Note: The top 6 muffins have streusel: to make streusel you need
1/4 brown sugar
1/2 teaspoon ground cinnamon
1 tablespoon cold butter or margarine
1/4 cup finely ground nuts (I like walnuts with these)
Combine brown sugar and cinnamon, cut in butter until it resembles coarse crumbs. Sprinkle on over batter and bake.
