Before you begin, thaw the puff pastry according to package directions. This usually takes 40-60 minutes.
Preheat the oven to 375 F. Grease the sides of a muffin tin with butter and line the bottom with parchment paper or the bottom cut out of a paper muffin liner. Set aside.
In a medium sauce pan combine sugar, corn starch, and apple beer. Whisk over medium heat until the mixture comes to a simmer. Cook for an additional 90 seconds until the mixture is thick like syrup.
Microwave the cream cheese for 30 seconds until it is very soft. Whisk it into the apple mixture. Set aside.
Squeeze the lemon into a medium bowl that can go into the microwave. Fill it about half way with water. Slice apples in half from stem to blossom end. Remove the core and the skin around the stem and blossom end.
Starting at the stem end, slice apples about 2mm wide, placing each slice into the lemon water as you cut. The best way to do this is on a slicing tool. (Too thin they are prone to burning, too thick and you can't roll the rose).
Microwave the apples in water for about 3 minutes.
Lightly flower a work surface and roll out the puff pastry until it is about 12" x 9". Cut the dough into six strips about 2" x 9".
Spread a teaspoon of filling over each strip. Reserve leftover filling to serve with pies as desired.
Drain the apples and place a row of slices from left to right across each strip of pastry dough. Each slice of apple is placed so it covers about 1/2 of the slice before it. Place the apples in such a way that the bottom corners of the dough can be folded up to become even with the top corners. See picture for example.
Sprinkle with cinnamon if desired. Fold bottom of pastry up to meet top corners. Gently roll each strip from left to right into a rose shape. Place in prepared muffin tin and bake at 375 for until golden brown and puffed, about 40-45 minutes. If the apples start to singe, try moving the pan to a lower rack of the oven.
Dust with powdered sugar or drizzle with salted caramel sauce and serve hot with or without butter pecan ice cream.
