For pumpkin filling, in a small saucepan, melt the 3 tablespoons butter. Add ground cookies, bay leaf, dash salt, nutmeg, saffron, cloves, cinnamon, and red pepper. Heat for 1 to 2 minutes, stirring until combined. Remove from heat. Remove and discard bay leaf. Stir in pumpkin, the 1/3 cup Parmesan cheese and the bread crumbs. Cool.
