Preheat oven to 180 degrees Celsius (fan forced). In a blender combine the oats and process until a meal forms.
Transfer oatmeal into a medium mixing bowl. Add in protein powder, baking powder, nut butter, cinnamon, maple/honey, and milk or calcium-fortified plant alternative.
Mixing with a spatula until well combined and then transfer mixture into a lined sheet pan, spreading across the base of the on to evenly distribute. Place chopped pecan pieces on top.
Place in the oven and bake for ~15 minutes or until firm to touch.
Slice up into ~6 bars and serve warm (or microwaved for ~1 minutes the next morning) with serving suggestions.
Store in the refrigerator.
