Line a 10-inch springform pan with tin foil. Put the bread cubes and the pecan pieces in the pan and toss.
Whisk together the half-and-half, pumpkin, and sugar.
Add the rest of the ingredients and whisk until combined.
Pour the mixture over the bread and pecans.
Mix the custard mixture over the bread and mix well. Let this sit for 20 minutes before you bake it. Preheat your oven to 350°. Give it one more mix before you put it in the oven.
Bake in the oven for 45 minutes, or until a knife inserted in the center comes out clean.
Slice into wedges. I like to add a dollop of cinnamon whipped cream and a drizzle of salted caramel. Just for good measure.
