3️⃣ Add Apples

• Peel apples (optional but recommended).

• Slice very thinly.

• Fold slices gently into batter until fully coated.

The batter will look heavy on apples — that’s correct.

2. Sprinkle with brown sugar, cinnamon, and nuts.

3. Drizzle melted butter on top (optional).

4. Bake 40–50 minutes until golden and center is set but slightly soft.

5️⃣ Cool

Let cool at least 30 minutes before slicing.
It firms up more as it cools.

🍰 Texture

• Inside: soft, custardy, almost cheesecake-like

• Top: slightly caramelized and nutty

• Not fluffy like regular cake — more dense and creamy

💡 Tips

• Use sweet apples (Honeycrisp, Fuji, Gala).

• Chill before serving for cleaner slices.

• Dust with powdered sugar before serving.

• Serve with whipped cream or vanilla ice cream.
