Banana Bars recipe

Do you ever feel like you get tired of making the same ol’ banana bread recipe? Sometimes, you need a new way to use those over-ripe bananas. This Chocolate Banana Bars recipe is sure to be a hit with the whole family!

For this recipe, a simple from-scratch banana mixture is split in half to create the two-tone effect. The chocolate layer is placed in the pan first; then, the plain banana layer is placed on top before being baked to yummy perfection.

It’s kid-tested and mother-approved! 😉 I hope you give this recipe a try soon!

How to ripen bananas faster

There are two methods to help speed up ripening if your bananas aren’t quite ripe enough yet:

• MICROWAVE: Poke the unpeeled bananas all over with a fork or knife. PLace them on a microwave-safe plate and microwave on HIGH power for 30-second increments until the bananas are as soft as you would like. Allow to cool before using in recipes.
• OVEN: Prehat the oven to 300°F. Place your bananas on a rimmed baking sheet and bake the bananas until their peels turn black. Allow to cool before using in recipes.

How to make Chocolate Banana Bars

1. Preheat oven to 350°F. Grease a 9×13-inch baking pan and set aside.
2. In a large mixing bowl, cream the butter and granulated sugar with an electric mixer on low speed. Add the egg and vanilla. Continue to mix on medium speed until thoroughly combined. Blend in the bananas. Scrape down the sides of the bowl with a rubber spatula and mix for one minute more.
3. In a separate bowl, combine the flour, baking powder, baking soda, and salt. Add the flour mixture to the banana mixture and mix well, scraping down the sides of the bowl once with a rubber spatula.
4. Divide the batter in half. Add cocoa powder to half of the batter and mix well. Spread the cocoa mixture into the prepared pan. Carefully spoon the plain batter on top of the cocoa batter and carefully spread it out, trying not to mix the two layers.
5. Bake for 25 minutes or until a toothpick inserted near the center tests clean. Remove to a wire rack to cool completely.
6. To serve, cut into bars.
