Just do yourself a favor and keep all these things in the house at all times. Obviously you can swap out the ice cream and jam flavors, but vanilla and PB are perfection in a shake. The raspberry jam makes it extra nice. PS - you could totally go vegan here with a dairy-free ice cream (love the Trader Joes Soy Creamy Vanilla, or Coconut Bliss brands are both good choices). Peanut-free kids? Yes, almond butter is also delishhhh.
