This is my Moms recipe and is very easy with few ingredients. It works very well with blackberries as well as fresh peaches, just adjust sugar to taste. If using blackberries thicken slightly with cornstarch in the first step.
brown sugar, firmly packed
cinnamon and/or nutmeg
margarine or butter
1Pre-heat oven to 350 degrees . Spray an 8 inch pie plate with cooking spray. I use a round glass pyrex or fire king pie plate.
2In a sauce pan combine blueberries,water,and sugar. Bring to a boil, reduce and simmer 2 min. Stirring constantly
3Pour berries into bottom of pie plate.
4Combine the last 6 ingredients. Using a pastry blender, food processor or fork work the dough until it resembles cornmeal.
5Sprinkle the dough mixture over berries.
6Bake for 20 or 25 min. All ovens vary, check dough for doneness periodically. You want the top lightly brown.
7Serve with a scoop or two of vanilla ice cream.
