Add rolled oats, protein powder, baking soda, baking powder and cinnamon to a large bowl and mix until combined.
Add applesauce and melted almond butter. Mix the almond butter into the applesauce to ensure it doesn't harden and clump.
Add remaining wet ingredients and stir until just combined, then fold in blueberries.
Scoop oatmeal mixture into jumbo muffin molds on top of baking sheet. Top with almond slivers.
Bake at 350 degrees for 35 minutes or until the tops begin to get golden brown and do not collapse when touched (they will get firmer as they cool).
