"This is one of my family's favorite coffeecakes. The original recipe called for 3/4 cup evaporate milk with 1 Tbls. lemon juice in it and it was very good. However, using the sour cream and milk makes it even better. It is so moist and tender and delicious you will have to eat seconds! Works well for company or to give as a gift too. I always prepare it on Saturday night for Sunday morning. Just cover lightly with a towel...."
