Peel the apple and slice into thin wedges. Microwave at 500 W for 3 and 1/2 minutes, then let it cool down.
Mash the banana. I slice it thinly before mashing it.
Put the apple, banana, margarine, egg and pancake mix into a bowl in that order, and mix. Preheat the oven to 180℃.
Pour the batter into a tin lined with parchment paper, and bake for 35-40 minutes at 180℃.
Check on it while it's baking, and cover with foil after around 25-30 minutes.
It's done when a skewer poked through the middle comes out clean. Bake for a little longer if necessary.
Cover it with a moist cloth, and slice it when cooled. It might be tastier if you leave it a day before eating.
Story Behind this Recipe
I wanted to use up some leftover apple and bananas. I didn't want to use a frying pan, so I heated the apple in the microwave. I referred to other pound cake recipes when I was making this. I tried making it with no added sugar so my small children could enjoy it.
Keep an eye on it when baking and adjust the time as necessary. You can melt the margarine with the apple if you like.
