Sour Cream Alternative

I know some people might be turned off by sour cream.  So, as a replacement, you can always use plain Greek yogurt instead. As a note, just make sure it’s not flavored with vanilla, if you want the slightly tangy factor, like sour cream.

Cream Cheese Frosting Alternatives

I’m partial to cream cheese frosting especially with these bars…sooo good and tasty together, but these would be really good with a brown butter frosting as well.

  • As for the frosting, you can frost these with store-bought prepared cream cheese frosting if you want, or buy another other flavor for that matter.
  • You could also dust these banana lovelies with some powdered sugar if you want to cut down calories.

Storing Banana Bars

Store frosted bars for 4-5 days in an airtight container with the cream cheese frosting in the fridge since we they have cream cheese frosting. Can also be stored in the fridge or freezer.

If freezing, just thaw at room temperature or in the fridge.  Make sure to keep the bars covered in plastic wrap or an airtight container when thawing and place back in fridge if thawing at room temperature.

  1. So very very delicious!!! I made these last night to bring to my family’s Thanksgiving Day feast today… One thing I did switch up though is instead of regular confectioner’s sugar for the frosting I opted to use a Keto-friendly alternative! I used Swerve instead! It came out really really good! Just an idea though for anyone wanting to cut out some carbs and sugar but still wanting the taste!

  2. These sound so yummy, Kim!! Love banana cake so I know I’d really enjoy these. The sour cream sounds so good and probably make them so moist, too. Such a great combo.. And don’t get me started with that frosting! 😀

  3. Sometimes the traditional, classic recipes are the best, aren’t they? I love banana and what a great idea combining them with sour cream in these tasty bars. Add a cream cheese frosting and I pretty much know I’ll eat the whole pan! haha! These sound so delish!

  4. Oh, these bars will make a great after school snack. Now that school is reopening next week, my kids will be totally thrilled to dig into this. Now, I just have to wait for my bananas to ripe.

  5. I totally love baked banana treats! Especially if there’s a cream cheese frosting! This recipe looks simple and amazing! I keep all my overripe bananas in the freeze for such an occasion, so thanks for the recipe! I’m Pinning!

  6. Oh yes; this is what I like, not too sweet; moist and refreshing ! Is it hot at your place ? We are getting crazy over here 🙂 Bye dear !
