  • Preheat oven to 350 degrees. Grease a 9×9 inch baking pan, or line it with aluminum foil.
  • Melt chocolate chips in a microwave-safe bowl by microwaving for 1 minute. Stir.
  • Cream butter and sugar for 2 minutes.
  • Add eggs and vanilla. Beat for 1 minute.
  • Add cooled chocolate. Beat until combined.

As bananas ripen they get sweeter. Be sure to use overripe bananas for the best results!
You can add extra chocolate chips to the top of the brownies if you want! Toffee chips are also amazing!
