Cream together butter and sugar with a mixer.
Add egg and extract and mix well.
Sift together flour and salt.
Add flour to the wet mixture a little at a time until well incorporated.
Place dough into a ziplock bag and chill before rolling out.
Dust the embossed rolling pin with a little flour in a sifter to prevent sticking and shake to remove excess.
Roll the dough onto parchment paper on a flat cookie sheet with a regular rolling pin first to desired thickness-(keep in mind that pressure with the embossed rolling pin will decrease thickness.) Then roll the dough once in one direction with the embossed rolling pin, applying even pressure, ensuring evenly imprinting the image.
Cut cookies using a heart cookie cutter or desired shapes.
Remove extra dough from parchment so that only cut cookies are left on the cookie sheet.
Place the cookie sheet into the refrigerator for a few minutes to make sure that the cookies are cold before baking. This helps hold the "embossed" image a little better.
Preheat oven to 400 degrees while cookies are chilling.
Once chilled, bake cookies in preheated oven for 10-15 minutes until tops appear dry rather than shiny. Remove before edges begin to brown.
Remove cookies from the oven and place cookie sheet on a cooling rack while preparing the chocolate or almond bark for dipping.
Add a few squares of almond bark to a quart sized freezer bag and microwave in 20 second increments until melted, turning over bag between warming.
Using kitchen shears, snip a tiny corner off for piping chocolate onto cookie.
Pipe chocolate edge on cookies and top with sprinkles.
Let cool and set completely before moving them from parchment paper.
