This Banana Poppy Seed Cake with Vanilla Bean Frosting is a moist one bowl banana snack cake that pleases everybody, from the pretty crunch of the poppy seeds to the creamy vanilla buttercream, it’s a joy to make, and eat!
That handful of everyday ingredients pulls together to make a really special cake…I’m not sure if it’s the extra ripe bananas, the poppy seeds, the sour cream in the batter, or that frosting with a virtual galaxy of vanilla bean specs. But in the end, does it really matter? This cake is perfect, that’s all we need to care about, right?
Vanilla beans are expensive, but you can also use vanilla bean paste, which is one of my favorite new discoveries. It gives you that same flavor and beautiful specs at a much lower cost. The heavy vanilla presence in this frosting really makes a difference, and extract just doesn’t cut it.
Of course you could double the recipe and made a grand layer cake, but I like it this way, it’s more approachable, more snackable. And I could never eat a layer cake for breakfast 😉
I know this is going to become your favorite…

Banana Poppy Seed Cake with Vanilla Bean Frosting
the vanilla bean frosting
- 3 to 4 ounces of cream cheese, at room temperature (about half the 8 oz package)
- 2 Tbsp unsalted butter, at room temperature
- the seeds from 1 vanilla bean
- 2 cups confectioner's sugar, sifted
- milk or cream for thinning the icing
- a squeeze of fresh lemon juice
- Set oven to 350F
- Cream the butter, sugar and sour cream together. Beat in the egg, bananas and vanilla. (Make sure the bananas are completely mashed smooth first)
- Sift the flour, salt and baking soda into the wet mixture. Mix together just until thoroughly combined. Fold in the poppy seeds.
- Spread the batter into a greased 8x8 square baking pan. I lined mine parchment paper (or foil) so I could remove it easily for a neater presentation and cutting.
- Bake for about 25 minutes until a toothpick just comes out clean.
- Cool before frosting.
- To make the frosting--- mix everything together until you have a thick, creamy, spreadable consistency. Taste to adjust your lemon juice.
- Heap onto the completely cooled banana cake and swirl it around thickly.
