Add a little of the flour mixture and carefully stir into the chocolate mixture with a spatula, do not over mix or incorporate air into the batter. Continue until all the flour mixture has been added.
Line an 8x8" baking pan with parchment paper then pour the brownie batter into the pan. Use the spatula to smooth the top out until even.

Notes
It's important not to incorporate too much air into a brownie batter so that it doesn't sink in the middle.Using overripe bananas will make for a sweeter banana flavor for these chocolate banana brownies.Serve with a scoop of vanilla ice cream.
