How to add pistachios in a white chocolate mudcake
Dust all three inclusions (the chips and nuts) and then place half of the plain batter (that has no inclusions added) in the pan(s), add the inclusions to the remaining batter and mix lightly. Pour that batter evenly over the batter already in the pan(s) and bake. Don't cut the pistachios in more than half or they will be too small.
