For the Banana Bread Brownies:

  • 1/4 cup sugar
  • 1 cup greek yogurt (can substitute sour cream)
  • 1/2 cup butter (room temperature)
  • 2 large eggs
  • 3-4 ripe bananas (mashed)*
  • 2 tsp vanilla extract
  • 2 cups all purpose flour
  • 1 tsp baking soda
  • 3/4 tsp salt
  • 1/2 cup walnuts, chopped (optional - sub for chocolate chips if you like)

For the Brown Butter Glaze:

  • 1/4 cup butter
  • 2 cups icing sugar
  • 1 1/2 tsp vanilla extract
  • 3 tbsp milk


For the Banana Bread Brownies:

  • Keep the butter and eggs out to come to room temperature while you mash the bananas and set out the other ingredients.
  • Heat oven to 375*F (109*C).
  • Grease and line a 9x9 inch square baking pan with parchment.
  • In a large bowl, cream 1/2 cup butter with 1/4 cup sugar till light and fluffy.
  • Add 1 cup yogurt, and 2 eggs and whisk till smooth and combined.
  • Blend in 3-4 mashed bananas, 2 tsp vanilla extract.
  • With a spatula, fold in the 2 cups flour, 1 tsp baking soda, 3/4 tsp salt till just combined.
  • Fold in 1/2 cup walnuts, if using.
  • Spread batter into the prepared pan and bake for 30-35 minutes. It will be golden brown on top and a wooden toothpick inserted in the centre comes out clean.
  • While the banana bread bakes, make the glaze.

For the Brown Butter Glaze:

  • Heat a 1/4 cup butter in saucepan over medium high heat.
  • Once it comes to a boil, keep an eye on it. Swirling constantly. Once you note the butter turn from light yellow to golden brown, and it starts to get nice and fragrant, take it off the heat (so it doesn't burn).
  • Mix the browned butter with 2 cups icing sugar, 1 1/2 tsp vanilla extract, and 3 tbsp milk.
  • Mix till the glaze is nice and smooth. It will be like a thick honey consistency.

Glaze the Banana Bread Brownies

  • Once done cooking, allow the banana bread to cool 15-20 mins till it is still warm, but cool enough to handle. Plate the banana bread and spread the glaze over top while it is still warm, so it will be easier to spread.
  • Cut into small squares and serve warm or at room temperature.


*Freeze your mashed bananas for later. Just let it come to room temp before baking in this recipe.
