My Grandma made this when Mom was a child & both served it to their families. Also called "Depression Cake" because even then, you had "just a cup" of something. Often, Gram would trade a cup of sugar for a neighbor's flour or a different fruit was swapped. Canned was less costly and tastes better in this. There are dozens of variations and our favorites include: pineapple, 1/2 cup nuts, pears, prunes, dates, apples, raisins, and the brown sugar "sauce" I've added. My dad loved this; always had to have a "warm dessert" with milk. Some Enjoy!
Preheat oven to 375 degrees and spray cake or pie pan with non-stick cooking spray. Drain the cup of fruit; if using fresh applies, cut into 1/2" pieces.
Mix the fruit and granulated sugar, adding the flour and baking soda slowly and mixing as you go. Add one half of the brown sugar. Stir with a spatula until smooth. The batter should be smooth, except the chunks of fruit. Crumble the remainder of brown sugar on top of the cake.
Bake for approximately 30 minutes, checking every five after that. Cake is done when middle springs back, sides pull in slightly and tester comes out nearly dry. Note: the top will be very sticky; meant to be very moist. The brown sugar caramelizes and adds a nice taste and texture. Serve warm with whipped cream or slice from the pan with a glass of milk! Keep the cake covered with plastic wrap or waxed paper at room temperature for 3-4 days. Freezes very well for future use.
