I love bringing a batch of these pumpkin spice rum balls to a fall get-together with friends, since they come together in about 20 minutes and never touch the oven. For the flavor, I add pumpkin pie spice and a splash of Rumchata for a warm, creamy edge, and every single time, someone asks if there's real pumpkin inside(there isn't, it's all spice). If you want a boozy, no-bake treat that tastes like pumpkin pie in cookie form, this is the one to make.
