Preheat the oven to 375 degrees F. Line 2 baking sheets with parchment paper and set aside.
In a large bowl, mix together the flour, sugar, salt, baking soda, and spices.
Mix the butter into the dry ingredients using your hands.
In a small saucepan, warm the molasses and cream over low heat so they blend together. Stir often. Add the molasses and cream mixture to the bowl and mix into a dough.
Remove the dough from the bowl and place on a lightly floured work surface. Roll it out to a 1/4-inch thickness. Cut into circles. A round cookie cutter or a cup works great for this. You can make them as big or small as you want, but 3 or 4 inches is probably best.
Bake for 10 minutes, until firm on the edges and slightly soft in the centers.
Let cool slightly, then dust with confectioners’ sugar and serve.
