Banana Cake Slice with Marshmallow Frosting **Not Gluten Free**

Enough pictures, it’s time for some words now.  Words like delicious, mouthwatering, fluffy, delightful and dreamy.

This cake is amazing, truly amazing, but I can’t believe (and I’m kind of kicking myself about this) that I didn’t put chocolate chips in it.  It would have been like a cake version of a campfire banana split!

So, have I intrigued you yet?  Do you want to make your own Banana Cake Slice with Marshmallow Frosting?  Want the recipe now?  Okay.

I found the recipe at It calls for cream cheese frosting, which I think would be equally amazing, but I just couldn’t go past marshmallow frosting.

Banana Cake Slice with Marshmallow Frosting


125g butter, softened
300g caster sugar
2 eggs
250ml sour cream
1tsp vanilla essence
250g plain flour
1 tsp bicarb soda
1/4 tsp salt
225g ripe banana, mashed

Making the cake/slice

First you want to pre-heat your oven to 180 degrees C.  Then, in a large bowl cream together the butter and sugar.  Once smooth, beat in one egg at a time, then stir in the sour cream and vanilla.  Sift in the flour, bi-carb and salt, stir to combine.  And last but not least, stir in the banana.  Pour it into a pre-lined lamington pan or something of a similar size, and bake for 20-25 minutes, longer if necessary.  For me it was.  Let it cool completely before icing.

Making the Marshmallow Frosting

The recipe for the frosting comes from Martha  I halved the recipe, and it was still slightly too much, but I LOVE the marshmallow frosting so much, that a little bit extra is fine with me.


4 large egg whites
1 cup of sugar
1/4 tsp cream of tartar
1 tsp vanilla extract

Making the Frosting

Put the eggs, sugar and cream of tartar in a heatproof bowl over a saucepan of simmering water.  Whisk continually until the sugar has dissolved and the egg whites are warm to touch.
Transfer the eggs into an electric mixer bowl, add vanilla, and whisk again until stiff glossy peaks form.  Use as soon as it’s ready.

P.S. The frosting tastes really nice just with a spoon too.
