How to make make 3 ingredient oatmeal cookies

Essentially, you really only need three ingredients for this cookie recipe: bananas, oatmeal, and ground flaxseed. You can stop right there if you’d like!

Personally, I love to add vegan chocolate chips, vanilla extract, and a dash of salt to enhance the flavor. Here’s my recommended ingredients list for these banana oatmeal cookies:

  • Bananas: Bananas provide a soft and chewy texture, as well as several nutrients. They contain vitamin B6, manganese, vitamin C, copper, potassium, and magnesium.
  • Oats: This flourless cookie recipe uses oats instead of flour. Rolled oats are a whole grain and packed with fiber.
  • Ground flaxseed: Ground flaxseed provides various health benefits and contains antioxidants, lignans, and omega-3 fatty acids.
  • Chocolate chips: Feel free to use any chocolate! If you want to keep the recipe low in sugar, opt for dark chocolate chips or sugar-free chocolate chips.
  • Vanilla: In my opinion, cookies aren’t complete without a spoonful of vanilla extract.
  • Salt: Just a dash of salt is needed to balance the sweetness of the overripe bananas.

Kaylie’s tips for making banana oatmeal cookies

Use overripe bananas. Be sure your bananas are overripe or, at the very least, ripe enough! Ripe bananas have a yellow peel with brown specks all over it. Overripe bananas will have a peel that is equal parts brown and yellow. The riper your bananas, the sweeter your cookies will be! Do not use bananas with a solid yellow peel; wait a few days for them to ripen.

How to substitute ground flaxseed: If you don’t have any ground flaxseed at home, you can replace it with an additional 1/4 cup rolled oats or 1/4 cup oat flour. For double chocolate cookies, use 3 tbsp cocoa powder instead.

Mix-ins for oatmeal cookies

Not a fan of chocolate chips? No problem! There are several options for mix-ins besides chocolate. You can add raisins, crushed walnuts, crushed pecans, coconut flakes, shredded coconut, pumpkin seeds, cacao nibs, and dried cranberries instead.

Should these be stored in the refrigerator?

If you plan to enjoy the whole batch within one day, they’ll be fine in an airtight container on your countertop. However, if storing for longer, the cookies will remain fresh for up to 5 days in the refrigerator. To reheat, pop them in the microwave for 15 seconds.

Are these cookies freezer-friendly?

One of the best things about these banana oatmeal cookies are the fact that they’re freezer-friendly! You can double or triple the recipe and store them in the freezer for longterm snacking. The cookies will keep for up to one month in an airtight container in the freezer.
