My youngest daughter is obsessed with matcha. I love matcha too. But not on her level of obsessiveness tho, lol. This is actually my 2nd try. It failed horribly on my 1st attempt; my 1st mistake is assuming white chocolate reacts the same as dark chocolate would. As soon as I mix in the butter on the double boiler, the chocolate starts to seize and splits.
In order to salvage the chocolate mixture, I added more butter. My 2nd mistake is expecting the cake batter to work the same during the final baking process. It doesn't. The end result is a gummy gooey texture with an unpleasant after taste.
After doing some research online and realizing my mistakes, I decided to give it one more shot. To my surprise, it worked on my 1st retry! I incorporated a different technique in combining butter and white chocolate together. The end result is almost the same as brownies: dense, fudgy and moist with layers of aftertaste.
It wouldn't be called death by matcha if there isn't any matcha ganache layer, right? Anyway, if you are a matcha lover, you really need to give this recipe a try.
