¼teaspoonvanilla extractnot in original
1largeegg
1teaspooncinnamon
¼teaspooncayenne pepper or ground chile or chipotle powder
2tablespoonsof granulated sugar
Instructions
Preheat oven to 400 degrees F. Line cookie sheet with parchment paper or hold off on this step if you intend to chill the dough.
Mix together flour, cocoa powder, cream of tartar, baking soda and salt; set aside.
Cream the butter and sugar with an electric mixer on high for about 2 minutes. Add vanilla and egg and beat until combined. By hand, stir in the flour mixture gradually.
Combine the cinnamon, pepper and 2 tablespoons of granulated sugar in a small bowl. Scoop up tablespoons of cookie dough (slightly heaping) and make 1 inch balls. Roll the balls (or just the tops) in the cinnamon sugar.
Space cookies about 3 inches apart on cookie sheet and bake for 10 minutes or until they start to crack. Transfer to wire racks to cool.
Notes
If you don't weigh your flour, make sure to stir it very well before measuring.
For the cocoa, natural style (e.g. Hershey's) works best. Dutch cocoa is acceptable, but the cookies will be thinner.
Instead of rolling the dough into balls right away, I sometimes plop rounded tablespoons of dough onto a foil lined baking sheet and chill the baking sheet with the portioned dough pieces for about an hour. That gives me time to clean up the rest of the mess and come back to the cookies later. When I'm ready to bake, I just roll the portioned dough pieces between the palm of my hands, roll in sugar and bake.
