What I said about this banana poppy seed cake in 2013:

I don’t bake many cakes, layer or otherwise, because I find them too tempting to have in the house if there’s not a lot of other people to share them with, or a big reason to celebrate.

When my kids were little I always baked and decorated their birthday cakes. However, I hardly ever made them from scratch, or for reasons other than a birthday celebration.

Back in the day, Betty Crocker and Duncan Heinz were two of my closest friends!

How this recipe came to be:

I made this cake to celebrate two wedding anniversaries. Mine and my husband’s and our very best friends. The results were very tasty indeed.

I remembered from years ago that our friends both used to enjoy the Sara Lee banana cake that could be purchased in the freezer case at the grocery store.  

I wanted to try and mimic what I remember that cake tasted like, and I think I hit the nail pretty squarely on the head with this banana poppy seed cake with banana buttercream frosting.

The inspiration for this recipe:

The recipe I started with, for both the cake and the frosting, came from the cookbook “At My Grandmother’s Table” by Faye Porter.  

I adapted the recipe only slightly.

How to store banana poppy seed cake:

Store this cake in an air-tight cake container in the refrigerator for up to 4 days.

Can this cake be frozen?

I don’t recommend freezing the completed cake after it’s been frosted, but if you’d like to make and bake the cake rounds, wrap them well (individually, and once completely cooled) in plastic wrap.

Freeze the cake for up to 3 months.

When you’re ready to make and assemble the cake, make the banana buttercream, and frost the thawed cake as the recipe suggests.

How to slice a cake for an even layer cake:

Serving suggestions:

Allow the banana cake to sit at room temperature for 30 minutes before serving.

How to properly cut and serve a layer cake:

 

How to make banana buttercream frosting:

  • In a large bowl with a hand mixer, or in the bowl of a stand mixer, cream together the butter, overripe bananas, confectioners sugar, and pure vanilla extract until smooth and creamy.

Can the nuts be omitted from this recipe?

Yes. By all means, if you aren’t a fan of nuts you can certainly leave them off.

However, if you’d like to switch the type of nut called for in this recipe, then you’re more than welcome to use whatever nut happens to be your favorite.

Chopped pecans, walnuts, cashews, or even honey-roasted peanuts come to mind as good options.

Yield: 16 slices

Banana Poppy Seed Cake with Banana Buttercream Frosting

An entire banana poppy seed cake covered in pecans on a glass cake plate.
Prep Time 15 minutes
Cook Time 30 minutes
Additional Time 1 hour
Total Time 1 hour 45 minutes

Ingredients

  • 1½ cups granulated sugar
  • 2 cups all-purpose flour
  • 2½ teaspoons baking powder
  • 1 teaspoon salt
  • 4 large overripe bananas, peeled
  • 1 teaspoon pure vanilla extract
  • 2 large eggs
  • 2 teaspoons poppy seeds
  • 8 tablespoons butter, melted
  • FOR THE BANANA BUTTERCREAM FROSTING:
  • 2-3 overripe bananas, peeled
  • 8 tablespoons butter, softened
  • 5 cups confectioners sugar
  • 1 teaspoon pure vanilla extract
  • 1½ cups chopped macadamia nuts (optional, or other chopped nuts)

Instructions

    1. Preheat oven to 350 degrees.
    2. TO MAKE THE CAKE:
    3. In a large bowl combine all of the ingredients for the cake (except the butter) and blend well until combined.
    4. Pour in the melted butter and stir well to combine.
    5. Pour the batter evenly into the two prepared cake pans that have been sprayed liberally with baking spray.
    6. Bake for approximately 30-35 minutes, or until a toothpick inserted in the middle of each cake comes out clean.
    7. Cool the cakes for 15 minutes and then turn them out onto cooling racks to cool completely. (Once cooked, if needed, use a serrated knife to level off any uneven cake surfaces).
    8. Before frosting freeze the cakes for 20 minutes.
    9. TO MAKE THE FROSTING:
    10. Place all the frosting ingredients in a large bowl and blend at very low speed.
    11. Once the ingredients come together, turn the speed to high and blend until the frosting becomes a smooth and spreadable consistency.
    12. Once cooled, remove the cakes from the freezer and place one of the cake discs on a platter or cake stand of your choice.
    13. Using an offset spatula (or large butter knife) place approximately 1 cup of the frosting on the top of the cake layer and spread the frosting evenly around the cake top.
    14. Place the second cake round directly on top of the iced round and frost that layer with approximately 2/3 cup of the frosting.
    15. When frosting the sides of the cake, an offset spatula works best when placing a thin layer of icing around the sides of the cake.
    16. Note ~ This first layer of thin frosting is the "crumb coat" and it will prevent crumbs from coming off the cake and mixing in with your beautiful frosting. Make sure when icing your cake with the crumb coat that you work the frosting in only one direction. This will additionally help the cake stay intact without crumbs forming in the frosting.
    17. Place the crumb-coated cake in the fridge for approximately 30 minutes to set.
    18. You can now slather frosting liberally on the top and sides of your crumb coated cake.
    19. Once the cake is completely iced place some of the chopped macadamia nuts in your cupped fingertips and gently press the nuts onto the iced sides.
    20. Continue placing the nuts around the entire cake and refrigerate until 30 minutes before serving.
    21. Allow the cake to sit at room temperature for 30 minutes before serving.
    22. Enjoy!

Notes

Note ~ Any leftover frosting can be saved and used for cupcakes or cinnamon rolls. YUM!

Your "baby steps" into homemade cake baking are pretty steady Renee. This looks moist and delicious and I'm sure it was a big hit with your best friends. What a nice thing to have done for their anniversary. I bet they didn't have to be asked twice if they wanted to take any leftovers home with them ;)
