Easy 3-Ingredient Oat Cookies for Busy Days

How to Make 3-Ingredient Oat Cookies

Step 1: Mash the Bananas

Start by thoroughly mashing the ripe bananas in a large bowl until they form a smooth, slightly chunky puree. This natural sweetener and binder is the foundation of your cookies.

Step 2: Mix in the Nut Butter

Add your chosen nut butter to the mashed bananas and stir well until fully combined. This adds moisture, richness, and helps hold the cookies together.

Step 3: Fold in the Rolled Oats

Gently fold the rolled oats into the banana and nut butter mix. The oats provide structure and a hearty chew, making these cookies super satisfying.

Step 4: Shape the Cookies

Using a spoon or your hands, scoop out small portions and shape them into cookie rounds on a parchment-lined baking sheet. Leave some space between each for even baking.

Step 5: Bake to Perfection

Bake the cookies in a preheated oven at 350°F (175°C) for about 12-15 minutes or until they’re just golden around the edges. Let them cool slightly before enjoying.

Pro Tips for Making 3-Ingredient Oat Cookies

Use Very Ripe Bananas: The sweeter and softer they are, the better the flavor and texture.
Choose Creamy Nut Butter: Smooth nut butter blends more easily and produces a softer cookie.
Don’t Overmix: Gently combine ingredients to keep a chewy texture instead of dense.

Size Matters: Keep cookies uniform in size for even baking and consistent results.
Watch Baking Time: Slightly underbaked cookies remain chewy; bake extra minutes if you prefer crisp edges.

How to Serve 3-Ingredient Oat Cookies

Garnishes

Sprinkle a pinch of sea salt or a dusting of cinnamon on top after baking to enhance flavor and add a gourmet touch that’s simple but delightful.

Side Dishes

Pair these cookies with a cup of hot herbal tea, cold milk, or a berry smoothie for a balanced snack that satisfies cravings and keeps energy steady throughout your busy day.

Creative Ways to Present

Stack the cookies on a pretty plate lined with parchment paper, or package them in resealable bags tied with twine as thoughtful homemade gifts for friends and family.

Make Ahead and Storage

Storing Leftovers

Keep leftover cookies in an airtight container at room temperature for up to 3 days. They stay chewy and fresh, perfect for grabbing on the go.

Freezing

For longer storage, freeze the cookies in a single layer on a baking sheet before transferring to a sealed freezer-safe bag. This method keeps them from sticking and extends freshness for up to 3 months.

Reheating

Reheat frozen or stored cookies in a warm oven for 5-7 minutes or in a microwave for 15-20 seconds to restore a just-baked softness that tastes like they were made moments ago.

FAQs

Can I use quick oats instead of rolled oats?

Yes, quick oats can be used but they will create a softer and less chewy cookie since they absorb moisture faster and break down more during baking.

Are these cookies gluten-free?

They can be gluten-free if you use certified gluten-free rolled oats to avoid any contamination, making them safe for those with gluten sensitivities.

Is it necessary to bake these cookies?

Baking is recommended to improve texture and bring out the flavors, but you can also enjoy a no-bake version by chilling shaped cookies until firm.

Can I substitute the nut butter with sunflower seed butter?

Absolutely, sunflower seed butter works well as a nut-free alternative, providing similar creaminess and binding properties.

How do I make the cookies less sweet?

Since bananas provide the main sweetness, choose less ripe bananas or reduce the amount slightly, but remember it will affect the cookie’s moisture and binding.
