This is a fabulous recipe!!!! I found this at eclectic cook.
1 cup whole wheat flour
1 cup all-purpose flour
1 teaspoon baking powder
1 teaspoon baking soda
1/4 teaspoon salt
2 teaspoons cinnamon
1 teaspoon nutmeg
1/2 cup unsalted butter, softened
1/2 cup sugar
1/4 cup packed brown sugar
1 large egg, lightly beaten
1 cup buttermilk, room temperature
1 1/2 cups green tomatoes, seeded and chopped
brown sugar for sprinkling
Preheat oven to 450 degrees F. Greas and flour muffin tin or line with paper cups. In a medium bowl, mix the flours, baking powder, baking soda, salt, cinnamon and nutmeg. In a large bowl, cream together the butter and sugars. Add the egg and mix well to combine. Gently stir in the buttermilk. Stir in the flour mixture and fold in the tomatoes. Fill the muffin cups with the batter. Generously sprinkle the muffins with brown sugar. Bake for 10 minutes and then lower the oven temperature to 400 degrees F. Bake for 15 to 20 minutes more. Muffins should be golden brown and a cake tester or toothpick inserted in the center of a muffin will come out clean. Cool for 10 minutes, then remove from tin and cool completely on a wire cooling rack.
