Simmer berries in 1 cup of water with added sugar for about 15-20 minutes while preheating oven to 350 degrees.

Mix together oats, flour, sugar, brown sugar in a bowl.

Add in 3 tablespoons of cold butter cutting up with a fork or pastry blender *see link on blogpost (Alternatively, you can use a cheese grater with the butter)

Add berries to a 9x13 casserole dish and top with oat mixture, bake for 15 minutes.

While baking, measure self-rising flour into a small bowl, stir in water a little at a time making sure not to get dough too runny. You want to be able to scoop it with a spoon without it running off too much. 

Remove berry dish from oven and dollop the "cloud-dough" on top. 

Using a cheese grater, grate remaining 5 tablespoons butter on top, if desired sprinkle a bit more turbinado sugar on top and return to the oven.

Bake until toothpick comes out of "clouds" clean - let cool at least 10 minutes before eating.
