Storage Tips: Keep fresh: Store leftovers in an airtight container at room temperature for up to 3 days for optimal freshness!

Chunky Monkey Brownies Recipe FAQs
What type of bananas should I use for Chunky Monkey Brownies?
Absolutely, for the best flavor, use ripe bananas! The riper your bananas are, the sweeter and more flavorful your brownies will taste. Look for bananas with brown spots; this indicates they’re perfectly ripe and will yield the best results in your brownies.
How should I store my Chunky Monkey Brownies?
To keep your brownies fresh, store them in an airtight container at room temperature for up to 3 days. If you want to enjoy these treats for a longer period, you can refrigerate them, where they’ll last for up to a week. Just make sure they are well-wrapped to prevent drying out!

What if my brownies are too cakey or dry?
If your brownies turn out too cakey or dry, it may be due to overmixing the batter or baking them too long. Remember to mix just until incorporated and rely on the toothpick test; remove them from the oven when the toothpick comes out with a few moist crumbs. You can also add an extra tablespoon of mashed banana next time for added moisture!
Are Chunky Monkey Brownies suitable for people with allergies?
It’s important to note that this recipe contains ingredients like eggs and gluten, which may not be suitable for everyone.
