This banana cake recipe is flavored with cinnamon, nutmeg, and allspice. While most banana cakes are topped with cream cheese frosting, this two-layer cake is frosted with a banana buttercream frosting, giving it a delightfully strong banana flavor.

For best results, use very ripe bananas. They add more flavor and sweetness than unripe bananas. They're also easier to mash. If you end up with too many bananas and no time for baking, simply freeze ripe bananas for later. Defrosted, they will work perfectly in this cake.

This fruity, moist cake is a nice alternative to chocolate or vanilla. Make it for your next potluck, gathering, or family dinner.

Tips

  • To toast nuts, spread out in a single layer on a baking sheet. Toast in a 350 F oven, stirring occasionally, for 10 to 15 minutes. Alternatively, toast in an ungreased skillet over medium heat, stirring, until golden brown and aromatic.
  • Make your own confectioners sugar easily and quickly with just granulated sugar. This way, you only make as much as you need, saving money.

Recipe Variations

  • Change up the frosting if you'd like, and use buttercream or chocolate frosting. We're partial to the banana frosting ourselves though.
  • Instead of toasted pecans, feel free to use walnuts in their place.
