Ingredients You’ll Need

Here’s what you’ll need for these chewy banana bars:

How To Make Chocolate Chip Banana Bars

Preheat oven to 350°F and line an 8×8 inch pan with parchment paper.
Melt butter in the microwave for about a minute, stir, then cool for 10-15 minutes.

Meanwhile, whisk together flour, baking powder, and salt.
In a large bowl, whisk cooled butter and light brown sugar until smooth.
Next, whisk in the egg, mashed bananas, and vanilla until fully combined (it might look a little curdled — that’s okay!).

Then, stir in dry ingredients gently until just combined.
Fold in most of the mini chocolate chips, saving a handful for sprinkling on top.
Spread batter evenly into the prepared pan, sprinkle remaining chips, and bake for 30–35 minutes until golden around the edges and a toothpick comes out clean or with just a few moist crumbs.

Cool completely before lifting from pan and slicing.

Storage and Freezing Instructions
