Sour Cream Banana Bars Ingredients

For the Bars

All-purpose flour – Provides structure; can substitute with gluten-free flour for a gluten-free version.
Baking soda – Acts as a leavening agent, helping the bars rise beautifully.
Salt – Enhances flavor, balancing the sweetness of the bananas.
Unsalted butter – Adds richness and moistness; use salted butter for a different flavor profile.
Granulated sugar – Sweetens the bars; brown sugar can deepen the flavor profile.
Large eggs – Binds ingredients together, contributing to moisture; flax eggs work for a vegan alternative.
Sour cream – Keeps the bars moist and adds tanginess; plain Greek yogurt can be used as a replacement.
Vanilla extract – Infuses the batter with warm, inviting flavor.
Ripe bananas – The star ingredient; they provide natural sweetness and moisture; use 2 or 3 based on your banana preferences.

For the Cream Cheese Frosting

Cream cheese – Offers a rich, creamy texture that perfectly complements the bars.
Powdered sugar – Sweetens and thickens the frosting for that perfect spreadable consistency.

How to Make Sour Cream Banana Bars

Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking pan or line it with parchment paper for easy removal of the bars.
Whisk together the flour, baking soda, and salt in a medium bowl. This ensures all dry ingredients are evenly mixed for a uniform texture in your bars.
Cream the softened butter and granulated sugar in a separate bowl until light and fluffy, about 2-3 minutes. This will help incorporate air and create a tender crumb.
Beat in the eggs one at a time, mixing well after each addition, then add the sour cream and vanilla extract. The mixture should be well combined and smooth before moving on.
Combine the dry ingredients gradually into the wet mixture. Mix until just incorporated, then fold in the mashed bananas gently, avoiding over-mixing for a lighter texture.
Pour the batter into the prepared baking pan and spread it evenly. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
Cool the bars completely in the pan on a wire rack before frosting. This prevents the cream cheese frosting from melting and ensures a beautiful finish.
Frost the cooled bars by beating cream cheese and butter together until smooth. Gradually add powdered sugar, mixing until creamy, and then spread evenly atop the bars.

Optional: Top with chopped nuts for added crunch and flavor contrast.

Sour Cream Banana Bars Recipe FAQs

How do I choose the right bananas for this recipe?
Absolutely! For the best flavor and moisture in your Sour Cream Banana Bars, look for bananas with plenty of brown spots. The riper the banana, the sweeter it will be. Aim for fruit that is soft but not overly mushy; this indicates it's ready for baking!

How should I store my Sour Cream Banana Bars?
Very! To keep your delicious bars at their best, store them in an airtight container at room temperature for up to 3 days. If you want to keep them fresh longer, you can refrigerate them for a week. Just be sure to bring them back to room temperature before serving for the best taste.

Can I freeze Sour Cream Banana Bars?
Of course! To freeze your Sour Cream Banana Bars, first, let them cool completely. Then, cut them into individual pieces (if preferred) and wrap each piece in plastic wrap or place them in a freezer-safe bag. They’ll keep well for up to 2 months. When you’re ready to enjoy them, simply thaw them overnight in the fridge!

What if my banana bars come out too dense?
No worries! If your bars turn out dense, it often means they were over-mixed. To avoid this in the future, mix the dry ingredients into the wet mixture slowly and stop mixing just as everything is combined. If you notice dark spots on the bars after baking, it could indicate over-baking as well. Aim for a toothpick that comes out clean but not too dry when testing for doneness.

Are Sour Cream Banana Bars suitable for dietary restrictions?
Absolutely! If you have dietary restrictions, you can adapt this recipe easily. Substitute the sour cream with plain Greek yogurt for a lighter option. For a gluten-free version, simply use a gluten-free flour blend. If you require vegan options, try using flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water for each egg) in place of eggs. Just remember that texture and taste might vary slightly with substitutions.

How long do Sour Cream Banana Bars last?
These bars are best enjoyed within a week when stored in the refrigerator. However, for optimal freshness, eat them within the first 3 days when kept at room temperature. If frozen, they maintain great flavor for up to 2 months; just be sure to thaw them before serving!
