Preheat your oven to 325.
Line a baking sheet with parchment paper or a silicon baking mat.
In one bowl mix together your dry ingredients (oats, flour, baking powder, salt, cinnamon).
In another bowl mix together your wet ingredients (melted oil/butter, egg, vanilla, agave).
Pour your wet ingredients into your dry ingredients and mix until just combined.
Fold in your diced apples until they are just incorporated.
Chill the dough in the fridge for about 30-45 minutes to firm up a bit
Drop tablespoon size balls onto your baking sheet and flatten slightly (these will not spread much at all once in the oven).
Bake for 12-13 minutes. Don’t over bake or they will come out too dry. So just when they are set remove from oven and let cool for about 10 minutes.
