High-Altitude Tip: Ironically, In The High Elevations Of New Mexico, This Cake Cannot Be Successfully Baked In A Loaf Pan Because It Will Not Rise.
You Need To Decrease The Baking Powder To 1 Teaspoon, Increase The Milk By 1 Tablespoon, And Bake The Cake In A 9″ Round Pan If Baking At High Altitude.
