Lemon Oatmeal No-Bake Cookies Ingredients
For the Base
• Old-fashioned rolled oats – Provides a hearty texture and is essential for structure in no-bake recipes.

Step‑by‑Step Instructions for Lemon Oatmeal No-Bake Cookies
Step 1: Combine Ingredients
In a large mixing bowl, add 2 cups of old-fashioned rolled oats, ½ cup of natural peanut butter (or almond butter), ¼ cup of maple syrup (or honey), and ¼ cup of melted coconut oil. Then, include the zest of one lemon and the juice from that same lemon. Finally, pour in 1 teaspoon of vanilla extract and a pinch of salt.
Step 2: Mix Thoroughly
Using a spatula or spoon, mix all the ingredients together until they are well combined and form a cohesive mixture. Take care to ensure there are no dry oats left unmixed. The consistency should be sticky but not overly wet, making it easy to shape into cookies. This should take about 2-3 minutes of mixing.
Step 3: Adjust Consistency
If you find that the mixture is too crumbly and not holding together, simply add an additional tablespoon of peanut butter or melted coconut oil. Stir well after adding to ensure the mixture binds together nicely. Aim for a thick, moldable consistency that holds shape when pressed.
Step 4: Shape the Cookies
Once your mixture is ready, use your hands to form small cookie shapes, roughly 1 inch in diameter. Place each formed cookie onto a baking sheet lined with parchment paper, leaving some space between them. The Lemon Oatmeal No-Bake Cookies should be evenly shaped for a uniform appearance.
Step 5: Chill to Set
Now, place the baking sheet into the refrigerator for at least 30 minutes. Chilling allows the cookies to set properly, giving them a firm texture. You’ll know they’re ready when they are firm to the touch and hold their shape well.
Step 6: Serve and Enjoy
After the chilling time is complete, remove the cookies from the refrigerator. They are now ready to be enjoyed! Perfect as a quick snack or a refreshing treat, these Lemon Oatmeal No-Bake Cookies will delight your taste buds with their zesty flavor. Store any leftovers in an airtight container in the fridge for up to a week.
