Recipe: Banana Cake Squares

banana cake squares

Whether you want a square of cake (or three) with a cuppa or you want to bake something to share when you have friends over, why not try this banana cake squares recipe? You might be over banana themed bakes after the whole banana bread hype of three years ago, but if you’re not…

This recipe was was originally shared on my blog in May 2018.

I decided to mix all the ingredients for the cake mixture together in the same bowl when I baked these, rather than measure them all out separately. I reset the scales to 0 for each measurable ingredient I added.

Makes: 30 cake squares


100g salted butter
95g caster sugar
100g self raising flour (plus some extra)
2 free-range eggs
semi-skimmed milk
1 banana
icing sugar


Preheat your oven to 190

→ Mix together the butter and sugar, then add the 2 eggs. Use an electric whisk to mix it all together.

→ Add 100g of self-raising flour to the mixture and stir it in with a spoon.

→ Add a small amount of semi-skimmed milk and stir it again.

→ Liquidise the banana and add it to the mixture. Stir it in with a bit of extra flour.

Now it’s time to put your cake mixture in the oven.

greasing the baking trays

→ Grease a baking tray (I used butter and flour for this) and spread the cake mixture out across the tray.

→ Bake for 18-20 minutes (or until it’s cooked properly – I always use a skewer to check cakes are cooked thoroughly).

→ Once your banana cake has finished baking, let it cool then add some icing sugar on top of the cake using a small sieve. This can be easier said than done, I had to re-route some with a flat knife where it had gone on a bit thick in places.
