Filling
- In a medium bowl, mix softened butter, brown sugar, and cinnamon in a small bowl. Transfer to a piping bag or zip-top bag and snip a small corner.
Icing
- Whisk together powdered sugar, cream cheese, milk, vanilla, and salt until smooth. Set aside.
Pancakes
- In a bowl, whisk flour, sugar, baking powder, baking soda, and salt.
- In another bowl, whisk milk, sour cream egg, oil (or melted butter) and vanilla.
- Combine wet and dry just until mixed (don’t overmix).
- Heat a pan over medium low heat, lightly butter it, and pour about ¼ cup batter for each pancake. When bubbles form on top, pipe a spiral of cinnamon swirl onto the pancake. Cover with lid and let steam 5-6 minutes. Repeat until batter is gone.
- Stack warm pancakes, then drizzle generously with cream cheese icing.
