Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.

Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.

In a separate bowl, whisk together the flour, baking powder, baking soda, cinnamon, and salt.

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

Fold in the oats, chocolate chips, shredded coconut, and chopped nuts.

Using a cookie scoop or tablespoon, drop dough balls onto the prepared baking sheets, leaving about 2 inches between each.

Bake for 10–12 minutes or until the edges are golden and the centers look just set.

Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
