01 - Combine oat flour, protein powder, eggs, almond milk, melted coconut oil, vanilla extract, and a pinch of salt in a blender. Blend until completely smooth, scraping down the sides as needed. Let the batter rest for 5 minutes to allow the flour to hydrate.
02 - In a small bowl, stir together the melted butter, brown sugar, and ground cinnamon until well combined and smooth. Set aside.
03 - Heat a non-stick skillet over medium heat and lightly brush with coconut oil. Pour about ¼ cup of batter into the center of the skillet, tilting and swirling to spread evenly into a thin circle. Cook for 60 to 90 seconds until the edges begin to lift and the bottom is lightly golden. Flip carefully and cook for another 30 to 45 seconds. Transfer to a plate and keep warm. Repeat with the remaining batter.
04 - While the crepes are still warm, spread a thin, even layer of the cinnamon filling over the surface of each crepe. Roll each one up tightly or fold into quarters. Arrange on serving plates.
05 - Whisk together the softened cream cheese, milk, powdered sugar, and vanilla extract in a small bowl until completely smooth and drizzle-able. Add a little more milk if needed to reach the desired consistency.
06 - Drizzle the cream cheese glaze generously over the filled crepes. Serve immediately while warm.
