I'm not sure where you draw the line between breakfast and dessert, but this is worth making for both.
Adapted from Better Homes and Garden
2 1/2 cups flour
1 1/2 cups packed brown sugar
1/2 teaspoon salt
2/3 cup butter, margarine, or shortening
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon cinnamon
1/4 teaspoon nutmeg
1 1/3 cups buttermilk (or substitute sour milk)
1/2 cup chopped nuts (I used pecans)
Grease bottom and sides of a 13x9-inch baking pan.
In a large bowl combine flour, brown sugar, and salt. Cut in butter until mixture resembles coarse crumbs; set aside 1/2 cup. Stir in baking powder, baking soda, cinnamon and nutmeg into remaining crumb mixture. Add eggs and buttermilk. Pour into prepared pan. Combine reserved crumb mixture and nuts; sprinkle over batter.
Bake at 350 degrees for 35 minutes or until toothpick comes out clean. Serve warm.
