Pre-heat oven to 375 & spray a 8x8 or 9x9 pan with baking spray. Dice apple slices. Add to the prepared pan and toss with the lemon juice and 2 tablespoons of the sugar.

Spread the topping over the apples in the pan. Press down slightly.
Bake for 30-35 minutes or until the apples are soft. (If the topping starts to get too dark brown at any point, cover it loosely with a piece of foil and continue baking.) Let cool slightly and serve warm or at room temperature.
