Magic Peach Cobbler

3 C canned sliced peaches in juice, drained
1/2 C butter, softened
3/4 C sugar
1 tsp vanilla extract
1/2 C milk
1 C all-purpose flour
1/8 tsp salt
1 tsp baking powder

Crispy Topping:
1/3 C sugar
1/2 tsp cinnamon
1 T cornstarch
1/2 C boiling water

Preheat oven to 375 degrees.  Spray an 8x8-inch baking pan with non-stick spray.  Drain the sliced peaches and arrange them in the bottom of the baking pan.  In a large bowl, cream the butter with ¾ cup sugar.  Add the vanilla extract and mix well.  Add the milk, flour, salt and baking powder to the sugar butter mixture.  Mix until creamy.  Spread the batter over the peaches and smooth.  In a separate bowl, mix 1/3 cup sugar and 1/2 teaspoon cinnamon with the cornstarch.  Sprinkle the mixture evenly over the batter.  Pour the boiling water over the sugar mixture making sure to cover all of the sugar with the water.  This is where the magic happens and what makes the crispy topping.  Bake 375 for 40-45 minutes.  If cobbler starts to brown too quickly, cover with a sheet of aluminum foil and continue baking.  Cool slightly before serving. NOTE:   Fresh or frozen peaches can be substituted for canned peaches.  About four fresh peaches is equal to three cups.  If using a glass baking pan lower the baking temperature to 350 degrees.
