In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and sea salt until the mixture is uniform and well combined.
In another bowl, blend together the whole milk, large egg, melted unsalted butter, and pure vanilla extract until the mixture is smooth and homogenous.
Carefully pour the wet ingredients into the bowl with the dry ingredients. Gently fold the two mixtures together using a spatula or whisk until just combined. It’s important not to overmix; a few small lumps are perfectly fine.
In a separate small bowl, combine the packed brown sugar and ground cinnamon to create a deliciously sweet cinnamon filling.
Preheat a non-stick skillet or griddle over medium heat. Lightly grease the cooking surface with a bit of melted butter or non-stick cooking spray to prevent sticking.
For each pancake, pour about 1/4 cup of the batter onto the skillet. While the edges are still slightly wet, take about a teaspoon of the cinnamon sugar filling and sprinkle it in a spiral pattern over the pancake batter.
Allow the pancake to cook for about 2-3 minutes, or until bubbles start to form on the surface. With care, flip the pancake and continue cooking for an additional 2 minutes, or until both sides are a lovely golden brown.
Repeat the cooking process with the remaining batter, greasing the skillet as needed to ensure each pancake cooks beautifully.
For the cream cheese drizzle, in a small bowl, combine the softened cream cheese with the pure maple syrup. Mix until it is smooth and creamy; you can add a splash of milk to reach your desired consistency for drizzling.
Serve your fluffy cinnamon roll pancakes warm, generously drizzled with the cream cheese mixture and topped with an extra sprinkle of ground cinnamon, if desired.
