Why Banana Oatmeal Cookies Are a Healthy Choice

Banana Oatmeal Cookies are more than just delicious—they’re also a smart choice for anyone pursuing a healthier lifestyle. The bananas provide natural sweetness and are packed with potassium and vitamin B6, which support heart and muscle health. Oats are a wonderful source of fiber and can help regulate blood sugar levels, keeping you full and energized for longer.

In addition, walnuts bring healthy fats and plant-based protein to the mix, along with omega-3s that benefit brain health. With no added sugar or oil, this recipe fits perfectly into any list of healthy recipes. If you’re looking for a snack that supports your clean eating goals without sacrificing taste, these cookies are a winner.

Ingredients for Banana Oatmeal Cookies

You only need three ingredients to make these wholesome cookies:

2 medium ripe bananas, mashed
1 cup of uncooked quick oats*
1/4 cup crushed walnuts

*Note: You can substitute rolled oats if quick oats aren’t available, but the texture will be slightly chewier.

Want to mix things up? Add-ins like cinnamon, dark chocolate chips, or dried cranberries are great optional extras. Just keep the additions minimal to maintain the health benefits.

Nora’s Tips for Perfect Banana Oatmeal Cookies

Want to take your cookies to the next level? Here are my best tips:

Use overripe bananas: The riper they are, the sweeter and more flavorful your cookies will be.
Add a pinch of salt: It enhances the natural sweetness and deepens the flavor.
Make it fun: Add a handful of mini chocolate chips or coconut flakes for a touch of indulgence.
Storage: Keep leftovers in an airtight container for up to 3 days at room temperature, or freeze for up to 1 month.
