Step‑by‑Step Instructions for Sour Cream Banana Bars

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, grab a 10×15 jelly roll pan and generously grease it with butter or non-stick spray. This will ensure your Sour Cream Banana Bars don’t stick, allowing for easy removal once they’re baked.

Step 2: Mix the Base Ingredients
In a large mixing bowl, combine sugar, sour cream, softened butter, and eggs. Using an electric mixer, mix on low speed until the ingredients are well incorporated, which should take about 1 to 2 minutes. You’ll want a smooth mixture without any visible lumps for the best texture in your Sour Cream Banana Bars.

Step 3: Add Bananas and Vanilla
Next, peel and mash about three ripe bananas in a separate bowl until smooth. Add these mashed bananas along with pure vanilla extract into the mixing bowl. Blend on low speed for an additional 30 seconds until everything is combined seamlessly. The banana flavor will be the star of your bars, imparting moisture and sweetness.

Step 4: Incorporate Dry Ingredients
Now, it’s time to combine the dry ingredients. Sift in the all-purpose flour, baking soda, and salt into the banana mixture. Using medium speed, mix until just combined, about 1 minute. Avoid overmixing to keep the bars tender, as overmixing can lead to a denser texture in your Sour Cream Banana Bars.

Step 5: Bake the Bars
Pour the luscious batter into your prepared jelly roll pan, spreading it evenly with a spatula. Place it in the preheated oven and bake for 18-22 minutes. You’ll know they are done when the top is golden brown and a toothpick inserted into the center comes out clean. The aroma will fill your kitchen with warmth and anticipation!

Step 6: Cool the Bars
Once baked, remove the pan from the oven and set it on a wire rack to cool for about 10-15 minutes. Allowing the bars to cool slightly will ensure that the frosting sticks beautifully when added later, giving you that perfect finish for your Sour Cream Banana Bars.

Step 7: Prepare the Browned Butter Frosting
In a small saucepan, melt half a cup of butter over medium heat, stirring frequently until it turns golden brown with a nutty aroma. This should take about 5-7 minutes. Once browned, remove it from heat and let it cool for a few minutes. The frosted tops will elevate your Sour Cream Banana Bars to heavenly indulgence.

Step 8: Mix the Frosting
In a mixing bowl, whisk together the cooled browned butter, powdered sugar, and half-and-half until smooth and velvety. If the frosting is too thick, you can add a dash more half-and-half to reach your desired consistency. This luscious, creamy frosting is what makes your Sour Cream Banana Bars truly irresistible.

Step 9: Frost and Serve
Finally, spread the browned butter frosting evenly over the cooled banana bars using a spatula. Allow the frosting to set for a few moments before cutting the bars into desired squares or rectangles. Ready to serve, these Sour Cream Banana Bars are perfect warm or at room temperature, and they will surely be a hit!

Tips for the Best Sour Cream Banana Bars

• Don’t Overmix: Mixing the batter too much after adding flour can lead to dense bars. Stir just until combined for a tender texture.

• Perfectly Ripe Bananas: Use bananas that are very ripe; their natural sweetness enhances flavor and ensures moisture in the Sour Cream Banana Bars.

• Brown Butter Carefully: When browning the butter for frosting, watch closely for a golden-brown color and nutty aroma. Burnt butter can ruin the frosting!

• Room Temperature Ingredients: Ensure that your butter and sour cream are at room temperature. This helps them blend better and creates a smoother batter.

• Cool Before Frosting: Allow the bars to cool completely before frosting to ensure a smooth application. Frosting on warm bars can melt and slide off.

Make Ahead Options

These Sour Cream Banana Bars are ideal for busy home cooks looking to meal prep! You can prepare the batter up to 24 hours in advance; simply mix all the ingredients and store it in the refrigerator. For the best results, cover the bowl tightly with plastic wrap to maintain moisture and prevent browning. You can also bake the bars and let them cool, then frost them and serve up to 3 days later; just keep them in an airtight container to keep them fresh. When you’re ready to serve, simply cut and enjoy that irresistibly moist treat! Preparing ahead saves time and gives you more moments to spend with your loved ones.
