My mom's recipe:
For a 9" square pan. Melt one stick of margarine in the pan in the oven (325F.)...or almost one stick. After it's melted spoon over one regular-sized can of drained peaches. Pour over the margarine and fruit a mixture made of 1 cup plain flour, 1 teaspoon baking powder,
1/8 teaspoon salt and around one cup of milk---less milk if you want the dough to be more stiff. It ought to pour over the margarine and not be too sticky. And note: this doesn't require a mixer, but only a bowl and spoon.
Bake at 325F. for around 25 minutes or so. Notice that my measurements aren't exact, because it's just not necessary to be too picky. I tripled this recipe tonight and put it in our largest aluminum baking pan which measures at around 13" long. It baked forEVER! :) For tripling the recipe I used 2 sticks of margarine and not 3 like you would if you measured exactly. And I used just over 2 cups of sugar for tripling as well. Adjust as you like. It's a very friendly recipe!
Served in nifty old bowls with vanilla ice cream makes wonderful comfort food. And no, there's no photo. We ate it. The cobbler, you know.
