In a saucepan, cook the heavy cream, molasses and sugar over low-medium heat until warm. Add the butter and cook until melted.
Remove from heat and stir the remaining ingredients into the syrup.
Turn the warm dough out onto a piece of plastic wrap, flatten, wrap tightly and refrigerate for at least three hours or overnight.
Working with half the dough, knead it on a lightly floured surface until malleable, then roll it into a 2mm thick rectangle.
Using a fluted pastry cutter, cut the dough into 1 1/2" strips. Cut from one corner to the one across from it, then cut in 1 1/2" diagonal strips to create the diamonds.
Repeat with remaining dough.
Transfer the cookies to a parchment paper-lined baking sheet, top with half a blanched almond and bake at 350F for 5-8 minutes, or until beginning to brown.
Notes
Cutting the dough: Don't have a fluted pastry cutter? You can use a pizza cutter instead or use cookie cutters to create fun shapes.
Storage: Keep at room temperature for up to 2 weeks.
