Blackberry Cobbler Recipes

I'm looking for a no-fail recipe for blackberry cobbler. I have a freezor full of blackberries which we grew last year but I haven't been able to make a cobbler yet that came out right. It was either too runny or too much bread. Cooking is always a challenge for me anyway, especially when I try something new. I say that, but I have to admit the blackberry jam I made last summer came out excellent - just a fluke. I didn't know what I was doing. thanks
