As someone with a raging sweet tooth, I often make no-bake desserts.

They require minimal preparation and usually few ingredients. While I have a handful of favorites on rotation, nothing beats my famous 3 ingredient no bake oatmeal cookies.

Why I love this recipe

• Wholesome ingredients. Traditional no bake cookies typically contain butter, sugar, and milk, but not these… they taste just as good!
• 3 Ingredients only. All you need are oats, peanut butter, and maple syrup.
• Easy to customize. These cookies act like a blank canvas, so you can fold through your favorite mix-ins, like chocolate chips, coconut flakes, raisins, and more.
• Perfect texture. Thick, chewy, and stable at room temperature. They are naturally sweetened and satisfy the sweet tooth!

Ingredients needed

• Rolled oats. Also called old-fashioned oats, they provide the chewy texture we love in a good oatmeal cookie! You can use quick oats if you like, but it will have a softer texture.
• Peanut butter. Smooth and drippy peanut butter works best, as it is the easiest to mix into the dough. Try to avoid peanut butter with added sugar or ones with a crunchy texture.
• Maple syrup. A refined sugar free sweetener that not only adds sweetness but helps bind the cookies together. You can also use agave nectar or honey.

Step 1- Make the batter. Start by adding your oats into a large mixing bowl. Add the peanut butter and syrup and mix well until combined. Fold through your mix-ins of choice using a rubber spatula.

Step 2- Shape. Next, lightly wet your hands. Form small balls of the cookie mixture and place them on a lined plate. Press down to form a cookie shape and refrigerate them for 20 minutes to firm up.

Arman’s recipe tips

• Use quick cooking oats. Most no bake oatmeal cookie recipes call for these oats as they are softer and smoother in texture.
• Boil the mixture. Sometimes peanut butter can be a little firm, so I like to combine that and the maple syrup in a saucepan and bring it to a boil. Once boiling, add the oats, mix, and shape into drop cookies.
• Add mix-ins. Like any good no bake cookie, be creative by adding in nuts, seeds, chocolate chips, vanilla extract, coconut flakes, or even candy buttons.

Storage instructions

To store: Leftovers should be stored in the refrigerator, covered. They will keep well for up to two weeks.

To freeze: Either wrap cookies individually in parchment paper and place them in a ziplock bag, or place them all together in one ziplock bag (no parchment paper needed). They will keep well frozen for up to 6 months.
