How to Make (Step-by-Step Instructions)

Step 1: Prepare the Oven and Pan

Preheat your oven to 175°C (350°F). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.

Step 2: Cream Butter and Sugar

In a large bowl, beat the softened butter and sugar until light and fluffy. This step helps create a soft texture.

Step 3: Add Wet Ingredients

Mix in eggs one at a time, then add mashed bananas and vanilla extract. Stir until smooth and well combined.

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together flour, baking soda, and salt. Gradually add this mixture to the wet ingredients.

Step 5: Add Sour Cream

Fold in sour cream or yogurt. This adds moisture and keeps the bars soft and tender.

Step 6: Bake and Cool

Spread the batter evenly in the pan and bake for 22–25 minutes, or until a toothpick comes out clean. Let cool completely before frosting.

  • Use room temperature ingredients – helps everything blend smoothly

These small details ensure consistent, bakery-style results.

Banana bars are easy to customize based on your taste:

Cream Cheese Frosting

Swap the frosting for cream cheese frosting for a richer, tangier finish.

Chocolate Chip Banana Bars

Add ½ cup chocolate chips to the batter for extra indulgence.
