Full disclosure: the gingersnap cookie crust in this pie and a few others below does call for a quick (like, 15-minute) pre-bake in the oven. That should be easy to do ahead of time, BUT if you’re really opposed to that idea or for some reason don’t actually have an oven, you can also just buy a pre-made cookie or graham cracker crust.
20. Banoffee Surprise Pie
SPOILER: The surprise is a layer of chocolate! “Banoffee” = banana + toffee, and this is a dessert British people have been appreciating for a long time. What better occasion than Thanksgiving to co-opt it? Get the recipe at Sprinkled With Flour.
