Banana Macadamia Nut Muffins

1 cup mashed banana (2 to 3 medium)
1/2 cup vegetable oil
1/3 cup milk
1/3 cup chopped macadamia nuts (or walnuts or pecans)
1 egg
1 cup whole wheat flour
1 cup white flour
1/3 cup packed brown sugar
1 tablespoon baking powder
1/2 teaspoon salt

Heat oven to 400. Grease muffin cups, or line with paper baking cups.

Beat mashed banana, oil, milk, nuts, and egg with a spoon in a medium bowl.

Stir in remaining ingredients just until moistened (batter will be lumpy, so don’t be tempted to overbeat).

Spoon batter into muffin pan.

Bake about 20 minutes at 400, just until golden brown. Immediately remove from cups.
