Mulberry Crisp Fresh From the Oven

I picked white and black mulberries, then mixed melted butter, instant oatmeal, flour, brown sugar, a little salt and vanilla. Then put some of the flour mixture on the bottom of a buttered pan, spread the mulberries over that, then evenly distribute the rest of the flour mixture over the berries. I will bake at 350 F for 20 minutes then check on it. It's done when the top has some visible juice and is slightly brown. For this one, I took it out after 20 minutes, cut into pieces and put a small piece of butter on each piece, because it seemed a little dry, then I put it in the oven at 300 F for 15 minutes, and it is perfect now!
