Mix Bisquick mix, buttermilk and eggs in a bowl until lumps are gone.
In a separate bowl combine melted butter, brown sugar, and cinnamon. Stir till smooth, and spoon into a zip close bag.
Heat a skillet over medium-low heat. Spray with nonstick spray. Scoop about 3/4 cup batter onto the skillet. Snip the corner of your baggie of filling and squeeze a spiral of the filling onto the top of the pancake. When bubbles begin to appear on the surface, flip carefully with a spatula, and cook until browned on the underside, 1 to 2 minutes more.
For the glaze add the cream cheese and butter to a microwave safe bowl and heat until melted. Whisk till smooth and add powdered sugar and vanilla, whisking again till smooth.
Pour glaze on top of a pile of cinnamon pancakes, let your inner child take over and dig in!
