For baked apple: Peel and core 1 apple (your favorite baking apple. I used a Jona-Gold today) Cut in half horizontally. With a fork, mix together the brown sugar, cinnamon, raisins and butter. Stuff the middle of each half with this filling. Cut 1 pastry sheet in half. Completely cover and seal each apple half. Place on a baking sheet sprayed with cooking oil or use parchment paper.For frosting:Melt 1 T butter in a baking dish. Add 1 C powdered sugar. Add enough milk to make the consistency of the frosting drizzle, approx. 1-2 T. When baked apple is cooled a bit, drizzle frosting over top. Serve with a little ice cream, if desired.
