Pineapple-Onion Upside-Down Ice Cream Cake

Have you heard of Summersgiving? The Saturday after the first day of summer, have an American-Thanksgiving-style feast! Add a few special items, to celebrate Ice Cream Cake Day, Pineapple Day, Onion Day, and Orange Blossom Day. Eat it outside, because it’s also Sunglasses Day. Don’t forget pumpkin pie! It’ll be a feast to remember.
