How to Make Banana Peanut Butter Chip Bars

Step 2: Mix the Wet Ingredients
Peel and mash the bananas in a large mixing bowl.
Add the brown sugar, vegetable oil, peanut butter, eggs, and vanilla extract. Stir until well combined.
Step 3: Add the Dry Ingredients
Add the flour, baking soda, and salt.
Mix until just combined, being careful not to overmix.
Fold in half of the chocolate chips.
Step 4: Bake
Spread the batter evenly into the prepared pan.
Sprinkle the remaining chocolate chips over the top.

Allow the bars to cool completely before cutting into squares.
Serve as-is or with a glass of cold milk for the ultimate treat.
Tips for the Best Banana Peanut Butter Chip Bars
Use Very Ripe Bananas
The darker and softer the bananas, the sweeter and more flavorful your bars will be.
Don’t Overmix the Batter
Mix only until the ingredients are combined to keep the bars tender and soft.
Line the Pan with Parchment Paper
Parchment makes it easy to lift the bars from the pan and cut clean squares.
Measure Flour Correctly
Too much flour can make the bars dry. Spoon flour into the measuring cup and level it off rather than scooping directly from the bag.
