I enjoyed obsessed over it at a family reunion the other weekend. My cousin made it and I stalked her down like a dessert creep and proceeded to talk her ear off about cream cheese frosting and spotty bananas for 35 minutes straight. What? You don’t do that at parties? It was the moistest cake I’ve ever eaten. Stick-to-the-back of your fork moist. The perfect cream cheese frosting, both sweet and tangy, sinking into the top of the cake made it even moister. Sweet, but not overpowering. Mega banana flavor, certainly more banana flavor than any banana bread I’ve ever eaten. Very buttery and cakey from creaming the butter and sugars. Just a ridiculously rich, decadent dessert. The banana cake was dense, but not heavy. If that makes any sense? (Coming from the lady who talks about rotting bananas at social gatherings, but stick with me here.) The crumb was very soft, but they were tight crumbs. The cake didn’t fall apart when you took a forkful. She told me this cake comes out perfect every time she makes it. And such perfection is reinforced, she told me, when absolutely everyone who has a slice begs her for the recipe. It is, hands down, the best banana cake I’ve ever had. And I haven’t stopped thinking about it since.
How to Make Banana Cake
The recipe starts with 1 and 1/2 cups (345g) mashed bananas, or about 4 medium or 3 large ripe bananas (above). Now, make sure those bananas are nice and spotty. The bananas you see above are just right (and it’s what you want for banana bread, chocolate banana bread, and banana muffins, too). More brown spots = sweeter, more banana flavor. Your cake will thank you. I simply mash the bananas in my mixer—the same mixer I use for creaming the butter and sugars. Beat the bananas on high speed for a minute, then transfer to another bowl. I don’t even wash the mixing bowl—just throw the butter right in and start creaming!
Can I Use Frozen Bananas?
Yes and I do this often. Thaw the frozen bananas at room temperature. Drain off any excess liquid, mash, then use as instructed in the recipe below. See How to Freeze & Thaw Bananas for Baking. Here’s the batter. There will be some lumps. One more thing to note: buttermilk. As you guessed, buttermilk is the moist-maker in this cake. The cake wouldn’t be what it is without it! You also need the acid in buttermilk to help the baking soda do its job. I rarely have buttermilk in my refrigerator, so I always sour whole milk instead. For this recipe, you need 1 and 1/2 cups of buttermilk. If you don’t keep buttermilk on hand either, you can make this buttermilk substitute: measure 1 Tablespoon of fresh lemon juice or white vinegar. Pour into a liquid measuring cup. Then add enough whole milk until it reaches 1 and 1/2 cups. Stir together, let it sit for 5 minutes, then use in the recipe. To keep the cake extra rich, I recommend whole milk when you are souring milk. Is this not the silkiest and smoothest cream cheese frosting you’ve ever seen? Well, it’s the silkiest and smoothest cream cheese frosting I’ve ever tasted! It’s pretty similar to our cream cheese frosting that we use for carrot cake, but there’s a little less cream cheese for the amount of butter. So, this makes the frosting a little more silky. And definitely more buttery! There’s also a lot of cream cheese frosting. When you begin slathering it onto the cake, you’ll probably go “Sally, this is way too much frosting!” But it’s not. You want a nice thick layer. It’s essential. If you love baking with brown butter, the brown butter cream cheese frosting from my zucchini cake would be fantastic here. If you are not into cream cheese frosting or just want to try something different, try it with traditional vanilla buttercream, this salted caramel frosting, or even white chocolate buttercream frosting instead. All are seriously delicious combinations! The best banana cake I’ve ever had. We love it so much we turned it into a chocolate marble banana Bundt cake, too. And if you can’t get enough sheet cakes, you’ll want to try this fresh apple cake next!
