How to Make 4 Ingredient Oatmeal Raisin Cookies

To help make your raisins softer and plumper, you can opt to soak them in water overnight to rehydrate but this is not necessary for wonderful cookies.

  1. Preheat your oven to 375 degrees.
  2. Mash your banana.
  3. Mix together your mashed banana, oats, cinnamon and raisins.
  4. Spoon your dough onto a parchment-lined cookie sheet and press flat with a fork.
  5. Bake for 8 to 10 minutes until the edges have turned golden.

Helpful Eazy Tip: When pressing down the cookies with the fork, it helps to dip the fork into a bowl of water so that the cookie dough won’t stick to the fork.

Suggestions for Putting a Twist on the Recipe

Making these cookie treats is very easy, in fact, almost as easy as my 2 Ingredient Chocolate Banana Muffin Top cookies.

You can add any dried fruit in addition to the raisins. Try including dried cherries or cranberries. (cut back on the raisins and replace the amount with the berries).

Increase the protein by adding some chopped nuts or try adding some fiber with dried coconut. These are a great way to add clean ingredient treats to your family’s diet.

Try adding chocolate chips or diced leftover Halloween candy for a fun treat that resembles more traditional cookies while still drastically reducing the refined sugar and keeping them easy to make.

How to Serve these Treats

Serving them just as a healthy snack for your family anytime anyone feels a little hungry is perfect. Just like my 4 Ingredient Banana Chocolate Chunk cookies, I like serve them an ice cold glass of milk with these oatmeal cookies. The combination of milk and cookies is unbeatable.

Pop them in the kid’s lunches for school or give them a few for an afterschool snack that you know is a healthy treat for them.

These make a great addition to party platters, snack trays, and holiday cookie boards. No one will even notice that you brought something relatively healthy mixed in with all of the sugar-filled treats.

Keeping the Cookies Fresh

This is pretty easy to do by storing them in an air-tight container so they don’t harden. They’ll last a few days at room temperature this way. However, keep in mind because they don’t have a lot of sugar to extend their freshness, and there’s fresh banana in the recipe, there is a certain amount of moisture included. So if you want to keep them a bit longer, it’s a good idea to keep them refrigerated.

If you need to keep them longer, consider storing them in the freezer for up to three months if you plan to make them ahead to always have some on hand.

The ripeness and size of your bananas will depend on how moist the cookie dough sticks together. Adding a few tablespoons of water will assist in helping everything come together if the bananas were a bit small.

If you want to add extra 'add-ins', reduce the amount of raisins and add the same amount in dried fruit. If adding coconut, there's no need to adjust the raisins as coconut is light and won't weigh down the dough.

This recipe makes bite-size cookies so if you want to make them bigger, your yield will be cut down.
