Step 1

In a medium bowl, combine flour, pie spice, baking powder, baking soda and salt.

Step 2

In a large bowl, whisk melted butter, sweet potatoes, eggs, buttermilk, milk, syrup and vanilla. Add dry ingredients and stir until just combined.

Step 3

Heat a griddle over medium-low heat and grease liberally with butter. Scoop 1/3 cup portions of batter onto the griddle and lightly spread into a circle (the batter will be thick). Cook until set on the bottom, then flip and cook on the other side. Since these pancakes are thick be sure to cook them over low or medium heat; you don't want the outside to burn before the inside is cooked through.

Step 4

Serve pancakes warm with butter, syrup and chopped pecans.
