Banana Bread Brownies

Banana bread brownies are fudgy banana bars with a crinkled top crust and a brown butter glaze poured over while warm. The glaze soaks into every inch for moist, dense banana bars with a rich, nutty finish.

Ingredients
  

Banana bread brownie batter
  • 3 ripe bananas Mash until smooth.
  • 0.5 cup unsalted butter Brown and cool slightly.
  • 1 cup brown sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 1.5 cup all-purpose flour
  • 1 tsp baking soda
  • 0.5 tsp cinnamon
  • 0.25 tsp salt
  • 0.5 cup chocolate chips
Brown butter glaze
  • 3 tbsp butter Brown for the glaze.
  • 1 cup powdered sugar
  • 2 tbsp milk
  • 0.5 tsp vanilla

Equipment

  • 1 sheet pan
  • 1 saucepan

Method
 

Prep and pan
  1. Preheat the oven to 350°F and grease a 9x13 pan.
  2. Brown the 1/2 cup unsalted butter in a saucepan until golden and nutty smelling, then remove from heat and cool slightly.
Make the batter
  1. Whisk the browned butter, brown sugar, eggs, and vanilla into the mashed ripe bananas until smooth.
  2. Fold in the all-purpose flour, baking soda, cinnamon, and salt until just combined, then stir in the chocolate chips.
  3. Spread the batter evenly in the prepared 9x13 pan and bake for 25–30 minutes, until a toothpick comes out with just a few moist crumbs.
Brown butter glaze and finish
  1. Brown the 3 tablespoons butter in a saucepan until nutty and golden, then whisk with powdered sugar, milk, and vanilla until smooth.
  2. Pour the glaze over the warm bars so it soaks in, then slice when set.

Notes

For the fudgiest texture, avoid overbaking—pull the bars when the toothpick has just a few moist crumbs. Store covered at room temperature up to 2 days or refrigerated up to 5 days; freeze in an airtight container up to 2 months. If you want a dairy-light swap, use a milk alternative for the glaze while keeping the butter-based browning for best flavor.
