Roll out the puff pastry sheet thin. Sprinkle flour if the dough gets tacky.
Cut the sheet into 16 rectangles.
Add a spoon of guava paste onto half of the rectangles.
In a bowl, mix cream cheese and confectioner's sugar really well. It's fine if the cream cheese has lumps unless you want to use a mixer to mix (unnecessary).
Now drop a spoon of this cream cheese on top of the guava paste. Smear the filling but don't spread it to the edges.
Brush the edges with milk so the tops can seal.
On the remaining puff pastry rectangles, make three slits with a knife in the center. These will be the top layers of the pastry.
Press slit pastry rectangles onto the filled ones and press gently with your finger. If you use a fork to crimp the edges, the pastry will not rise as much so just use a gentle touch when sealing the egdes.
Brush the tops of the pastry with cold milk and sprinkle with raw sugar.
Let the pastries chill in the freezer for 10 minutes. Next, bake at 400 degrees F for 20-25 minutes or until deep golden brown.
Let cool for 10 minutes and enjoy with that coffee!
