Wondering if you dusted those white chips with flour before mixing them in the batter if they would sink to the bottom? Honestly, I've had disastrous results converting from milk chocolate to white chocolate too. I'm reluctant to try it after I've flubbed with white chocolate in the past! LOL
I had to come back to this thread for this recipe so I can take this cake to the river to tailgate in two weeks. Be still my beating heart! I can NOT wait!
