I wanted to get you oriented, as I've posted quite a few pumpkin recipes through the years. Pick and choose!
Pumpkin Whoopie Pies
Pumpkin Pudding Cake
Pumpkin Eclairs (with Pumpkin Pastry Cream)
Sweet Potato Sweet Bread (can be adapted with 1 to 1 ration replacement with pumpkin purée)
For leftover pumpkin purée, gnocchi!
