Theresa...I know this a little late, but after reading your post i saw my error in typing out the baking directions. the milk and vanilla need to be added to the base once the first three ingredients are creamed together. that was actually the first time i wrote down the recipe, as i had just created it that night. I'm glad everyone has enjoyed it! i actually have not made it since i first made it and put the recipe on here. i checked to see a while back if anyone had tried it and then forgot i had posted it. i was delighted to see that my recipe was tried and it was so well received!!!
ok so below i corrected the instructions.
