Step 1: Preheat & Prep

Preheat your oven to 375°F (190°C).
Grease and flour a 9×13-inch baking pan, or line it with parchment paper.

Step 2: Make the Batter

In a large mixing bowl, cream together the sugar, sour cream, and butter until smooth.
Add the eggs, vanilla, and mashed bananas. Mix until well combined.

Dairy & Eggs

In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon (if using).
Gradually add the dry ingredients to the wet mixture, stirring until fully incorporated.

Fold in nuts, if using.

Step 3: Bake

Pour the batter into the prepared pan and spread evenly.
Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
Let cool completely before frosting.

Step 4: Make the Brown Butter Frosting (Optional but SO worth it)

In a small saucepan, melt the butter over medium heat until it turns a golden brown and smells nutty—this takes about 4–5 minutes.
Remove from heat and slowly whisk in the powdered sugar, vanilla, and milk, 1 tablespoon at a time, until it reaches a smooth, spreadable consistency.

Flour

Spread the frosting over the cooled bars.

Serving & Storage Tips

• Cut into squares and serve at room temperature.

• Store in an airtight container at room temp for up to 3 days or refrigerate for longer freshness.

Bonus Tips
