Sift the flour, baking powder, salt and sugar together. Stir in the 1 cup of oats. Cut in the butter or margarine with a pastry blender. Combine the eggs and milk and add to the dry ingredients, mixing lightly with a fork. Mix only until the ingredients are moistened. Half fill 12- well-greased muffin pan cups. Mix the melted butter or margarine with the ¼ cup of oats. Sprinkle evenly over the muffins. Bake at 400 degrees F for 20-25 minutes.

(When ready for the oven, these muffins may be covered with waxed paper and stored in the refrigerator overnight, to be baked the following morning.)
