Mix butter, brown sugar, and cinnamon together, heating it up in the microwave to get it pourable consistency if you need to. You don’t want the butter completely melted or it will come out of your squirt bottle (or pastry bag) too quickly and you won’t get a pretty swirl.

Add pancake batter to your pan as normal and quickly make a swirl of the cinnamon sugar mixture. Cook the pancake until bubbles form on top and then flip.
