Preheat oven to 350F. In 9 x 9 inch glass Pyrex dish, break bread into medium-sized pieces.
Beat milk, sugar, egg yolks, cinnamon, vanilla, butternut vanilla, butter and pecans together in a large bowl. Mix well. Pour over bread. Liquid mixture should cover top of bread. Bake at 350F for about 45 minutes or longer for firm pudding; less time for softer pudding.
