I purchased some Bols Blue, a liquor with citrus in it made in Holland. Using this in baked goods is done so everyone can eat. I folded half of the white chocolate pudding in the batter and of course it is blue. This liquor is also good with Sprite soft drink. I wanted something special for our anniversary. It is a rich dessert. I just made this cake again but refrigerated it overnight and it makes a big difference in the flavor, moist & flavor seems to be more intense.
