How To Make 4-Ingredient Banana Oatmeal Cookies

Ingredients
Here’s what you need to make them:
- Ripe Banana – The darker the skin, the better the cookies will be. Don’t hesitate to use black bananas for this recipe. They give the best sweet flavors without adding sugar to the recipe.
- Rolled Oats or old-fashioned oats. You can use either. Quick oats have a finer texture that kids prefer, but old-fashioned oats are also delicious.
- Nut Butter like peanut butter, almond butter, or even sunflower seed butter for a nut-free option.
- Dark Chocolate Chips or dried fruits like dried raisins or dried cranberries.
Preparation
The recipe is easy and straightforward. First, mash the bananas and place them in a large mixing bowl along with the peanut butter and oats.
You don’t have to measure the mashed bananas, as long as you take one medium-sized one.
Stir with a spoon or silicone spatula until it comes together into a sticky batter.
Then, stir the chocolate chips, dried fruits, or chopped nuts into the batter.
Stir until they are all evenly incorporated.
Baking The Cookies
Preheat the oven to 350°F (180°C). Line a cookie sheet with parchment paper. Slightly oil the paper with coconut oil or oil spray. Set it aside.
Use a small cookie dough scoop to scoop out some cookie dough. Roll the dough between your oiled hands.
Place each ball on the prepared cookie sheet, leaving half a thumb of space between each.
The cookies won’t expand in the oven, but the extra space between them makes it easier to remove them from the sheet once cookes.
Flatten each cookie with your fingertips or the back of a spoon.
Bake the oatmeal cookies for 12 to 15 minutes or until crispy and golden brown on the edges.
Let them cool down on the baking sheet for 10 minutes, then transfer them to a wire rack.
