Instructions
In the bowl of a stand mixer combine butter/margarine and sugar on medium speed, and beat till well combined, about 1 minute.
Beat in vanilla; add egg and beat until thoroughly combined, scraping down the bowl as needed.
In another bowl combine flour, leavening(s) and salt. Add to creamed mixture and beat on low until just combined.
Chill dough 1-2 hours.
Heat oven to 400F and line two baking sheets with silpats or parchment paper.
Using a #70 disher (1 Tbsp) or a spoon, roll dough into small balls the size of small walnuts.
Combine 2 Tbsp. sugar and spices in a small bowl.
Roll dough balls in sugar and spice mixture, being sure to thoroughly coat every bit with sugary-spicy goodness.
Place cookies at least 2" apart, and bake 7-10 minutes, rotating sheets halfway through, until they are lightly browned. Cookies will puff a bit while baking but flatten as they cool.
Cool on sheets 5 minutes and transfer to wire rack to cool completely.
