Indulge your PSL obsession with these pumpkin spice cookies. Instant espresso powder gives these soft, cakey cookies a subtle yet recognizable coffee flavor. Spread with cream cheese frosting (with more pumpkin pie spice flavors) and sprinkle with cinnamon to finish. And, go ahead, drink a pumpkin spice latte while you eat them for the full PSL experience. After all, it's only fall for so long (though we'd eat these cookies year-round). To make these cookies kid-friendly, simply omit the espresso powder.
