Preheat the oven to 375°F (190°C) and apply non-stick cooking spray to 8 wells of a standard muffin tin.
In a medium mixing bowl, combine the high-protein pancake mix, almond milk, and liquid egg whites. Whisk until the batter is smooth and free of large lumps.
Fold the pre-cooked crumbled turkey sausage, maple syrup, and maple extract into the batter until evenly incorporated.
Distribute the mixture evenly into the 8 prepared muffin wells, ensuring even volume for consistent baking.
Transfer to the center rack of the oven and bake for 12 to 15 minutes, or until the internal structure is set and the tops are golden brown.
Remove from the oven and allow the bites to rest in the tin for 3 minutes to facilitate easy release before serving.
