-
To make the dough: In a medium-sized bowl, beat together the butter and sugar, then add the egg, vanilla, salt, baking powder, cinnamon, and ginger, beating until smooth
-
Beat in the flours and oats; the mixture may look dry at first, but don't worry, it'll come together.
-
Divide the dough into two pieces, wrap each piece in plastic wrap, and refrigerate for about 30 minutes.
-
Preheat the oven to 350°F. Lightly grease (or line with parchment) two baking sheets.
-
To shape the cookies: Working with one piece of dough at a time, roll it into a circle about 14" in diameter. Use your favorite cutters to cut out cookies, re-rolling and cutting the scraps.
-
Place the cutout cookies on lightly greased or parchment-lined cookie sheets; set them fairly close together, as they don't spread.
-
To bake the cookies: Bake the cookies for about 9 to 10 minutes: the shorter amount of time will make softer cookies, the longer amount of time, crisper cookies.
-
Remove the cookies from the oven, sprinkle with cinnamon sugar, and transfer to a rack to cool.
-
Repeat with the remaining dough. Decorate as desired.
