The banana and cinnamon flavors are absolutely divine paired with this easy vegan frosting (which can be whipped up in under 5 minutes). But you could also top it with non-dairy cream cheese frosting.
📖 Recipe Overview
- Moist, fFuffy, and Tender. Thanks to a combination of ripe bananas, non-dairy yogurt, and homemade buttermilk, the texture of this banana tray cake is perfection.
- Easy to Make. Straight-forward and simple to put together with pantry staple ingredients. You don't need to be a skilled cake decorated either. Similar to this chai sheet cake, the frosting is best just slapped on with a spoon or spatula, no need to make it perfect!
- Great for Reducing Food Waste. I often have spotty bananas lying on the kitchen counter. This, along with banana muffins, is one of my favorite ways to use them up and prevent them from going to waste.
📝 Ingredients Needed
Here's everything you need to make this easy vegan banana cake recipe from scratch:
- Spotty bananas. Slightly overripe bananas made the best banana cake. Underripe bananas are too starchy and lack the sweetest, and flavor needed for this cake.
- Vegan buttermilk adds rise to the cake, giving it a beautiful fluffy crumb.
- Vegan yogurt. I love adding the to vegan cake recipes such as apple cake, and vanilla cupcakes. It acts as an egg replacer in vegan baking, I prefer using it to applesauce a lot of the time as it avoids adding additional sweetness.
- Soft brown sugar and granulated or cane sugar. A combination of sugars works best, as brown sugar adds moisture and a caramelized flavor whilst white sugar provides structure.
- Ground cinnamon adds a little warming spice to the cake. You can skip it if you aren't a fan, or even sprinkle extra on top of the frosting if you love it!

(2) Cream together the vegan butter, granulated and brown sugar until light and fluffy.
(3) Whisk in the vegan yogurt and vanilla, followed by the mashed banana.
(4) Alternate between mixing in the vegan buttermilk and dry ingredients (plain flour, cinnamon, baking powder, and sea salt) in 2 increments until just combined.
How to assemble and bake the banana cake:
(5) Pour the cake batter into a prepared rectangular pan, and smooth out the top with an offset spatula.
(6) Bake until golden brown, this will be between 35-40 minutes, depending on your oven.
(7) Prepare half a batch of vegan frosting and use a spatula or large spoon to swirl it on top of the cooled cake.
(8) Garnish the cake with fresh banana slices or dried banana coins, just before serving.
Absolutely, you can divide the batter into 2x 6", 7", or 8" pans lined with parchment paper.
Note that thinner cakes will take a little less time to bake, so check them at 25-30 minutes.
This banana cake is best served at room temperature to ensure it keeps its fluffy consistency.
If you don't plan on eating it on the day it's baked, seal it in an airtight container and refrigerate for up to 5 days. Then remove the cake from the fridge about 1-2 hours before serving to bring it back to room temperature.
Yes, you can freeze it either frosted or unfrosted. For unfrosted cakes, carefully wrap them in parchment paper and freeze. Frosted cakes may be better off in an airtight container to avoid squashing the buttercream.
To defrost, leave the cake in the refrigerator overnight before serving.
