Preheat your oven to 350°F (175°C) to ensure even baking.
Line a baking sheet with parchment paper to prevent sticking.
In a large mixing bowl, whisk together the all-purpose flour, whole wheat flour, oats, baking powder, baking soda, and salt until well combined.
In another bowl, beat the butter and brown sugar together until light and fluffy, about 2-3 minutes.
Add the honey, vanilla extract, egg, and egg white to the butter and sugar mixture, mixing until fully incorporated.
Gradually add the dry mixture to the wet mixture, stirring until just combined.
Gently fold in the chocolate-covered sunflower seeds, ensuring an even distribution throughout the dough.
Using a cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheet, leaving space between each cookie.
Bake for about 10-12 minutes, until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
