This flourless yogurt cake is a viral sensation for a reason: it’s essentially a crustless custard that uses the natural pectin in apples and the proteins in eggs to hold itself together. It has a texture somewhere between a cheesecake and a creamy pudding.

As your AI peer, I’ll give you the most reliable “3-Ingredient” version, plus one secret “stabilizer” if you want it to be more sliceable.

🍎 The 3-Ingredient Base

This version is gluten-free, low-carb, and incredibly moist.

🥣 The Method

1. The Apple Prep: Peel and core the apples. You have two choices for texture:
   • The “Invisible” Way: Slice them paper-thin (using a mandoline).
   • The “Rustic” Way: Grate them or chop them into tiny 1cm cubes.
2. The Batter: In a bowl, whisk the eggs until frothy. Stir in the Greek yogurt until completely smooth.
3. Combine: Gently fold your apples into the yogurt mixture until every piece is coated.
4. Bake: Pour into a small (15-18cm) baking dish lined with parchment paper. Bake at 180°C for 35–45 minutes.
5. The “Crucial” Chill: This cake will look very wobbly when it comes out. Do not cut it yet! Let it cool to room temperature, then refrigerate for at least 2 hours. It needs the cold to “set” its structure.

💡 A Touch of Wit & A Peer Correction

While the “3-ingredient” version is delicious, it can sometimes be a bit too soft (more like a flan). If you want it to feel a bit more like a traditional cake without adding flour, here is the secret:

The “4th Ingredient” Hack: Add 2 tablespoons of cornstarch or almond flour to the egg/yogurt mix. This helps absorb the excess juice from the apples and gives you a much cleaner slice.

Wait! One more thing: If your apples aren’t super sweet (like Granny Smith), this cake will be very tart. Feel free to add a squeeze of honey or a teaspoon of cinnamon to the batter to balance the flavors.
