In a large bowl, beat together the cream cheese, butter, and sugar. Add in the vanilla.
In a medium bowl, whisk together the flours and baking soda. Gradually add the flour mixture into the butter/sugar mixture. Making sure to fully incorporate.
Put cookie dough on a large sheet of waxed paper, and wrap tightly. Refrigerate for at least 1 hour or up to 3 days.
Take dough out of refrigerator. Preheat oven to 350°F.
On a lightly floured surface, roll ½ of the dough to a ¼-inch thickness. Cut out cookie shapes using a 2-in cookie cutter of your choice. Place cookies on a parchment lined baking sheet. If desired, top with sprinkles (or you can ice and decorate after baking). Refrigerate for at least 15 minutes on baking sheet.
Bake cookies for 8-10 minutes in a preheated oven, rotating the pans halfway through baking, until the edges are barely brown. Cool cookies on the baking sheet for 2 minutes; then cool them on wire racks until completely cooled.
Ice cookies and decorate if desired. Store in an airtight container for up to 3 days.
Notes
*these cookies aren't super sweet, so you will probably want to at least add sprinkles. They'd be good iced, too
