Method:
Preheat oven to 375°F. Line two large baking sheets with parchment paper and set aside.
Put butter and sugar into a bowl and beat with an electric mixer until fluffy. Add egg, vanilla and salt and beat again just until combined. Stir in coconut and sunflower seeds. In a separate bowl, combine oats, flour and baking powder, then add to butter mixture, stirring until thoroughly combined.
Drop rounded tablespoons of dough onto prepared baking sheets, spacing them about 2 inches apart. Bake until lightly browned and cooked through, 10 to 12 minutes, then set aside to let cool. Serve immediately or store in an airtight container.
