01 - Preheat oven to 350°F (175°C). Grease a 9x13-inch baking dish thoroughly to prevent sticking.
02 - In a large mixing bowl, whisk together all-purpose flour, granulated sugar, baking powder, baking soda, and salt until evenly blended.
03 - In a separate bowl, whisk eggs, buttermilk, melted butter, and vanilla extract. Ensure the mixture is smooth and homogeneous.
04 - Pour wet ingredients into the bowl of dry ingredients and gently fold until just combined; avoid overmixing to preserve texture.
05 - Spread pancake batter evenly into the prepared baking dish. In a small bowl, mix melted butter, packed light brown sugar, and ground cinnamon. Drizzle and swirl cinnamon mixture over the batter using a spoon.
06 - Place baking dish in the oven and bake for 28–32 minutes, until the surface is golden and a toothpick inserted in the center emerges clean.
07 - While the bake cooks, blend softened cream cheese with powdered sugar, milk, and vanilla extract using an electric mixer or hand mixer until a creamy, pourable consistency is achieved.
08 - Remove dish from oven and let cool for 5–10 minutes. Drizzle cream cheese glaze evenly over the warm bake. Slice and serve immediately.
