In a large bowl, beat butter and sugar until fluffy. Add Garam Masala and combine well.
Stir in flour slowly. If dough ends up too crumbly, add more butter 1 tablespoon at a time.
On a lightly floured surface, roll out dough and make cookies using a cookie cutter or make squares with a pizza wheel. Bake on an un-greased cookie sheet for 12-14 minutes.
Remove from pan and cool on wire rack. Pairs nicely with eggnog, spiced chai, or hot apple cider.
