Quick Orange and Lemon Cake

Another cake my mom and I found somewhere.

1 lemon
1 orange
1 1/4 cup self-rising flour
1 tsp baking powder
1 cup + 2 T sugar
1 stick butter, softened
2 eggs
3 T milk

Preheat the oven to 350F and line a 7-inch round cake pan with waxed paper, lightly greased with butter.  Grate the peel of the lemon and orange, then cut each in half and squeeze the juice from half of each.  Combine the juices in a bowl.  Place all ingredients except the orange and lemon juice and 1/4 cup sugar in a blender and mix thoroughly.  Pour the batter into the prepared pan and bake for 40-50 minutes.  Remove from oven and leave in the pan.  While still hot, sprinkle the top with reserved sugar.  Then drizzle the mixture of lemon and orange juice over it.  Makes 6-8 servings.
