How to Make Perfect Sandwich Cookies
Rolling the Cookies
There's a good amount of butter in this recipe, which is a good thing for taste and texture but could make the dough a bit more difficult to roll out.  Chilling the dough beforehand makes the rolling easier.
Most recipes typically call for rolling the dough out while it is soft, but giving this dough an hour in the fridge makes it less sticky and easier to roll.  Dividing the dough into two sections also makes rolling easier. 
Making Sandwich Cookies The Same Size
Having two cookies the same size is the key to a perfect sandwich cookie.
Once you've rolled and cut, I recommend chilling the cookie dough again before baking to ensure the cookies retain their shape and size.
Cutting the Top Cookie
To get the cutout that displays the filling, you can use any shape of nesting cutters you want.  Don't be afraid to mix shapes to create unique shapes. 
I used hearts for Valentines Day, but the same cookies can be made in many different shapes.  If you want to make hearts like mine.  Click here to get a similar set on Amazon.
Top tip: Try to bake the tops with the center cut out on their own cookie sheet, as they tend to bake just a little faster.
Assembling the Cookies
Don't add too much, my filling.  It will ooze out the sides and make a mess.
Add a heaping teaspoon in the middle, spread it just a little and then pressed the cookies together.  As the cookies set, the fluff spread on its own to fill the inside.
