Banana Bread Brownies Ingredients

Combining your favorite banana bread flavor with the sweet taste of a banana sheet cake, you want to use flavorful bananas to make these banana bread brownies. You can easily keep bananas on hand by freezing your overripe bananas and storing them in the freezer for up to 3 months. When you are ready to use the frozen bananas, let them thaw in the refrigerator, drain off the excess moisture and then mash and use as directed.
Chocolate chips make a great addition to these brownies. You can add ¾ cup mini chocolate chips in addition to the walnuts, or even instead of the walnuts. Another option is to swap pecans for walnuts. If you aren’t a fan of nuts you can also simply leave them out.
You want the brownies to be warm but not too hot when you frost them. If you start making the frosting when you remove the banana bread brownies from the oven the timing should work out perfectly. Or, for a treat that’s slightly less sweet, you can even skip the frosting on top.
How to Make Banana Bread Brownies
FIRST STEP: Preheat oven to 350°F. Spray a 9x13-inch baking pan with non-stick cooking spray. Set aside.

THIRD STEP: In a large bowl, with an electric mixer, cream together the butter, brown sugar, and granulated sugar, until combined and fluffy.
FOURTH STEP: Add the eggs, mashed banana, buttermilk, and vanilla and mix well.
FIFTH STEP: Gradually add the flour mixture into the banana mixture, mixing until well combined.
SIXTH STEP: Stir in the chopped walnuts.
SEVENTH STEP: Pour the batter into the prepared baking pan and bake for 20 minutes, until the edges are golden, and a toothpick inserted in the center comes out with just a few crumbs.
EIGHTH STEP: In a small saucepan over medium heat, melt the butter and cook until it is a golden brown, and has a nutty aroma. Immediately remove from the heat and stir in the powdered sugar, half and half cream, and vanilla.
NINTH STEP: Using a silicone spatula spread the frosting over the warm banana brownies.

How can I ripen bananas quickly?
