Don't skip the 5-minute steep — it is the whole difference between a real pumpkin spice latte and spiced milk. The strained pumpkin-spice milk keeps in a sealed jar in the fridge for up to 4 days. Reheat gently on the stove over low heat and whisk to recombine. I don't recommend freezing, because the milk texture turns grainy. For a dairy-free version, oat milk is my favorite swap. For a kid-friendly cup, use half the coffee and extra warm milk.
