Preheat your oven to 350° F.
Put your Inspiration Bakery and Mixes Pie Crust Mix into a mixing bowl.
Remove our butter or margarine from the refrigerator and, with a sharp knife, cut it into tiny cubes. Add your butter or margarine to the pie crust mix.
Using a pastry cutter or fork, blend the pie crust mix and the butter or margarine cubes together until it develops pea-sized pieces. Do not blend vigorously. You want crumbly small pieces.
In another mixing bowl, whisk your heavy whipping cream or other milk, egg, vanilla extract, and apple cider vinegar together.
Pour your wet mixture over your pie crust and butter or margarine mixture and gently stir just enough to get the dough wet. Do not blend vigorously. You still want to retain the small pea-sized pieces.
Use a spoon to scoop out pie dough and drop random dollops of dough over the top of the berry mixture. You should be able to see the berry mixture between the dough dollops. Use up all of the pie-crust dough.
In a small bowl or cup, blend up your cinnamon-sugar sprinkle. When done, sprinkle the mixture over the tops of the pie-crust dough dollops.
Put your Mixed Berry Cobbler in the oven and bake for 50-55 minutes, until the berry mixture bubbles up. Remove and let rest for 10 minutes. Serve warm with ice cream, whipped cream, whipped cream substitute. Enjoy!
