In another bowl, whisk together buttermilk, eggs, and maple syrup.
1 3/4 cups buttermilk, 2 eggs, 2 tablespoons maple syrup
Make a well in the center of the dry ingredients and pour in the buttermilk mixture. Stir until just blended; a few lumps is OK. Fold in the pecans. Let batter rest while you preheat the griddle to medium/350°F.
1 cup chopped pecans
Once the griddle is hot, stir the melted butter into the batter. Pour batter onto griddle using a small measuring cup. Cook until bubbles start to form on top and edges look dry, then flip and cook the other side until golden. Repeat with remaining batter.
4 tablespoons butter
Notes
If batter is too thick, stir in an additional ¼ cup buttermilk.
If pancakes are browning too quickly, turn heat down to 325°F.
