How to Make Chunky Monkey Banana Cookies Recipe

Step 1: Preheat oven and prep your baking sheet

Get your oven warmed to a cozy 350 degrees, ensuring a perfect baking environment. Meanwhile, line a baking sheet with Reynolds Kitchens® Parchment Paper with SmartGrid® for effortless spacing.

💡 Pro Tip: Using parchment paper with gridlines helps space your cookies evenly, preventing overcrowding and irregular shapes.

Step 2: Whisk the dry ingredients

In a medium bowl, whisk together flour, oats, cinnamon, baking soda, salt, and just a pinch of nutmeg. This dry blend creates the flavorful backbone and provides texture contrast in your cookies.

💡 Pro Tip: Make sure your baking soda is fresh for the best rise and texture.

Step 3: Cream butter and sugars

In a large bowl, beat the softened butter with brown and white sugars for 2-3 minutes until it’s light and fluffy — this step traps air that makes your cookies tender.

💡 Pro Tip: Scrape the sides of the bowl occasionally so everything blends smoothly.

Step 4: Add bananas, vanilla, and eggs

Mix in your mashed bananas, vanilla extract, and eggs until the batter is perfectly combined. This adds moisture, sweetness, and binding all in one.

💡 Pro Tip: Mash bananas to a smooth consistency for even distribution in the dough.

Step 5: Combine wet and dry mixes

Gradually add your dry ingredient blend to the wet mixture, folding just until incorporated to avoid overworking the dough, which can make cookies tough.

💡 Pro Tip: Use a spatula to fold gently and preserve the lightness.

Step 6: Stir in chocolate chunks and walnuts

Finally, fold in the generous amounts of semi-sweet chocolate chunks and chopped walnuts. They bring indulgence and crunch to each cookie bite.

💡 Pro Tip: Reserve a few chunks to gently press on top of cookies before baking for a prettier presentation.

Step 7: Scoop out dough and bake

Use an ice cream scoop to portion dollops of cookie dough onto your prepared sheet, spacing them at least 2 inches apart using the gridlines. Bake for 10-12 minutes until the edges turn a gorgeous golden brown.

💡 Pro Tip: Don’t open the oven door early—this ensures the cookies bake evenly and rise properly.

Step 8: Cool and store

Let your cookies rest on the baking sheet for 3-4 minutes before transferring them to a cooling rack. This helps them firm up and prevents breakage. Store in an airtight container for up to 3 days or refrigerate for a week.

💡 Pro Tip: If you bake a big batch, separate layers with parchment to prevent sticking in storage.

Common Mistakes to Avoid

Learn from these common pitfalls to bake your Chunky Monkey Banana Cookies like a pro!

• Overmixing the dough: Can lead to tough cookies as gluten develops.
• Using underripe bananas: Lacks sweetness and moisture, resulting in bland, dry cookies.
• Skipping parchment paper: Cookies can stick or bake unevenly without it.
• Not spacing cookies properly: Leads to cookies merging into one giant pan cookie.
• Baking at the wrong temperature: Too hot and cookies burn on edges but stay raw inside; too low and they dry out.
• Removing cookies too quickly from the pan: Can cause them to break; let them cool slightly before moving.
