Preheat your oven to 350°F and grease a 9x13-inch baking dish. Set it aside.
In a large mixing bowl, combine the Kodiak Cakes pancake mix, butter, baking powder, Splenda, and water. Stir them together until just mixed. Make sure not to overmix; a few lumps are okay.
Pour the pancake batter into the greased baking dish, spreading it out evenly.
In a small bowl, mix the whipped cream cheese and cinnamon until well combined.
Carefully spoon small dollops of the cream cheese mixture over the top of the pancake batter.
Use a knife or skewer to gently swirl the cream cheese mixture into the pancake batter to create a marbled effect. Be careful not to overmix; you want distinct swirls.
Bake in the preheated oven for 20-25 minutes, or until the pancake bake is golden brown and cooked through. You can check for doneness by inserting a toothpick or cake tester into the center – it should come out clean when the bake is done.
Once done, remove the cinnamon roll pancake bake from the oven and let it cool for a few minutes.
Slice the bake into squares or rectangles, just like cinnamon rolls.
Serve your Cinnamon Roll Pancake Bake warm. You can top it with additional cream cheese, a drizzle of maple syrup, or a dusting of powdered sugar for extra flavor.
