Preheat your oven to 375°F (190°C).
In a mixing bowl, combine the softened cream cheese, granulated sugar, egg, vanilla extract, and lemon zest. Use an electric mixer to beat until smooth and creamy. Set aside.
Open the tubes of refrigerated crescent rolls and unroll them on a parchment-lined baking sheet. Arrange the triangles in a circular shape, overlapping the edges to form a ring.
Spoon the cream cheese filling onto the center of the crescent roll ring. Spread it out evenly, leaving some space at the edges.
Spoon the raspberry pie filling over the cream cheese layer, distributing it evenly.
Starting at one point, fold the triangles of the crescent roll over the filling, tucking the ends underneath to seal the ring.
Place the baking sheet in the preheated oven and bake for about 20-25 minutes, or until golden brown.
While the ring is baking, mix together the powdered sugar and milk in a small bowl until smooth.
Once baked, remove the ring from the oven, let it cool for a few minutes, and drizzle the glaze over the warm ring.
