When my ex-mother-in-law makes this, she is very particular about how the ingredients are mixed. Being a next generation chef, I don't really give a shit, and E says the cake kicks ass.
2 sticks butter, softened
3 cups sugar
1 cup sour cream
3 cups flour
1/2 tsp baking soda
2 tsp vanilla
Add flour and baking soda after all wet ingredients to avoid over mixing the batter. This produces a batter that does not get tough when baked.
Fold in the vanilla last. Just because I said so.
Preheat oven to 325 degrees F.
Grease and flour tube pan.
Batter is very thick and will need to be spread evenish on top. Do not bang the cake pan on the counter to level it.
Bake 1 hour 20 minutes or until toothpick inserted in center comes out clean. Let cake rest in pan about 10 mins before removing.
Glaze with confectioner's suger glaze after cooling completely.
Mmmm, mmmm good...
