Spray a 9 x 9" baking dish with non-stick spray.
In a separate bowl, whisk one egg.
Next add the softened butter and combine.
After the egg and butter are combined, add the dry cobbler mix.
Mix all the ingredients until a thick dough is achieved. It is okay if it's a bit crumbly.
In the baking dish, pour the can of boysenberries. Do not drain them.
Now, spoon dollops of the dough mix evenly over the boysenberries.
Place into the oven and bake at 375º for 35-45 minutes. The edges should be golden brown and the boysenberries bubbly. Let cool for at least 10 minutes before eating.
