3 Ingredient Banana Oatmeal Cookies (No Egg, No Flour)

Why You’ll Love This Recipe

I love these 3 Ingredient Banana Oatmeal Cookies because they’re super simple to make and don’t require any complicated ingredients. The bananas provide natural sweetness, while the oats give them a hearty texture and boost of fiber. Plus, with just three ingredients, they come together quickly—perfect for busy mornings or a healthy snack. You can also customize the cookies by adding your favorite mix-ins like nuts, seeds, or even chocolate chips for extra flavor and texture.

Ingredients

2 ripe bananas (about 200g)

1 cup rolled oats (old-fashioned or quick cooking)

1 teaspoon ground cinnamon

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking tray with parchment paper or a silicone baking mat to prevent the cookies from sticking.

Mash the Bananas: Peel and mash the bananas in a medium bowl using a potato masher or fork. Make sure the bananas are well-mashed with only small chunks remaining.

Mix the Ingredients: Stir in the rolled oats and cinnamon. Set the mixture aside for a few minutes to allow the oats to soak up the moisture from the bananas. If the batter feels too wet, add 1-2 tablespoons more oats to thicken it up.

Shape the Cookies: Using a spoon, drop spoonfuls of the batter onto the prepared baking tray. Shape the cookies with your fingers, as they won’t spread while baking. This recipe makes about 8 medium-sized cookies (3 inches wide).

Add Optional Toppings: If desired, top the cookies with any extras such as dark chocolate chips, nuts, seeds, or a smear of fruit preserves.

Bake the Cookies: Bake the cookies for 17 minutes or until they’re golden brown and firm to the touch. Note: If you’re making smaller cookies (around 2 inches wide), reduce the baking time by 3-5 minutes. For larger cookies (about 4 inches wide), increase the baking time by 2-3 minutes.

Cool and Serve: Remove the cookies from the oven and let them cool slightly before enjoying.

Servings and Timing

This recipe makes 8 medium-sized cookies. Prep time is about 10 minutes, and cook time is around 17 minutes, so the total time is approximately 27 minutes.

Variations

Flavors: Instead of cinnamon, you can use vanilla extract (1 teaspoon), pumpkin spice seasoning (1 teaspoon), or a mix of cardamom (¼ teaspoon) and cinnamon (¼ teaspoon).

Toppings: Customize your cookies with chocolate chips, chopped nuts (walnuts, pecans), seeds (sunflower, flax), or dried fruits (raisins, cranberries). A smear of fruit preserves or jam can add extra sweetness!

Sweeteners: If you prefer a sweeter cookie, you can add a teaspoon of honey or maple syrup to the batter.

Storage/Reheating

Storage: Store the cookies in an airtight container at room temperature for up to 3 days.

Freezing: These cookies freeze well. After baking, let them cool completely, then wrap them in plastic wrap and place them in a freezer-safe bag for up to 2 months. Thaw at room temperature before enjoying.

Reheating: To reheat, place the cookies in the microwave for about 10-15 seconds or in the oven at 350°F for 5-7 minutes until warmed through.
