How to Make It
Mix the melted butter, brown sugar, and cinnamon together. Place in the refrigerator for 10 minutes.
Prep the pancake batter. Grease a pan.
Scoop the chilled butter cinnamon mixture into a small plastic baggie. Snip the corner to make a makeshift pastry bag.
Over medium heat, add a dollop of pancake batter.
Once bubbles start to form, squeeze a cinnamon swirl into the pancake. Some of it might melt off to the side, but don't panic. This will just cook right into the pancake.
Flip over and cook as usual. Repeat with the rest of the batter.
Heat the rest of the butter (4 tablespoons) and cream cheese in the microwave. About 45 seconds should do the trick, but keep an eye on it. You can also do this in a saucepan over medium heat.
Once melted, mix in the vanilla extract and powdered sugar.
Drizzle on top of each pancake. Serve warm.
