Is air fryer cake good?
Heck yeah! This cake was super light and fluffy and MOIST!
How long do you bake a cake in an air fryer?
It depends on the size of your pan – I used 7″ pans and they were done in 20 minutes. Keep in mind – a small basket air fryer – where maybe you can only fit one 6″ cake pan – is going to cook the cake more quickly – than a larger oven style. Always check your cake early – you can always add more time!
Can you use regular cake pans in an air fryer?
Yes – metal or silicone both work in an air fryer!
What’s the difference between Banana Cake and Banana Bread?
The cake is definitely lighter and more moist. It’s got buttermilk and more sugar – which add to that difference in texture.
Can banana cake be frozen?
Yes! I actually suggest freezing the cake once you take it out of the oven for a little while so you can frost it.
What kind of icing do you use on banana cake?
I think a cream cheese frosting works great!
