Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

In a medium bowl, whisk together the instant oats, whole wheat flour, baking powder, ground cinnamon, and salt.

In a large bowl, mix the melted coconut oil, large egg, vanilla extract, and agave syrup until fully combined.

Gradually add the dry ingredient mixture to the wet ingredients, stirring until just combined.

Gently fold in finely diced red apples into the cookie dough.

Using a cookie scoop or tablespoon, drop rounded scoops of cookie dough onto the prepared baking sheet, spacing them about 2 inches apart.

Place the baking sheet in the preheated oven and bake for 10-12 minutes.

Once baked, remove the cookies from the oven and cool on the baking sheet for 5 minutes before transferring to a wire rack.

For an optional glaze, combine powdered sugar with a splash of vanilla extract and water to achieve a smooth consistency.
