Prepare the cinnamon filling: In a medium bowl, stir together the butter, brown sugar and cinnamon. Scoop the filling into a squeeze bottle, piping bag or a zip baggie. Set it aside at room temperature.

Prepare the glaze: In a microwavable bowl, melt the butter. Whisk in the cream cheese until it is almost smooth. Sift the powdered sugar into the pan, stir and add in vanilla extract. Set the pan aside while you make the pancakes.

Prepare the pancake batter: In a medium bowl, whisk together the flour, baking powder and salt. Whisk in the milk, egg and oil, just until the batter is moistened (a few small lumps are fine).

Cook the pancakes: Heat a large, nonstick pan over medium-heat and brush it with butter.

Use a spoon to scoop the batter to the pan. Let the batter spread out naturally into a circle

When your pancake begins to form bubbles, add the filling. Starting at the center of the pancake, squeeze the filling on top of the pancake batter in a swirl (just as you see in a regular cinnamon roll). Cook the pancake 2 to 3 minutes, or until the bubbles begin popping on top of the pancake and it's golden brown on the bottom. Slide a thin, wide metal spatula underneath the pancake and gently but quickly flip it over. Cook an additional 2 to 3 minutes, until the other side is golden as well.

When you flip the pancake onto a plate, you will see that the cinnamon filling has created a crater-swirl of cinnamon. Wipe out the pan with a paper towel, and repeat with the remaining pancake batter and cinnamon filling. Re-warm the glaze briefly, if needed. Serve pancakes topped with a drizzle of glaze.
