In a large mixing bowl, whisk together the flour, baking powder, salt, and granulated sugar. In another bowl, beat together eggs, milk, and vanilla extract until well combined. Add the melted butter to the wet ingredients and mix well.
Pour the wet mixture into the dry ingredients. Gently stir until just combined. The batter should be lumpy but not overmixed. Let it sit for a few minutes to thicken.
In a small bowl, combine the brown sugar and ground cinnamon. Set aside.
Preheat a large non-stick skillet or griddle over medium heat. Pour about 1/2 cup of pancake batter onto the skillet for each pancake. Use the back of a spoon to spread it out slightly into a larger circle.
Before the batter sets, sprinkle a portion of the cinnamon-sugar mixture in a spiral pattern over the pancake. Use a toothpick or a skewer to gently swirl the cinnamon mixture into the pancake. Cook for about 3-4 minutes or until bubbles form on the surface.
Carefully flip the pancake and cook for an additional 3-4 minutes or until golden brown and cooked through. Repeat this process for the remaining batter.
While the pancakes are cooking, combine the softened cream cheese and powdered sugar in a bowl. Add 1-2 tablespoons of milk and mix until smooth and pourable. If needed, adjust the consistency by adding more milk.
Stack the giant cinnamon roll pancakes on a plate and drizzle with the cream cheese glaze. Optionally, sprinkle some additional cinnamon-sugar mixture on top for garnish.
Notes
Serve these giant pancakes stacked high on a nice plate, with a drizzle of glaze cascading down the sides and a sprinkle of cinnamon on top. Add fresh fruit or a dollop of whipped cream for additional color and richness.
