Preheat oven to 350. Spray 2 9x5 loaf pans with baking spray or line 24 muffin cups with foil liners.
Whisk pumpkin, oil, sugar, and eggs. Stir in flour, salt and spices. Divide batter evenly between pans/cups.
Bake until the top is a deep red color and toothpick comes out clean, 40-45 minutes for and and 20-25 minutes for cupcakes.
Let cool. Transfer to serving plates. Combine powdered sugar and glaze to make a glaze, adjusting consistency if necessary. Drizzle caramel over one loaf and glaze over the other. (If you're doing cupcakes, drizzle 12 with caramel and 12 with glaze).
