Preheat oven to 375°F (190°C) and grease a standard 12-cup muffin tin.
Whisk together the pancake mix, protein isolate, and cinnamon in a large mixing bowl.
In a separate bowl, whisk the water, egg, and maple syrup.
Combine wet and dry ingredients, stirring until just incorporated.
Gently fold the bacon bits into the batter.
Portion the batter into the prepared muffin tin, filling each cup approximately two-thirds full.
Bake for 14 to 16 minutes until a toothpick inserted into the center comes out clean.
Allow muffins to rest in the tin for 5 minutes before transferring to a cooling rack.
