Wholesome Ingredients for These Banana Oatmeal Cookies

Let’s take a closer look at the key ingredients that make these healthy banana oatmeal cookies both nutrient-rich and utterly delicious:

Bananas: Ripe bananas act as a natural sweetener, reducing the need for added sugar while adding moisture. Tip: Look for bananas with plenty of brown spots for the best flavor and sweetness.
Oats: Oats are a nutritional powerhouse, packed with fiber, beta-glucans, and slow-digesting carbs. Choose quick-cooking oats for a softer texture or old-fashioned oats for a chewier bite.
Walnuts: These add heart-healthy omega-3 fatty acids and crunch. If you’re nut-free, replace them with sunflower seeds or skip them entirely.
Butter: While we use softened butter in the base recipe for its creamy richness, you can swap it for coconut oil to keep the cookies vegan.

Batch baking: Double the recipe and freeze extras for an easy healthy snack later!
