Have you ever baked a cake that was too dry? The most common cause for a cake lacking in moisture is too much flour or leavening agent was used. Another common cause for a dry cake is too little fat was used. By using sour cream, we are ensuring our cake has a tasty, moist texture.

Banana Cake Ingredients

Since this recipe calls for common ingredients, there’s a good chance you already have everything you need to make it.

And even if you don’t, there aren’t any complicated ingredients to buy. In fact, this is a very affordable recipe to make.

Ingredients List

  • Very Ripe Bananas
  • Sour Cream
  • All-Purpose Flour
  • Granulated Sugar
  • Butter
  • Eggs
  • Baking Powder
  • Baking Soda
  • Vanilla Extract

Bananas: This recipe only needs two bananas to get a great flavor! But the key to any tasty banana cake, is using extra ripe bananas. They are much more flavorful than less ripe bananas so make sure your bananas have a good amount of brown on the skin.

Sour Cream: Sour cream provides fat and also helps bind our other ingredients. The fat content of whole fat sour cream is best, but you can use low fat sour cream in a pinch.

Baking Powder and Baking Soda: These are included because they give our cake height and structure. For the best results, make sure your ingredients aren’t out of date.

Vanilla Extract: This is included as a flavor enhances. Vanilla extract is my preferred option but you can use an alternative such as almond extract if that’s all you have on hand.

Make sure when you cream your butter that you beat it until it’s smooth and creamy. Under creamed butter will lead to a coarse and unappetizing texture.

Frosting Options

This banana cake tastes great with all different types of frosting. I often use chocolate or vanilla, but butterscotch and even a creamy banana frosting works great!

While you can use a premade frosting for your banana cake, homemade tastes so much better and doesn’t take long to make at all.

I like to prepare my frosting while my cake is cooling. This will allow you to frost your cake as soon as it has finished cooling so you can enjoy your cake without delay!

Here are some of my favorite frosting for banana cake, but you can go to the top of the page and search for more. I have a lot of great frosting recipes on Treat Dreams.

Easy to Follow Instructions

If you’re one of those bakers who thinks “from scratch” means a recipe must be difficult, have no fear! This banana cake is super easy to prepare and it has a quick bake time.

In just a few easy steps, you will have your cake in the oven. A couple important reminders though, make sure you use extra ripe bananas and cream your butter until it is smooth and creamy.

Want to cool your cake like a pro? Once out of the oven, place cake (in pan) on a wire rack for five minutes. Then gently loosen the sides with a rubber spatula and turn your pan upside down and gently rest cake on cooling rack. Finish cooling and then frost!

Cake Tip

Step 1: Preheat your oven and mash your bananas.

Step 2: Cream butter and sugar.

Step 3: Beat in one egg at a time.

Step 4: Combine all your dry ingredients and add them, and your sour cream, to your butter mixture.

Step 5: Mix in your vanilla extract then fold in your mashed bananas.

Step 6: Pour cake batter into your greased cake pans.

Step 7: Bake for 25-30 minutes.

Step 8: Cool cake completely then frost.

Ever had a homemade cake fall and lose it’s height? There are a few common causes for this. You either used too much leavening agent, too much sugar or liquid was used, or you didn’t bake it long enough. Make sure you follow your recipe and you’re cake should have plenty of height.
