3-Ingredient Banana Oat Cookies (Easy Healthy Lunchbox Cookies)
These 3-ingredient banana oat cookies are soft, naturally sweet, and made with just ripe bananas, rolled oats, and a dash of cinnamon. Baked in only 12 minutes, they require no refined flour, eggs, or added granulated sugar. They offer a wholesome lunchbox alternative to packaged store-bought treats that kids love eating.
Instructions
- 01
Preheat & Prep Sheet: Preheat your oven to 350°F (175°C) and line a large flat baking sheet with unbleached parchment paper.
- 02
Mash Bananas: In a medium mixing bowl, peel the ripe bananas and mash vigorously with a sturdy fork until completely smooth and liquefied.
- 03
Stir in Oats & Spice: Add the rolled oats, ground cinnamon, vanilla extract, and pinch of salt. Stir with a spatula until oats absorb the banana puree and a sticky dough forms.
- 04
Fold in Chocolate Chips: Gently stir in mini dark chocolate chips or raisins if using.
- 05
Portion & Shape: Scoop 10 equal portions (about 1 1/2 tablespoons each) onto the baking sheet. Flatten gently with the back of a spoon into round cookie discs (they will not spread while baking).
- 06
Bake & Cool: Bake for 12 to 14 minutes until tops feel set and bottom edges turn light golden brown. Cool on the pan for 5 minutes, then transfer to a wire rack.
- ✦Use Heavily Spotted Bananas: The browner and riper the bananas, the sweeter and softer the finished cookies will be without adding any syrup.
- ✦Shape Before Baking: Because these cookies contain no butter or baking powder, they do not spread in the oven; shape them into your desired thickness before baking.
- ✦Cool Thoroughly Before Packing: Allow cookies to cool 100% on a wire rack so steam evaporates, ensuring a chewy texture that will not get soggy in lunchboxes.

Frequently Asked Questions
Q: Can I use steel-cut oats instead of rolled oats?
A: No, steel-cut oats are too dense and hard to hydrate in this recipe. Use old-fashioned rolled oats or quick-cooking oats for the best tender texture.
Q: How do I store leftover banana oat cookies?
A: Store in an airtight container lined with a paper towel in the refrigerator for up to 5 days, or freeze in an airtight bag for up to 2 months.
