Blackberry Cobbler

Making this for my girls tonight. This is their favorite dessert!
Wish I could eat it, but it has dairy, sugar and gluten. 
Maybe I'll have to come up with a gluten, dairy, sugar free version.

Ingredients:
16 oz frozen blackberries
1/2 cup sugar 
1/3 cup sugar or Splenda or 1 t Stevia
2 T butter 
1 1/2 pkg cream cheese or 12 oz
1/3 cup fat free milk
1 cup and 2 T Bisquick
1/4 cup and 2T uncooked oats

Directions:
Bring blackberries, 1/2 c sugar and butter to a boil in large saucepan over medium heat. 
*If you are using all sugar and no Splenda or Stevia, then add all of the sugar (1/2 c and 1/3 c) to the saucepan. Stir gently until butter melts and sugar dissolves; remove from heat.

Beat cream cheese and Splenda or Stevia until fluffy. 
*If you are using all sugar, just beat cream cheese until fluffy.
Add milk and beat until smooth. Stir in baking mix and uncooked oats.
Spread 2/3 of cream cheese mixture onto bottom of 8” square pan.
Spoon blackberry mixture evenly over cream cheese mix.
Dollop remaining cream cheese mix over blackberry mix.
Bake at 350 degrees for 35 minutes or until brown on top.
