In a large mixing bowl, add 2 cups of old-fashioned rolled oats, 1 cup of natural peanut butter, 1/2 cup of maple syrup (or honey), and 1/4 cup of melted coconut oil. Pour in the zest of 2 lemons, 1/4 cup of fresh lemon juice, 1 teaspoon of vanilla extract, and a pinch of salt. Stir everything together thoroughly until a sticky dough forms, taking about 2-3 minutes.

If your mixture feels too crumbly or dry, add an extra tablespoon of peanut butter or melted coconut oil. Incorporate it well by mixing for another minute until the dough is smooth and holds together nicely.

Using a tablespoon, scoop out portions of the dough and roll them into small balls. Gently flatten each ball slightly to create a thick disc shape. Aim for a consistency that can be easily formed into balls.

Line a baking sheet with parchment paper and place the formed cookies on it, ensuring they're spaced apart. Chill for about 30 minutes or until the cookies are firm enough to hold their shape.

Once chilled, store any leftovers in an airtight container. They will stay fresh in the refrigerator for up to 7 days.
