I purchased this to make my own shortbread cookies in a jar and give them away for the holidays.  I have to admit, I was neverous about using a powdered vanilla and even more neverous about how my gift jars would turn out with this product.  I put my jars together, test baked and they turned out perfect.  I can't tell you if this product flavor weakens with time as it is a concern when I am making cookies or brownies in a jar for gifts.
