In a large mixing bowl, combine flour, graham cracker crumbs, brown sugar, baking powder, salt and pecans (if desired). In a separate bowl, stir together milk, butter and egg.
Add to the flour mixture and stir well.
Heat a lightly oiled griddle or frying pan over medium high heat.
Pour or scoop the batter onto the griddle, using approximately 1/4 cup for each pancake. Brown on both sides and serve hot.
