The dough is very soft. And if you feel like it's too sticky to handle, you can refrigerate it for a couple hours.
To make the cookies:
Preheat the oven to 350°.
Sprinkle a layer of flour onto your clean countertop. Place half of the dough onto the flour. Sprinkle the top with a dusting of flour and roll it out, with a rolling pin, to about 1/8 - 1/4 inch thick. If the dough wants to stick to the counter, lift up the edges and add more flour.
Use a round cookie cutter or cup to cut out circles of dough. (I used my 2 1/4-inch cutter, but you can make them smaller or bigger according to how big you want your cookies).
Place the dough circles, at least an inch apart, onto a parchment-lined cookie sheet.
Put a heaping teaspoon of raisin filling onto the top of each circle. (You will need to adjust the amount according to the size of your cookies. I used a heaping teaspoonful for 2 1/4" cookies.)
Roll out the remaining dough and cut more circles of the same size. Using a thimble or tiny round object, cut a small hole in the center of each circle for the top. (Dip the thimble in flour to prevent the dough from sticking.)
Place the top circle over the raisin filling and lightly press the edges together.
Use all the scraps/remaining dough and roll it out to make more cookies until no more dough is left.
Bake the cookies at 350° for about 11 minutes or until the bottom edges are lightly browned.
Let them rest on the tray for a moment, then transfer them to a wire rack to cool.
Store in an airtight container. Place parchment between the layers, and I recommend freezing any cookies that won't get eaten within three days, to keep them fresh.
Notes
If desired, drizzle a powdered sugar glaze over the top of the cookies.
