Begin by making the Bourbon Maple Cream Cheese Syrup: In a small bowl, mix together the butter, cream cheese, maple syrup, and bourbon. Sift in the powdered sugar, and stir until combined.
Next, in a small skillet on low heat, toast the pecans until they're lightly toasted, about five minutes.
Next, make the pancake batter: In a large bowl, sift together the flour, baking powder, salt and sugar.
In a second smaller bowl, beat together the egg, eggnog, and sour cream. Then stir this mixture into the flour mixture. Mix just until no streaks remain. Stir in the melted butter.
Heat a nonstick skillet on medium heat and melt a teaspoon of butter. Ladle about a quarter cup of batter on the skillet. When bubbles appear, flip your pancake, and cook the second side.
Add more butter, as necessary to cook the rest of the pancakes. Top the pancakes with the toasted pecans and the Bourbon Maple Cream Cheese Syrup.
