Oatmeal Cookie Ingredients
Oatmeal banana lovers, this one-serve banana cookie recipe is for you!
All you need to make this large soft oatmeal banana cookie recipe are 3 basic ingredients:
- Ripe banana – The recipe contains no sugar added, so the riper, the sweeter the cookies will be.
- Peanut butter or almond butter, or sunflower seed butter for a nut-free option.
- Rolled oats or quick oats – it depends on the texture you prefer in cookies. Quick oats make the cookies softer, while rolled oats add more chew and texture.
- Protein powder or oat flour – plant-based protein powder adds a great texture to the cookies – you can replace it with oat flour or almond flour. If you skip it, the cookie recipe works, but it will be very soft, and better to eat on a plate.
Optional Add-on And Flavors
You can add any of the below ingredients to boost the cookie flavor and texture:
- Single-serve chocolate chip cookie – add 1-2 tablespoons dark chocolate chips and 1/4 teaspoon vanilla extract.
- Oat raisin flavor – 1-2 tablespoon dried raisins and 1/4 teaspoon ground cinnamon.
- Nutty oatmeal cookie – 1 tablespoon of chopped walnuts or pecans.
- Coconut Cookie – 1-2 tablespoons unsweetened coconut.
- Berry oat flavor – fresh berries like raspberries or blueberries.
Making The Oatmeal Cookie Batter
In a small bowl, mash the ripe banana with a fork until mushy.
Stir in oats, protein powder, and any add-ons you like. For an oatmeal chocolate chip cookie, stir in 1 to 2 tablespoons of chocolate chips.
Stir until it forms a dough ball that is wet and soft but can be gathered into a ball – not liquid.
Baking Or Air-frying
Line a baking sheet or the bottom of the air fryer basket with a piece of parchment paper.
Slightly spray oil on the batter and press down the cookie dough ball into a large single-serve cookie.
Then, sprinkle some extra chocolate chips on top if desired.
Bake or air fry at 350°F (180°C) for about 15 minutes or until golden brown on the sides and crispy on the edges.
Cool it down on a cooling rack for a few minutes to let it steam out.
This is a banana oatmeal cookie recipe with no sugar added and flourless. Therefore they are chewier and softer than regular oatmeal cookies.
For a crispier cookie texture, add 2 tablespoons of granulated sugar to the batter.
This cookie can be stored better in the fridge in an airtight container. You can store it for up to 2 days or freeze it for up to 3 months in zip-lock bags.
You can rewarm the cookie the next day for a few minutes in the air fryer at 300°F (160°C).
Frequently Asked Questions
Can I Make Smaller Cookies?
Yes, you can divide the batter into 6-10 small cookie dough balls.
Roll each ball between your hands and press them down on a baking sheet covered with parchment paper, leaving half a thumb of space between each cookie.
Bake them for 12-15 minutes or until golden brown on the sides.
Can I Add Sweetener?
If your bananas are not ripe enough, you can boost the sweetness of these cookies by adding 1-2 teaspoons of liquid sweetener, like maple syrup, or 1-2 tablespoons of granulated sweetener.
Can I Replace Banana With Something Else?
Yes, you can replace mashed banana with the same amount of homemade pumpkin puree, apple puree, or sweet potato puree.
Can I Skip The Protein Powder?
You can remove the protein powder, but it also adds texture and dries out the cookie batter.
So to avoid a too soft cookie, replace the protein powder with the same amount of oat flour or 1/4 cup of almond flour.
