Ingredients & Substitutions

Ingredient List

• 1 cup mashed banana (about 3 ripe bananas)
• ⅓ cup natural peanut butter
• ¼ cup pure maple syrup
• 2 tsp vanilla extract
• 1 egg
• 2 cups old-fashioned oats
• 1 tsp cinnamon
• 1 tsp baking powder
• ¼ tsp salt
• ½ cup dark chocolate chips

Notes on Quality

Use overripe bananas for the best sweetness and texture. Natural peanut butter (just peanuts and salt) works best here—no added sugars or oils. Old-fashioned rolled oats give these bars their hearty texture and help bind everything together.

Possible Substitutions

• Swap peanut butter for almond or cashew butter if you prefer or have allergies.
• Use flaxseed “egg” (1 tbsp flaxseed meal + 3 tbsp water) for a vegan version.
• Replace maple syrup with honey or agave if that’s what you have on hand.
• Toss in some chopped nuts or dried fruit for an extra flavor boost.

Step-by-Step Instructions

• Preheat your oven to 350°F (175°C).
• In a large mixing bowl, combine the mashed bananas, peanut butter, maple syrup, vanilla extract, and egg. Stir until smooth.

• Add in the oats, cinnamon, baking powder, and salt. Mix until everything is evenly incorporated.
• Fold in the dark chocolate chips.
• Pour the mixture into a greased or parchment-lined 8×8 baking dish and spread evenly.
• Bake for 25–30 minutes, or until the top is firm to the touch and golden around the edges.
• Let cool completely before slicing into 9 large or 16 smaller bars.

Expert Tips & Tricks

Best Practices

• Don’t overbake—these bars are best when they stay slightly soft in the center.
• Press the batter down firmly in the pan to get even, compact bars.
• Let them cool completely before slicing to avoid crumbling.

Common Mistakes

• Using under-ripe bananas: they won’t provide enough sweetness or moisture.
• Skipping the parchment paper: makes cleanup easier and bars easier to remove.
• Not measuring the oats properly: too much can make the bars dry.

Time-Saving Tips

• Mash the bananas directly in the mixing bowl to cut down on dishes.
• Make a double batch and freeze half for later.
• Mix everything in one bowl to minimize cleanup.

Serving Suggestions

Pairings

• Drizzle with a little extra melted peanut butter or chocolate before serving for extra flair.

Beverage Pairings

Storage & Reheating

Leftover Storage

Reheating Methods

Frequently Asked Questions

Substitutions & Adjustments

Can I make these vegan?
Yes! Just replace the egg with a flax egg (1 tbsp ground flax + 3 tbsp water, mixed and rested for 5 mins) and use dairy-free chocolate chips.

Can I use quick oats instead?
You can, but the texture will be softer and less chewy. Old-fashioned oats are best for that hearty bite.

You may have used too much oats or overbaked them. Stick to the 25–30 minute bake time and measure carefully.

They’re too soft to cut. How can I fix it?
Make sure to let them cool completely, or even chill them for 30 minutes before slicing.
