Here it is - sorry it took me a bit to find it.
This recipe did not have cranberries in it, but would be easy enough to add. I’d start with 1/2 chopped fresh cranberries or 1/2 c cranraisins. You might want to add an extra 1/4 c sugar with the fresh cranberries if you like your muffins on the sweet side.

Orange Pecan (Cranberry) Muffins

1/2 c butter or margarine softened
1 c sugar
2 eggs
1 c vanilla yogurt
2 c all purpose flour
1 tsp baking soda
3/4 cup pecans, toasted
1 tsp grated orange peel

Topping:
1/4 c orange juice
1 T sugar

In a mixing bowl, cream butter and sugar. Beat in eggs and yogurt. Combine flour and baking soda; stir into the creamed mixture just until moistened. Fold in pecans and orange peel (and cranberries). Fill paper lined muffin cups 3/4 full. Bake at 375 for 18-20 minutes until a toothpick comes out clean. Brush or spritz orange juice over hot muffins and sprinkle with sugar. Cool 5 minutes before removing to a wire rack. Make 12-15 muffins.
