If you love sweets but you also prioritize a healthy plant-based diet, I have the PERFECT dessert for you! These peanut butter banana oatmeal cookies are packed with fiber, vitamins, minerals, and contain no added sugar. I’m willing to bet these are the healthiest cookies you’ll ever eat.

What’s so great about these cookies? The wholesome recipe finally lets you consume cookies for breakfast! That’s right – cookies for breakfast. (Yum!) The nutritious ingredients provide long-lasting energy to power your day. Grab a cookie for an on-the-go breakfast, as a midday pick-me-up, or devour one to satisfy your post-dinner sweet tooth.

Only 3 ingredients are required for this easy cookie recipe: rolled oats, overripe bananas, and peanut butter. You can add your favorite mix-ins, like chocolate chips, nuts, and dried fruit. I recommend including a dash of cinnamon, vanilla extract, and a pinch of salt as flavor enhancers. All of these add-ins are entirely optional – the cookies are perfectly delicious with just the 3 required ingredients.

Ingredients in these healthy breakfast cookies

• Oats: This recipe contains rolled oats instead of flour. Oats contain various nutrients, including magnesium, vitamin B1, and iron. They are also packed with fiber and provide a good amount of plant-based protein.
• Banana: Overripe bananas act as a natural sweetener. For the sweetest flavor, be sure to use bananas that have yellow peels with brown specks all over them.
• Peanut butter: Peanut butter helps bind the oats and bananas together while providing healthy fats. You can substitute the peanut butter with any other type of nut butter. Try almond butter, cashew butter, or sunflower seed butter for a nut-free option.
• Chocolate chips: Although they are optional, I highly recommend adding chocolate chips to these banana oatmeal cookies.
• Vanilla extract: A dash of vanilla extract is also optional.
• Cinnamon: Add a pinch of cinnamon for warm flavor and anti-inflammatory properties.
• Salt: Salt helps balance the other flavors.

Combine mashed bananas and peanut butter

In a large bowl, combine the mashed banana, peanut butter, vanilla extract, cinnamon, and salt. Mix the ingredients together until well combined.

Add rolled oats and chocolate chips

Next, toss in the rolled oats. Stir ingredients until the oats are evenly incorporated. Then, fold in the chocolate chips (or your choice of mix-ins).

Scoop the banana oatmeal cookie dough

Scoop the cookie dough into 8 rounds. Transfer to a parchment paper-lined baking sheet.

Bake the cookies

Using clean hands or a spoon, flatten the balls of dough and shape them into cookies. They do not spread in the oven, so form them before baking.

Bake the cookies at 350 degrees F for 15 minutes. After, remove them from the oven and cool for a few minutes. Enjoy with a glass of almond milk!

Mix-ins and add-ins

We all love chocolate chips, but you may be wondering… what can you put in cookies instead of chocolate? There are several options to choose from.

• Nuts: add crushed nuts, such as walnuts, pecans, peanuts, or cashews
• Dried fruit: replace the chocolate chips with raisins, cranberries, dried blueberries, or goji berries
• Coconut: sprinkle shredded coconut or coconut flakes into the cookie dough
• Cacao nibs: cacao nibs are a healthy alternative to chocolate chips
• Seeds: toss in a handful of pumpkin seeds, chia seeds, hemp seeds, or flax seed
• Pretzels: crushed pretzels create a yummy sweet & salty combo (potato chips work, too!)
• Spices: in addition to cinnamon, add a pinch of nutmeg, ginger, or pumpkin spice
• Sprinkles: toss in rainbow sprinkles for colorful cookies
• Cocoa: turn the recipe into double chocolate cookies by adding 1-2 tablespoon cocoa powder
