How to Make Banana Peanut Butter Chip Bars

Step 1: Prepare the Pan

Preheat your oven to 350°F.

Spray a 15 x 10½-inch jelly roll pan with non-stick cooking spray or line it with parchment paper.

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.

Bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean.

Step 5: Cool and Serve

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.

Variations

Replace some or all of the chocolate chips with peanut butter chips for extra peanut butter flavor.

Double Chocolate Banana Bars

Add ¼ cup cocoa powder and use chocolate chunks instead of chips.

Banana Nut Bars

Stir in ½ cup chopped walnuts or pecans.

Mini Chocolate Chip Bars

Use mini chocolate chips for more chocolate in every bite.

Cinnamon Banana Bars

Add 1 teaspoon ground cinnamon for a warm banana bread flavor.

Storage

Store Banana Peanut Butter Chip Bars in an airtight container at room temperature for up to 3 days.

For longer storage, refrigerate for up to 1 week.

Can You Freeze Banana Peanut Butter Chip Bars?

Yes.

Allow the bars to cool completely, then wrap tightly and freeze for up to 3 months.

Thaw at room temperature before serving.

Frequently Asked Questions

Can I use natural peanut butter?

Yes, but regular creamy peanut butter typically provides the best texture and consistency.

Can I make these without chocolate chips?

Absolutely. The bars are still delicious with just the banana and peanut butter flavors.

How ripe should the bananas be?

The bananas should be heavily spotted or mostly brown. Overripe bananas provide the sweetest flavor and softest texture.

Can I make these ahead of time?

Yes. These bars stay moist for several days and are perfect for making ahead.

Can I turn this into banana bread?

This recipe is designed for bars, but the batter can often be adapted for loaf pans by increasing the baking time.
