FAQ

Can I use different fruits instead of bananas?

Yes, try pineapple rings, peach slices, or apple wedges. Adjust sugar if using tart fruits and consider cooking time differences.

What if my cake sticks to the pan when inverting?

Run a knife around edges before inverting and ensure proper greasing. If stuck, place a warm damp towel over the pan briefly.

How long will this cake keep fresh?

Store covered at room temperature for 3 days or refrigerate up to 1 week. The fruit topping stays moist longer when refrigerated.
