1. Prep & Preheat
Preheat oven to 325°F (160°C).
Line an 8-inch round pan with parchment paper (do NOT grease the sides—this helps the cake rise).
2. Whip Eggs & Sugar (Key for Fluffiness!)
In a heatproof bowl, whisk eggs and sugar.
Place the bowl over a simmering water bath (double boiler), whisking constantly for 2-3 minutes until warm (about 110°F/43°C).
Remove from heat and beat with a mixer for 5-7 minutes until pale, thick, and tripled in volume (ribbon stage).
3. Fold in Dry & Wet Ingredients
Sift flour in 3 batches, gently folding with a spatula after each addition.
In a separate bowl, mix warm milk, oil, and vanilla.
Pour 1/3 of the milk mixture into the batter, folding gently. Repeat twice more.
4. Bake & Cool Properly
Pour batter into the pan and tap lightly to remove bubbles.
Bake 30-35 minutes until golden and a toothpick comes out clean.
Invert the pan immediately (to prevent sinking) and cool completely before removing.

FAQ
Q: Why did my cake sink?
A: Underbaking or overmixing the batter. Ensure proper whipping and baking time.
Q: Can I use all-purpose flour?
A: Yes, but replace 2 tbsp flour with cornstarch for a lighter texture.
Q: Why no butter?
A: Butter weighs down the batter—oil keeps it light while adding moisture.
