Preheat the oven to 350°F (175°C) and line a baking tray with parchment paper.
In a large bowl, combine the rolled oats, whole wheat flour, The Holly Tree Organic Ginger Powder, The Holly Tree Organic Cinnamon Powder, The Holly Tree Organic Nutmeg Powder, Salt, and baking powder.
In a separate bowl, whisk together the melted coconut oil (or butter), honey, egg, and vanilla extract.
Pour the wet ingredients into the dry ingredients and mix until a soft cookie dough forms.
Scoop tablespoon-sized portions onto the prepared baking tray, leaving space between each cookie. Gently flatten each cookie with the back of a spoon.
Bake for 12–15 minutes, or until the edges are lightly golden.
Allow the cookies to cool on the baking tray for 5 minutes before transferring them to a wire rack.
Finish with a light dusting of The Holly Tree Organic Ginger Powder and The Holly Tree Organic Cinnamon Powder before serving.
