Preparation
Combine rhubarb, apples, ½ cup white sugar, and water together in a saucepan; bring to a boil.
Cook and stir rhubarb mixture for about 10 minutes or until rhubarb is tender and compote is thickened.
Preheat oven to 350 degrees F (175 degrees C). Grease an 8-inch square baking dish.
Mix ⅔ cup white sugar, ¼ cup margarine, egg, and vanilla extract together in a bowl.
Stir milk and stir into the sugar mixture.
Whisk flour, baking powder, and salt together in a separate bowl.
Mix flour mixture into the wet mixture until batter is just moistened; pour into the prepared baking dish.
Spoon enough compote over the cake to make about ½-inch-thick layer, reserving any leftover compote for other uses.
Stir oats, ½ cup margarine, ½ cup white sugar, and cinnamon together in a bowl until crumbly; sprinkle over compote layer.
Bake in the preheated oven for 30 to 40 minutes or until a toothpick inserted in the middle of the cake comes out clean.
