I am trying to search through the recipes.

I think I am gonna make a chocolate cake and I have a box of white chocolate pudding mix that I want to make a filling out of, just make it as a pudding and fill cake or do y'all have a better recipe?

I have used the pudding mix to sprinkle into Cool Whip or Whipping Cream and it makes a really nice filling.

I do the same. Mix the dry pudding mix into 1 c whipping cream, 1 cup milk...add whatever flavour you like. I love a little bit of mint, and shaved mint chocolate... or a little bit of coconut extract......or a touch of vanilla and some shaved white chocolate....etc etc. possibilities are endless. I have also added a touch of strawberry flavour and a few teaspoons of strawberry jam. Have fun!
