How to make Ultimate Chunky Monkey Banana Bars
Step 1: Prepare the oven and pan
Preheat oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
Step 2: Combine wet ingredients
In a large bowl, mash the ripe bananas. Add granulated sugar, brown sugar, melted butter, egg, and vanilla extract. Mix well until combined.
Step 3: Combine dry ingredients
In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
Step 4: Add the mix-ins
Fold in the chocolate chunks and chopped peanut butter cups.
Step 5: Bake the bars
Pour the batter into the prepared baking pan. Drop spoonfuls of peanut butter over the batter and swirl with a knife or toothpick.
Step 6: Bake
Bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
Step 7: Cool and cut
Let the bars cool completely in the pan before cutting into squares.
Tips for Success
- Don’t overmix the batter – this will result in tough bars. Mix until just combined.
- Use ripe bananas with brown spots for the best flavor and moisture.
- Line your baking pan with parchment paper for easy removal.
- Let the bars cool completely before cutting to prevent them from crumbling.
