Preheat oven to 350. Grease a 12 muffin cup tin. Be sure and spray very generously, if you don't, they will stick. Using Bakers Joy always works for me.
In a bowl, stir brown sugar, flour and pecans together. In a separate bowl, beat together the butter and eggs. Stir the wet mixture into the dry ingredients and combine.
Fill each muffin cup ⅔ full. Bake for 15-17 minutes. Take a knife and run it around the edge of each muffin before removing.
