    This recipe makes a moist,delicious cake!(I followed the directions exactly and submitted the picture.) There are a few tips I can offer: 1)I recommend a heavy duty mixer, not a light or hand held mixer, to make this frosting. 2)When cooking the white chocolate,flour and milk "until very thick", I cooked it until it started pulling together in a "ball" away from the sides of the saucepan and following the wooden spoon in the pan. 3)The butter for the frosting needs to be at room temperature as does the chocolate mixture. 4)Beat the frosting and beat it more!--it will reach whipped cream consistency and hold up on the cake at room temperature. 5)I recommend making this cake a day ahead of when you plan to serve it and do not refrigerate before serving. The taste and moistness of the cake will be enhanced and the frosting will not be grainy from the white sugar the second day. Definitely not a "make at the last minute" recipe, but well worth the extra time and effort it takes.  -  15 Jan 2006  (Review from Allrecipes USA and Canada)


    What an elegant cake! One tip, don't be tempted to use white chocolate chips in place of the squares. They do not melt smoothly as they are made to retain the chip shape while baking in cookies and other baked recipes.  -  27 Aug 2004  (Review from Allrecipes USA and Canada)


    Hi! I've made 2 of these now. One for a Friends birthday and one for my birthday. I was a little scared by the "greasy" cake review and the "runny icing" review too. It turns out both are fairly simple fixes. Here are my tips. 1. The butter and the chocolate mixes have got to be at room temperature. This is the #1 way to mess this recipe up. 2. Both the cake and the icing get their lightness from the air you whip into the butter-sugar mix. This cake doesn't really "rise", all of the air gets whipped into the butter-sugar. When you add the flour and butter milk to the mix, keep your mixer on stir, and try not to let it get to dry or too wet or to dry while mixing. If your butter or your chocolate is warm, or you get it dry and the air bubbles break out of the mix, it turns out really thick like Jiffy-mix cornbread. See tip #1. 3. The icing whips up and has a final consistency that is thicker than whipped cream. If your butter is too cold or you try to soften it in the microwave, it comes out runny. If you put the chocolate in too hot, it comes out runny. Runny icing, unlike flat cake, can be saved. Leave it in the mixing bowl and stick it in the fridge. You should be able to whip most of the air back into it after it cools. 3. The tip about leaving it on the counter overnight is spot on. A lot of the sugar crystals dissolve into the butter and it gets creamier. Definitely better on day 2. 4. You can't ice the cake while it's warm from the oven.
