eggs: Place eggs, sugar, and salt in a heatproof bowl over a pot of gently simmering water (don’t let the bowl touch the water). Whisk until the mixture is lukewarm (~40°C). This dissolves the sugar and helps the eggs whip to a massive volume.
3. Whip It Good: Move to a mixer with the whisk attachment. Whip on medium-high for 5–7 minutes until the batter is pale, tripled in volume, and leaves a “ribbon” that sits on the surface for 3 seconds.
4. The Gentle Fold: Sift your flour over the eggs in three additions. Use a spatula to fold very gently, cut through the center, lift, and rotate the bowl. Stop the second the flour disappears.
5. The Oil Hack: If using oil, stir 1 cup of batter into the oil first, then fold that mixture back into the main bowl. This prevents the oil from sinking and deflating your hard-earned air bubbles!
6. Bake: Pour immediately and bake for 22–28 minutes. Don’t peek! It’s done when it springs back and slightly pulls away from the edges.

The high-protein, fiber-packed alternative to cream.

The Goods

• 1 to 1 ½ cups 0% Greek Yogurt (strained/thick is best)
• ¾ to 1 cup Blueberries (fresh or frozen)
• 1–2 tbsp Chia Seeds
• Optional: A splash of vanilla or a drizzle of honey if you want a bit more sweetness.

The Method

1. Reduce the Berries: Simmer blueberries in a small pan for 5–8 minutes until they break down and the liquid evaporates slightly. This creates a concentrated “jam” base. Cool completely.
2. Thicken: Stir the cooled berries into the yogurt. Add 1 tbsp of chia seeds and chill for 30 minutes.
3. The Texture Check: If it’s thick and spreadable, you’re ready. If it still feels loose, stir in another ½ tbsp of chia seeds and wait 10 more minutes. The chia seeds act as a natural stabilizer to keep your layers from sliding!

Why This Experiment Worked

• The Sponge: By warming the eggs, we get a stable structure without needing chemical leaveners or heavy fats.
• The Filling: Simmering the berries prevents the yogurt from getting “watery,” and the chia seeds add a lovely pudding-like texture along with Omega-3s and fiber.
