MAKE THE GLAZE: Beat cream cheese until smooth. Add maple syrup and vanilla bean paste and mix until combined. Add a splash of heavy cream or milk if you want a thinner, drizzleable consistency. Set aside.
MAKE THE PANCAKES: In a large bowl, whisk together the flour, brown sugar, baking powder, baking soda, cinnamon, ginger, nutmeg, and salt.
In a separate bowl, whisk together the buttermilk, egg, melted butter, and vanilla extract.
Pour the wet ingredients into the dry and stir until just combined — do not overmix. Fold in the grated carrots and walnuts.
Heat a non-stick skillet or griddle over medium heat and add butter or neutral oil. Pour about ½ cup of batter per pancake. Cook until bubbles form on the surface and the edges look set, about 2-3 minutes. Flip and cook 1-2 minutes more.
Serve warm topped with maple cream cheese glaze.
