Cattail Banana Muffins

1 cups all-purpose flour
1 cup cattail pollen
3 tablespoons buttermilk
1 tablespoon baking powder
1 teaspoon salt
¼ teaspoon baking soda
½ cup butter, softened
2 tablespoons vegetable oil
1 cup honey
2 eggs
1 ½ cups mashed ripe bananas
½ cup chopped walnuts

1. Heat the oven to 350° (175°C). Grease and flour a 12-cup muffin tin or line with paper liners.
2. Combine the dry ingredients: flour, cattail pollen, buttermilk, baking powder, salt and baking soda in a medium bowl; make a well in the center.
3. In separate bowl, cream butter, oil and honey. Add eggs, beating thoroughly. Mix in banana. Pour mixture into well. Mix batter until just moistened; do not over mix. Gently fold in walnuts. If the mixture is too dry, add a little milk.
