Classic Banana Tray Cake

A light and fluffy banana cake covered in chocolate icing and colourful sprinkles. Tray cakes are ideal for sharing with a crowd at a birthday party, a school shared lunch or for a staff meeting.

There's a lot to love about a tray cake. They are easy to cut up into squares - which is super helpful if you're sharing amongst a group of guests or popping in school lunchboxes. Also, because they are spread out over a larger area, they take less time to cook!

This Classic Banana Tray Cake is a simple yet delicious cake to share with family, friends or colleagues. A great way to use up ripe bananas, this light and fluffy cake is a great treat for both children and adults.

Ingredient notes:

• Bananas: You want your bananas ripe or overripe for mashing. If bananas are too green they will be too starchy and won't mash as well. You can also use frozen bananas. I like to freeze mine, peeled and broken into pieces. Allow them to defrost first. Drain off an excess water, then mash as usual.
• Self raising flour: If you don't have self raising flour to hand, you can replace it with 2 cups of regular flour + 2 teaspoons of baking powder.
• Milk: Regular milk can be swapped out for any plant based milk if you prefer.

Step by step instructions:

Preheat the oven to 180°C fan bake. Line a 22 x 30cm baking tin with baking paper.

Whisk together the butter, sugar, vanilla and eggs in a large bowl. Add mashed banana and milk then stir again. Sift in flour and fold together until just combined.

Pour into the lined baking tin and spread to the edges. Bake for 25 minutes or until cooked through and a skewer inserted comes out clean. Leave to cool.

Icing: Add the softened butter to a large bowl. Sift in the icing sugar and cocoa then pour in boiling water. Whisk together until smooth, adding more water if required. Spread over the cake once it has cooled. Top with sprinkles and serve.

Storage:

Leftover banana cake can be stored in an airtight container in the pantry for up to 4 days.

If you want to get ahead, you could also freeze this banana cake. Once the cake is cooked, allow it to cool completely. Then wrap it in two layers of cling film (this helps to prevents freezer burn) and freeze for up to two months. Allow to defrost completely before icing with your favourite toppings.
