Gramio's Mace Cake

This is my Gramio's Mace Cake Recipe.

This is the cake I grew up with and always looked forward to when we went to visit my grandmothers house.  It is a luscious heavy velvety pound cake with an absolutely delightful crust when done correctly. Bake at 375 for thirty minutes reduce heat to 350 bake for another thirty minutes or until done.

2 teaspoons of vanilla

Mace to taste.
