- In a separate bowl, whisk together:
- 3 large eggs
- 1 cup whole milk
- ½ cup sugar
- 1 tablespoon flour
- 1 tsp vanilla extract
- A pinch of salt
- Whisk thoroughly until smooth with no lumps.
Step 4: Layer the Batter
- Pour the custard mixture evenly into the prepared baking dish.
- Carefully spoon the cake batter over the top in small amounts, spreading it gently without mixing the two layers.
Important: Do not stir or swirl. The separation during baking is what creates the magical three-layer effect.
Step 5: Bake to Perfection
- Bake for 40 to 45 minutes, or until the top is golden and a toothpick inserted into the top cake layer comes out clean.
- Rotate the pan halfway through for even baking.
Step 6: Cool and Serve
- Let the cake cool in the pan for 15–20 minutes.
- For best results, refrigerate for a few hours—or even overnight—before slicing. This allows the custard layer to fully set.
Serving Suggestions
- Dust with powdered sugar
- Serve with fresh berries
- Drizzle with caramel or chocolate sauce
- Add a dollop of whipped cream or vanilla ice cream for an extra indulgent treat
Tips for Success
- Don’t Mix the Layers: The cake and custard layers must remain separate. Their different densities are what create the magical layers during baking.
- Use Room-Temperature Eggs: Cold eggs don’t incorporate as smoothly and can affect the batter’s texture and layering.
- Chill Before Slicing: Patience pays off. Refrigerating the cake helps the layers firm up, making it easier to slice and enhancing the texture.
- Adjust Sweetness: If you prefer less sweet desserts, you can reduce sugar in either layer by 2–3 tablespoons.
- Make it Gluten-Free: Use a 1:1 gluten-free flour blend that contains xanthan gum to replicate the structure of regular flour.
