Ingredients

  • 1 1/2 cups sugar
  • 1 cup dairy sour cream
  • 1/2 cup margarine, softened
  • 2 eggs
  • 1 1/2 cups mashed bananas (about 3 large bananas)
  • 2 teaspoons vanilla
  • 3 cups all-purpose flour
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 1/2 cup chopped nuts

Instructions

  1. Preheat oven to 375°F.
  2. Grease and flour a 15 1/2 x 10 1/2 x 1-inch jelly roll pan.
  3. Mix sugar, sour cream, margarine, and eggs in a large mixer bowl on low speed, scraping the bowl occasionally for 1 minute.
  4. Beat in mashed bananas and vanilla on low speed for 30 seconds.
  5. Add flour, salt, and baking soda; stir in chopped nuts.
  6. Spread the batter into the prepared pan.
  7. Bake until brown, about 25 to 30 minutes.

Tips & Substitutions

For a richer flavor, consider using unsalted butter instead of margarine. If you don't have sour cream, Greek yogurt can be a great substitute. To enhance the banana flavor, add a pinch of cinnamon to the batter. Ensure your bananas are very ripe for the best sweetness. If you prefer a nut-free version, simply omit the chopped nuts.

Serving Suggestions

These Sour Cream Banana Bars are delicious on their own but can be served with a dollop of whipped cream or a drizzle of caramel sauce for added indulgence. They pair beautifully with a cup of coffee or tea. For a fun twist, try serving them with a scoop of vanilla ice cream for dessert, or enjoy them alongside a fresh fruit salad for a refreshing contrast.

Storage & Reheating

Store leftover banana bars in an airtight container at room temperature for up to 3 days. If you want to keep them longer, refrigerate for up to a week. To reheat, pop individual bars in the microwave for about 10-15 seconds or warm them in a preheated oven at 350°F for about 5 minutes.

Frequently Asked Questions

Can I use frozen bananas for this recipe?

Yes, frozen bananas work well! Just ensure they are fully thawed and drained of excess liquid before mashing. This will maintain the right consistency of your batter, ensuring your bars are moist and flavorful.

What type of frosting goes best with Sour Cream Banana Bars?

Cream cheese frosting pairs exceptionally well with the flavors of these banana bars. Alternatively, a simple powdered sugar glaze or even a chocolate frosting can complement the sweetness of the bananas beautifully.

Can I make these bars gluten-free?

Absolutely! Substitute all-purpose flour with a gluten-free flour blend. Make sure the blend contains xanthan gum for the best texture. The rest of the ingredients should be gluten-free, but always check labels to be safe.
