Preheat your oven to 350°F (175°C) and line a sheet pan with parchment paper or lightly grease it with coconut oil.
In a large mixing bowl, whisk together the almond flour, tapioca starch, whey protein powder, baking powder, and salt until well combined.
In a separate bowl, whisk together the melted coconut oil, dairy-free milk, and eggs. If using, add the maple syrup to the wet ingredients.
Pour the wet ingredients into the dry ingredients and stir until just combined. The batter should be smooth and slightly thick.
