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. Allow the batter to rest for 5 minutes so the flour fully hydrates.
02 - In a small bowl, stir together the melted butter, brown sugar, and ground cinnamon until a smooth, spreadable paste forms. 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 pan, tilting and swirling immediately to spread it into an even, thin layer.
04 - Cook for 60 to 90 seconds until the edges begin to lift and the bottom turns lightly golden. Carefully flip with a spatula and cook for another 30 to 45 seconds. Transfer to a warm plate and repeat with the remaining batter.
05 - While the crepes are still warm, spread a thin, even layer of the cinnamon filling across the surface of each one. Roll them up tightly or fold into quarters.
06 - Whisk together the softened cream cheese, milk, powdered sugar, and vanilla extract in a small bowl until completely smooth and drizzle-able. Add additional milk, a splash at a time, if a thinner consistency is desired.
07 - Arrange the filled crepes on serving plates and drizzle generously with the cream cheese glaze. Serve immediately while warm.
