Add Wet Ingredients: Stir in the melted butter, honey, egg, and vanilla extract until well combined.
4 Tablespoons unsalted butter, ¼ cup honey, 1 large egg, 1 teaspoon vanilla extract
Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, salt, and rolled oats.
½ cup all-purpose flour, 1 tsp baking soda, 2 3/4 cups rolled oats, 1/2 teaspoon salt
Combine Wet and Dry: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Fold in the semi-sweet chocolate chips and walnuts, if using.

Scoop and Shape: Use a medium cookie scoop or drop 2 tablespoons spoonfuls of dough onto the prepared baking sheet, flatten them into disks. Spacing them about 2 inches apart.
Bake: Bake for 8-10 minutes, or until the edges are lightly golden and the cookies are set. Do not overbake or they will dry out. Note: though dough is a little sticky, feel free to get your hands a little wet to help from sticking onto your hands.
Cool: Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
