Difficulty: Moderate
Preparation time: 1 hour

1. Preheat oven to 475 degrees. Butter a 2-quart baking dish, then add the pie filling (use a spatula to get every bit of filling) and set aside.
2. Place biscuit mix in a large bowl, then, using a cheese grater, grate the butter into the mix. Using your fingers, toss the butter and biscuit mix together. Add the milk and stir till the dough just comes together. Take care not to overwork. 
3. Turn the dough out on a well-floured work surface and dust the top with flour. Press into a ½” thick rectangle (about 5”x15”). Starting at one of the short ends, fold the dough into fourths. Rotate 90 degrees and repeat the pressing and folding two more times.
4. With the dough pressed about ½” to ¾” thick, cut biscuits, reshaping the scraps till all used up. Place the biscuit rounds on top of the filling. Brush with melted butter and sprinkle with raw sugar, if desired.
5. Place cobbler on a baking sheet and put in the oven. Turn the oven down to 350 degrees and bake until the biscuits are golden and the filling is bubbling up, about 25-30 minutes. Let cool slightly before serving.
