Preheat oven to 350 F. Oil your baking dish{es} {see notes above for sizes} or use a good non-stick pan and set aside.
Place tofu in a blender and blend until smooth. Add all other ingredients except plums into a blender and blend into a smooth mixture. Pour into prepared baking dish. Stir in chopped plums.
Bake in a preheated oven for 1 hour. Remove from oven and cool on a rack for at least 10 minutes {or cool, then chill in the fridge if you like it cold. I like mine nice and warm though...}. Scoop into bowls {unless using individual ramekins} and serve with a side of {non-dairy} ice cream or yogurt of your choice {optional}. Enjoy!
