If you love sweet, soft, and healthy treats, banana peanut butter oatmeal cookies are perfect. They are easy to make, delicious, and fill your kitchen with a wonderful smell. These cookies are soft, chewy, and naturally sweet from bananas. Everyone, even kids, will enjoy them. They are also a great snack or breakfast treat that gives energy.
Choosing the Best Ingredients for Banana Peanut Butter Oatmeal Cookies
Pick Ripe Bananas
Ripe bananas are very important. They are soft and sweet. Do not use green or hard bananas. The softer the banana, the easier it is to mash. Sweet bananas make the cookies taste natural. Too ripe bananas may be very soft, but they will make cookies extra sweet. Make sure the bananas do not smell sour.
Select Natural Peanut Butter
Natural peanut butter without sugar or hydrogenated oils is best. It gives a strong peanut taste. Smooth peanut butter is easier to mix, but chunky can add texture. Stir it well if oil separates. Avoid peanut butter with too much sugar. It makes cookies too sweet and changes the texture.
Choose the Right Oats
Old-fashioned rolled oats are perfect. They hold shape and make cookies chewy. Instant oats make cookies soft and thin. Steel-cut oats are too hard and will not cook well. Measure oats carefully. Too many oats make cookies dry. Too few oats make cookies flat.
Use Simple Add-Ins
You can add chocolate chips, raisins, or nuts. Keep add-ins small. Chocolate chips melt in the oven. Nuts add crunch. Do not add too much. Too many add-ins make cookies break.
Preparing Your Kitchen and Baking Tools
Clean and Clear Counter
Clear space on your counter. Wash all bowls, spoons, and trays. A clean space helps to work fast. Make sure you have enough room to mix ingredients.
Use Mixing Bowls and Spoons
Use medium or large bowls. Big bowls make mixing easy. Wooden spoons or silicone spatulas work best. They help to mix sticky peanut butter and mashed bananas.
Prepare Baking Sheet
Line your baking sheet with parchment paper. It prevents cookies from sticking. You can also use a silicone mat. Greasing is not needed if using parchment paper.
Preheat Oven
Preheat your oven to 350 degrees Fahrenheit. Oven should be ready when cookies go in. Warm oven helps cookies bake evenly. Do not skip preheating. Cold oven makes cookies flat.

Mixing Ingredients for Perfect Cookie Dough
Mash Bananas Well
Peel bananas and put in a bowl. Mash with a fork until smooth. Small lumps are okay. Do not leave big chunks. Smooth bananas mix better with peanut butter.
Combine Peanut Butter and Banana
Add peanut butter to mashed bananas. Stir slowly. Make sure mixture is even. Mix until creamy and sticky. This is the base of your cookie dough.
Add Oats Slowly
Add oats to the banana and peanut butter mixture. Stir gently. Make sure all oats are coated. Dough should be thick but soft. Too dry dough means more banana or peanut butter needed.
Mix Optional Ingredients
Add chocolate chips, nuts, or raisins. Fold gently. Do not stir too much. Overmixing makes cookies hard. Mix just enough to spread ingredients evenly.

Scoop Dough Evenly
Use a spoon or ice cream scoop. Scoop same size for all cookies. It helps them bake evenly. Place cookies two inches apart on tray.
