Ingredients for 3-Ingredient Chocolate Oat Cookies
You’ll only need:
- 2 large ripe bananas, mashed
- 1 1/2 cups rolled oats
- 1/3 cup unsweetened cocoa powder
That’s it! Three ingredients you probably already have sitting in your kitchen.
Ingredient Notes
Bananas: The riper, the better. Look for bananas with brown spots—they’re sweeter and mash beautifully.
Rolled Oats: Old-fashioned rolled oats work best for texture. Quick oats can be used in a pinch, but the cookies will be softer.
Unsweetened Cocoa Powder: Use high-quality cocoa powder for the richest flavor. Dutch-processed or natural both work well.
Necessary Tools for Preparation
You won’t need anything fancy:
- Mixing bowl
- Fork or potato masher
- Spoon or cookie scoop
- Baking sheet
- Parchment paper or silicone baking mat
Simple tools for a simple recipe—just the way I like it.
Possible Additions and Substitutions

- Chopped nuts (walnuts or almonds are amazing!)
- Peanut butter or almond butter swirl
- Shredded coconut
- A pinch of sea salt on top
Substitutions
- Swap cocoa powder for cacao powder for a richer taste.
- Replace 1/4 cup oats with protein powder for added protein.

Don’t be afraid to experiment—this recipe is incredibly forgiving.

Frequently Asked Questions
Can I use quick oats instead of rolled oats?
Yes! The texture will be softer and slightly less chewy, but they’ll still be delicious.
Can I make these without cocoa powder?
Cocoa powder is essential for the chocolate flavor. If you omit it, you’ll need to adjust the oats and possibly add sweetener.
Are these cookies gluten-free?
They are if you use certified gluten-free oats.
Can I add sweetener?
You can add 1–2 tablespoons of maple syrup or honey if you prefer a sweeter cookie, but very ripe bananas usually provide enough sweetness.
Why are my cookies too soft?
They may need an extra minute in the oven, or they may not have cooled fully yet. They firm up as they cool.
