Learn how to cook Banana Split Sheet Cake by making a moist banana cake batter, baking it in a 13×9-inch pan, then topping the cooled cake with vanilla frosting, chocolate ganache, and traditional banana split toppings. The simple method creates a perfect party dessert that captures all the flavours of the classic ice cream treat.
Yes! If you don't have buttermilk, make a quick substitute by mixing 120ml of regular milk with 1 tablespoon of lemon juice or white vinegar. Let it sit for 5 minutes until slightly thickened. This homemade "buttermilk" will provide the same moisture and tenderness to your cake.
For the most flavourful cake, use very ripe bananas with dark brown or black peels. These overripe bananas are softer, sweeter, and have a more concentrated banana flavour that will shine through in your cake. If your bananas aren't ripe enough, try baking them in their peels at 150°C for 15-20 minutes.
Absolutely! The unfrosted cake freezes beautifully for up to 3 months when wrapped tightly in cling film and foil. For frosted cake, freeze individual slices on a baking sheet until solid, then wrap. Thaw overnight in the refrigerator and add fresh toppings just before serving.
