#### **Step 1: Prepare the Rolls**
Preheat oven to 350°F (175°C).
Place the Hawaiian rolls on a baking sheet, keeping them connected.
Using a sharp knife, carefully create a small indent in the center of each roll without cutting all the way through.
#### **Step 2: Make the Cheesecake Filling**
In a mixing bowl, beat the softened cream cheese, sugar, vanilla extract, egg yolk, and lemon zest (if using) until smooth and creamy.
#### **Step 3: Fill the Rolls**
Spoon or pipe the cream cheese filling into the center of each roll indentation.
Bake for 12-15 minutes, or until the rolls are golden brown and the filling is set.
#### **Step 4: Prepare the Icing**
In a small bowl, whisk together powdered sugar, milk, and vanilla extract until smooth.
#### **Step 5: Drizzle & Serve**
Let the danishes cool slightly before drizzling with icing.
Serve warm and enjoy!
