📋 Ingredient Notes & Substitutions
Here is what you need to make this easy and moist banana cake with icing recipe:
- Plain flour - is also known as all-purpose flour in the US. I have not tested this recipe using gluten-free flour.
- Baking powder - helps the cake to rise in the oven. Make sure your baking powder has not expired, use my handy guide here to find out how to test it.
- Baking soda - help the cake rise.
- Ground cinnamon - banana cake needs cinnamon! Use ground cinnamon, not cinnamon sticks.
- Salt - use fine sea salt or Kosher salt.
- Unsalted butter - must be soft at room temperature before starting your banana cake.
- Granulated sugar - use either golden/raw or white granulated sugar.
- Brown sugar - use light/regular brown sugar, not dark brown sugar. Measure your sugar by lightly packing it into the measuring cup or use kitchen scales to measure the weight.
- Eggs - must be at room temperature before starting your cake.
- Bananas - very ripe bananas work best, the riper the banana, the better your banana cake!
- Vanilla extract - use either a vanilla bean extract or vanilla essence.
- Milk - whole milk, skim milk, or dairy-free milk. Must be at room temperature.
- Plain Greek yogurt - must be at room temperature to emulsify properly into the batter.
- Extra virgin olive oil - olive oil works best in this banana cake, I don’t recommend using another vegetable oil as it can alter the flavor.
- Icing sugar - is also known as powdered or confectioners sugar.

💭 Tips For Recipe Success
- Use very ripe bananas, the riper the banana, the better the banana cake.
- Make sure your cold ingredients are at room temperature before starting the banana cake. This helps them to emulsify in the batter properly.
- Use parchment paper to line your large baking pan. I like to first grease the pan with the butter then cut to size the parchment paper and stick it to the bottom and sides. This creates smooth and uncreased sides for your cake.
- If you have a non-stick baking pan, I like to grease and flour the pan to achieve smooth sides of the cake after baking.
⏲️ Storage Instructions
- Store in an airtight container, at room temperature for 3-4 days. Then move it to the refrigerator for a further 2-3 days to keep it fresh.
- Freeze this banana sheet cake by allowing it to completely cool after baking. Do not add the icing. Wrap it tightly in plastic wrap and then wrap it again in tin foil. Freeze it for up to 3 months.
- Thaw the cake by removing it from the freezer and transferring it to your refrigerator, still wrapped, for a full 24 hours to slowly thaw. Then sit at room temperature and make the icing.
💬 Recipe FAQ's
Yes! I welcome you to change the icing if you desire. A cream cheese-based frosting, either vanilla or chocolate would be delicious. The choice is yours!
I made this banana cake in a regular-sized rectangle baking pan measuring 7-inch x 11-inch and although it did work, the banana cake raised way above the sides of the pan. It will work, but keep in mind the cake bakes taller than the top of the pan.
Store in an airtight container, at room temperature for 3-4 days. Then move to the refrigerator for a further 2-3 days to keep your moist banana cake fresh.
Yes! Freeze this banana sheet cake by allowing it to completely cool after baking. Do not add the icing. Wrap it tightly in plastic wrap and then wrap it again in tin foil. Freeze it for up to 3 months.
