Preheat the oven to 375 degrees.
In a medium sized bowl, beat the cream cheese, sugar, lemon extract and lemon curd until smooth and creamy.
Unwrap the crescent rolls and press them flat. Spread about a tablespoon of the cheesecake mixture over the top of the dough and roll it up into a crescent shape. Repeat until all the dough has been used. Brush the tops with the melted butter.
Place them on a baking pan and bake for about 10-11 minutes, until lightly golden brown. Remove and let cool.
To make the glaze, place the powdered sugar and squeeze enough lemon juice to make the glaze into a consistency that it can be drizzled over the crescent rolls.
