Here's a secret: You don't need official pumpkin pie spices to make your own PSL recipe. Pumpkin spice is a blend of spices such as cinnamon, ginger, nutmeg, and allspice. You can create your own taste-alike seasoning blend with warming spices that you have on hand. I have a strong sensitivity to cinnamon, so I didn't use any cinnamon in this recipe. But you can absolutely add a sprinkling of it!
