Favorite Chocolate Fudge Cake

My earliest recorded time to make this was Dec. 1994.  There seems to be an earlier time I wrote that I made it in my cookbook when we had Frams and Hyldahls over, but the date has worn off.  I also made this for Mollie's 2nd (with Fran, Hank, McAllisters and Boones) and 3rd birthdays, Mollie's first communion, Father's Day 2001, once for G+G Miller, Maver and Jerry, for Irene's 16th birthday, and most other birthdays for everyone in between.  I had to give up writing when I made it in the cookbook because the page ran out of room.  This recipe is from Applehood and Mother Pie.
Cake:
4 oz unsweetened chocolate (if you get the premelted, it saves worry and effort)
2 1/2 cups sifted cake flour
2 tsp baking soda
1/2 tsp salt
1/2 cup butter
2 1/4 cups brown sugar
3 large eggs
1 1/2 tsp vanilla
1 cup sour cream
1 cup boiling water

1. Put Crisco in 2 cake pans, and cover bottom and sides.  Sprinkle cocoa in and tap pan to cover crisco.
2. Melt chocolate (if necessary - I do this in the microwave)  Set aside to cool.
3. Sift flour, baking soda and salt into a large bowl.
4. Cream butter in mixing bowl.  Add brown sugar and eggs.  Beat at high speed until light and fluffy, for 5 minutes.
5. Beat in vanilla and chocolate.
6. Stir in dry ingredients alternately with sour cream.
Beat well with a wooden spoon after each addiction, until batter is smooth.
7. Stir in boiling water.  Batter will be thin.
8. Pour at once into prepared pans.  Bake.  350 degrees for about 25-30 minutes.  Put a toothpick in the middle to test - if it comes out clean, it's done.  If it has batter on it, keep baking.  I put the pans onto cookie sheets in case they spill over.
9. Remove from pans.  Cool completely.  Frost with Chocolate Fudge Frosting.

Chocolate Fudge Frosting (addictive as crack)
4 oz unsweetened chocolate
1/2 cup butter (one stick, you sillies)
1 one-pound box confectioner's sugar (powdered - about 4 cups)
1/2 cup milk
1 tsp vanilla

1. Melt chocolate and butter in microwave.  Don't over do it, or it may burn.
2. Combine sugar and milk in a medium-sized metal bowl.  Add chocolate mixture and mix.
3. Set bowl in ice water and beat with a wooden spoon until thickened.  You can put it in a sink full of snow in winter.  Stir in vanilla.
Spread on cooled cake.
