Preheat over to 350 degrees. Coat a large baking sheet with cooking spray or use parchment paper.
In a medium bowl combine apples, brown sugar, lemon juice, and cinnamon, toss to coat apples.
Place wonton wrappers on a flat surface. Drop apple mixture by teaspoonfuls onto centre of each wrapper. Moisten edges of wrapper with wet fingers, fold over one corner to make a triangle and press sides together to seal. Transfer filled wrappers to baking sheet and coat surfaces with cooking spray.
Bake until wontons are golden brown, about 15 minutes. Place wontons on individual plates and dust with powdered sugar. Serve with ice cream on the side.
Yields 4 wontons, 1 tsp of powdered sugar and 1/2 cup of ice cream per serving.
