Preheat the oven to 350°F (175°C).

In a mixing bowl, combine the flour, oats, baking soda, salt, and cinnamon.

In another bowl, cream the softened butter and honey together until smooth.

Add the egg and vanilla extract to the butter mixture and mix well.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Fold in chocolate chips and/or nuts if using.

Drop spoonfuls of dough onto a baking sheet lined with parchment paper.

Bake in the preheated oven for 10-12 minutes or until the edges are golden.

Remove from the oven and let cool on the baking sheet for a few minutes before transferring to a wire rack.
