Best Ever Moist Banana Buttermilk Cake with Cream Cheese Frosting

Best Ever Moist Banana Buttermilk Cake with Cream Cheese Frosting

Best Ever Moist Banana Buttermilk Cake with Cream Cheese Frosting has mega banana flavor, light, moist, and cakey from creaming the butter and sugars. The use of  100% refined coconut oil, sour cream and cream cheese frosting makes this moistest cake ridiculously rich and decadent. The cake is enriched with flavors from the ripe bananas, vanilla and cinnamon.The recipe starts with 3 mashed bananas. The bananas should be ripe and spotty. More brown spot means sweeter, more banana flavor in the cake. You can beat the bananas at high speed in an electric mixture but I prefer to mash the bananas by hand, using a fork.

The use of buttermilk is essential to attain the perfect moistness in the cake. For this recipe, you’ll need 1 cups of buttermilk. Instead of running to the stores every time I need buttermilk, here’s what I do:  measure 1 Tablespoon of fresh lemon juice or white vinegar, then add it to 1 cup milk. Stir it around, let it sit for 10 minutes undisturbed, then pour into the batter.  To keep the cake extra rich, I add half a cup of sour cream, another perfect moist-maker ingredient.

The perfect cream cheese frosting, when spread on top of the cake, sinks into it, making it even more moist.

The trick to getting a perfectly baked, moist banana cake is slow cooking. If the temperature of the oven is too high, then the top of the cake cooks fast while the inside is still cooking. Hence it cracks. To prevent top cracking in the cake, avoid opening the oven door early in baking. Also the oven temperature should not be too high. Generally the optimal oven temperature for cooking cakes is 350 degrees F.

To evenly bake cakes in 2 pans, bake them in the same level rack . Also, it is preferable to bake cakes in the middle rack of the oven.

  6. Divide and pour batter into the two prepared pans and bake in preheated oven for 45-55 min or until toothpick inserted in center comes out clean.

  8. For the frosting, cream the butter and cream cheese until smooth, using electric mixer or by hand. Beat in vanilla extract. Add icing sugar and beat on low speed until combined, then on high speed until frosting is smooth.(I did the frosting mixture by hand in a bowl).
  9. Fill and spread the frosting on cooled cake, covering the sides and the top of the cake.
  10. For topping, sprinkle coconut powder or chopped toasted walnuts over top of the frosting, as desired. Drizzle chocolate ganache along the edges of the cake on the top so that it falls in zig zag pattern along the sides.
