Maybe the amount is the problem The brownie recipe I used makes 24 two-inch-square brownies and calls for 1T of vanilla (along with 1 cup pecans, 1 1/4 cups cake flour, 1/2 t salt, 3/4t baking powder, 6 oz unsweetened choc, 12 T butter, 2 1/4 cups sugar, 4 eggs--from Cooks Illustrated). Too much vanilla? I don't do sweet-side baking much, so forgive me for being such a doofus.
