Preheat the oven to 375F. Place the chopped pears in a bowl, add cinnamon and brown sugar. Stir. You can also use canned pears.
Place the pears on the bottom of a 9x13 baking dish. Mix cornstarch with 2 tablespoons of water, add lemon juice and pour all together into a baking dish.
Mix all dry ingredients for the dough. Melt the butter and pour it into a bowl. Stir with a whisk until smooth.
Spoon batter on top of fruit layer. Smooth out so it is even across pan and place in the oven. Bake for about 22 minutes until top is lightly browned and toothpick in center no longer has wet batter on it. (you do not want to overbake, it should remain tender)
Scoop out and serve with a scoop of ice cream. Additionally, you can sprinkle with cinnamon or powdered sugar, and top it with caramel sauce.
