Sauté the apples. Melt 2 tablespoons butter in a skillet over medium heat. Add the diced apples, a pinch of salt, cinnamon, orange zest, and brown sugar. Stir to coat.
Reduce the glaze. Add the apple liqueur, if using, and cook, stirring occasionally, until the liquid reduces to a thick glaze and the apples are tender but still have a little bite, about 8–10 minutes. Transfer to a bowl and set aside. The glaze will thicken as it cools.
Mix the dry ingredients. In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. Make a well in the center and set aside.
Mix the wet ingredients. In a separate bowl, whisk together the milk, oil, apple cider vinegar, vanilla, sour cream, and eggs until smooth.
Make the batter. Pour the wet ingredients into the dry ingredients and stir. Add ⅓ cup apple butter and gently mix until just combined. A few lumps are fine; do not overmix. Let the batter rest for about 5 minutes while the griddle heats.
Heat the griddle. Preheat the griddle to about 350–375°F. Add about ½ to 1 tablespoon of butter or oil to very lightly lubricate the griddle. Spread it around with your spatula.
Make the cream cheese drizzle. With a hand mixer, beat together the melted butter, softened cream cheese, powdered sugar, and vanilla until smooth. Add milk 1 tablespoon at a time if needed to reach a drizzling consistency. Transfer to a zip-top bag and set aside.
Cook the pancakes. Scoop about ¼ cup of batter onto the griddle for each pancake, leaving room to flip. Cook until bubbles and air pockets form on top and the bottoms are golden, about 3–4 minutes. Flip and cook until cooked through, about 2 minutes more.
Cool slightly. Transfer the pancakes to a plate and let them cool for a couple of minutes so the drizzle doesn't melt and run off.
Top and serve. Spoon the cinnamon apples over the pancakes. You can also stack the pancakes with a thin spread of extra apple butter in between, and then top the stack with the apples. Then snip a small corner from the zip-top bag and drizzle with the cream cheese glaze. Sprinkle with chopped nuts, if using, and finish with a spoonful of syrup from the apples. Serve warm.
