Streusel-filled Coffee Cake

This DELICIOUS cinnamon-tasting cake is great with hot coffee and believe it or not, from an old Betty Crocker cookbook!

CAKE:
1 1/2 cups flour (if using self-rising flour, omit baking powder and salt)
3/4 cup sugar
2 1/2 teaspoons baking powder
3/4 teaspoon salt
1/4 cup butter (1/2 stick)
3/4 cup milk
1 egg

TOPPING:
1/2 cup brown sugar (packed)
2 teaspoons cinnamon
1/2 cup finely chopped nuts
2 tablespoons butter (melted)
