Why Easy Banana Oatmeal Cookies Recipe Is Worth It

Easy Banana Oatmeal Cookies Recipe saves time because you mash, stir, and bake without a mixer. Ripe bananas add natural sweetness, keep the dough tender, and help the cookies hold together. You get pantry-friendly ingredients, minimal cleanup, and a snack that tastes like banana bread met your favorite oatmeal cookie.

Soft, cozy, and gone in a flash — my family asked for a double batch by the next day. ★★★★★

Ingredients You Need

Ingredients

• 2 large ripe bananas, well spotted for best sweetness
• 1/4 cup creamy peanut butter or almond butter (pantry shortcut: any smooth nut butter works)
• 2 tablespoons melted coconut oil or unsalted butter, cooled
• 1/4 cup light brown sugar or 3 tablespoons maple syrup
• 1 large egg or 1 flax egg (1 tablespoon ground flaxseed + 3 tablespoons water, rest 5 minutes)
• 1 teaspoon vanilla extract
• 1 teaspoon ground cinnamon
• 1/2 teaspoon baking powder
• 1/4 teaspoon fine salt
• 2 cups old-fashioned rolled oats (Quaker or Bob’s Red Mill; pick certified gluten-free oats if needed)
• 1/4 cup oat flour, only if you skip the egg or want extra structure
• 1/2 cup mix-ins: mini chocolate chips, chopped walnuts, pecans, raisins, or shredded coconut
  • Brand note: mini chips from Ghirardelli melt evenly; raisins from Sun-Maid stay plump

Equipment

• Mixing bowl and fork for mashing
• Rubber spatula
• 2 sheet pans lined with parchment or silicone mats
• Cookie scoop or 2 spoons
• Wire rack

Quick Tips & substitutions

• Use deeply speckled bananas for peak flavor and natural sweetness.
• Swap the egg with a flax egg for a vegan cookie; add the 1/4 cup oat flour for structure.
• Go gluten-free with certified gluten-free oats and verify add-ins.
• Choose old-fashioned oats for chew or quick oats for thinner, more tender cookies.
• Rest the mixed dough 5 minutes so the oats hydrate and the scoop holds shape.
• Flatten the scoops slightly since these cookies do not spread much.
• Keep the dough cool if the kitchen runs warm; chill 10 minutes to prevent excess spread.
• Stir in 1 to 2 tablespoons mini chips per dozen cookies for balanced chocolate in every bite.
• Sweeten to taste: use more banana and skip the brown sugar for a lighter, breakfast-style cookie.

How to Make Easy Banana Oatmeal Cookies Recipe

Step 1: Prep the oven

• Heat the oven to 350 degrees F. Line sheet pans with parchment.

Step 2: Mash and mix the wet ingredients

• Mash the bananas in a large bowl until mostly smooth.
• Whisk in peanut butter, melted coconut oil or butter, brown sugar or maple, egg or flax egg, vanilla, and cinnamon until creamy.

Step 3: Add the dry ingredients

• Stir in baking powder and salt.
• Fold in oats and, if using, oat flour. Mix until the dough looks thick and scoopable.
• Let the dough rest 5 minutes so the oats drink up moisture.

Step 4: Add mix-ins and portion

• Fold in chocolate chips, nuts, or raisins.
• Scoop heaping 1.5 tablespoons per cookie onto the prepared pans, spacing about 2 inches apart.
• Press each mound to about 1/2 inch thick for even baking.

Step 5: Bake and cool

• Bake 11 to 13 minutes, until the edges set and the bottoms turn light golden.
• Let the cookies cool on the pan 5 minutes, then move them to a rack.
• Enjoy warm or at room temp. The centers stay soft and chewy.

Variations

• Chocolate Chip Banana Oat: Add 2/3 cup mini chocolate chips and a pinch of espresso powder.
• Walnut Raisin: Stir in 1/3 cup chopped walnuts and 1/3 cup raisins; add a dash of nutmeg.
• Peanut Butter Lover: Swap almond butter with peanut butter and drizzle cooled cookies with warmed peanut butter.
• Trail Mix: Fold in pumpkin seeds, sunflower seeds, and chopped dried cherries.
• Coconut Almond: Add 1/3 cup shredded coconut and 1/3 cup sliced almonds; bump vanilla to 1.5 teaspoons.

Ways to Serve

• Pair with Greek yogurt and berries for a quick breakfast.
• Pack with string cheese or a latte for an afternoon snack.
• Sandwich two cookies with vanilla ice cream for dessert.
• Crumble over vanilla yogurt with honey.
• Spread with peanut butter or almond butter and top with banana slices.

Storage

Cool the cookies completely, then store them in an airtight container at room temperature for 3 days with a paper towel to catch moisture. Refrigerate for up to 1 week for a firmer, chewier bite. Freeze on a sheet pan, then bag and keep for up to 3 months; thaw at room temp or warm in a 300 degrees F oven for 5 to 7 minutes. I reheat a couple in the toaster oven for a cozy, just-baked feel.

Ingredients

  

• 2 large ripe bananas, well spotted
• 1/4 cup creamy peanut butter or almond butter
• 2 tablespoons melted coconut oil or unsalted butter, cooled
• 1/4 cup light brown sugar or 3 tablespoons maple syrup
• 1 large egg or 1 flax egg (1 tablespoon ground flaxseed + 3 tablespoons water, rested 5 minutes)
• 1 teaspoon vanilla extract
• 1 teaspoon ground cinnamon
• 1/2 teaspoon baking powder
• 1/4 teaspoon fine salt
• 2 cups old-fashioned rolled oats
• 1/4 cup oat flour (optional, for extra structure or if skipping the egg)
• 1/2 cup mix-ins such as mini chocolate chips, chopped walnuts, pecans, raisins, or shredded coconut

Instructions

 

1. Heat the oven to 350 degrees F and line 2 sheet pans with parchment paper or silicone mats.
2. In a large mixing bowl, mash the ripe bananas with a fork until mostly smooth.
3. Whisk in the peanut butter or almond butter, melted coconut oil or butter, brown sugar or maple syrup, egg or prepared flax egg, vanilla extract, and ground cinnamon until the mixture is creamy and well combined.
4. Stir in the baking powder and salt, then fold in the rolled oats and, if using, the oat flour until a thick, scoopable dough forms.
5. Let the dough rest for about 5 minutes so the oats can absorb some of the moisture.
6. Fold in your choice of mix-ins, such as mini chocolate chips, nuts, raisins, or shredded coconut.
7. Scoop heaping 1 1/2 tablespoon portions of dough onto the prepared baking sheets, spacing them about 2 inches apart.
8. Gently flatten each scoop to about 1/2 inch thick to help the cookies bake evenly, as they will not spread much in the oven.
9. Bake for 11 to 13 minutes, or until the edges are set and the bottoms are light golden brown.
10. Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely. Enjoy warm or at room temperature; the centers will stay soft and chewy.
