Butter first, then pumpkin in the same skillet. Don't wash it between.
Toasted oat flour 100 g → 80 g
Steel-cut oats on a sheet pan, 350 °F, 8–12 min, stir once. Cool completely before grinding. Grind 45–60 s, sift, re-grind the tailings.
Browned butter 200 g → ~167 g
10–12″ light-bottomed skillet, medium, swirling, 6–9 min. Pull at amber. Scrape into the mixing bowl, fond included.
Cooked-down pumpkin 425 g can → 360 g
Whole can into the buttered skillet. Medium, stirring and spreading thin, 8–12 min, until brick-colored, no longer sputtering, and it holds a furrow. Spices go in for the last minute. Start weighing at minute 7.
Overshot? Whisk milk back in to 360 g. Cool to room temp. Freeze the unused 180 g flat in a bag. It's already spiced for the next loaf.

Oven to 325 °F, rack in the middle. Spray two 1.5 qt glass pans, line with parchment, overhang on the long sides.
Whisk the dry together, breaking up malt clumps.
Whisk both sugars into the cooled browned butter, fond and all. Add the sour cream, then the eggs one at a time, then vanilla.
Whisk in the 360 g of pumpkin until uniform.
Add the dry all at once and fold by hand until a few streaks remain. Fold in pecans if using. Don't rest the batter.
Divide by weight, 850 g per pan. Smooth the tops; pepitas on now.

Glass pansNever set a hot Pyrex pan on cold stone, a wet rack, or a damp trivet. It can shatter.
Cream cheese frosting optional
Kept tangy and light on sugar, since the loaf is already sweet. Frost only fully cooled loaves.

Beat the cream cheese and butter on medium until completely smooth, 1–2 min. Any lumps now stay lumps.
Add the powdered sugar, salt, vanilla, maple syrup and cinnamon. Mix on low until it disappears, then medium for 30 s. Stop there. Overbeating turns it runny. The maple version sets softer; chill 15 min if it's loose.
Spread over the tops of the cooled loaves, about 200 g each. Chill 20 min to set before slicing.
Frost it or spread it
Frosted loaf fridge · 4 days
Spread over the cooled tops and chill 20 min to set. Once frosted, the loaf lives in the fridge.
As a spread fridge · 5–7 days
Pack into an airtight container and keep the loaf plain on the counter. Let the spread sit out 10 min, or give it a stir, before using. Best on a slice warmed in a toaster oven.

Why each choice
Canned purée, not pie filling. Filling is pre-sweetened and pre-spiced. Libby's runs drier than store brands; the 360 g target evens it out.
Cook-down drives off the canned note, browns the edges, and picks up the browned milk solids in the skillet.
Sour cream keeps malt, dark brown sugar and spice from reading flat. Full-fat only. Mascarpone works for a richer loaf: scant 1¾ tsp salt, tent 5 min earlier.
Maple goes in the frosting, not the batter. Baked, it disappears behind the spice and malt, and its water works against the gummy-band risk.
Doneness: pumpkin holds water to the end. A loaf that looks done at 195 °F will have a gummy band.
Malt with pumpkin lands closer to spice cake than caramel. Expected.
Half can: cook down the whole can, use 180 g, freeze the rest flat in a bag.

Troubleshooting
Gummy band near the bottom: cook pumpkin down to 340 g next time, nothing else.
Dry or crumbly: back up to 380 g pumpkin.
Bland: spice up 25%, then salt to 1¾ tsp.
Too sweet: granulated sugar down to 40 g. If frosted, try it plain first.
Sunken middle: check the soda measurement.
Top too dark: tent at 35.
Sides or bottom too dark: the glass. 315 °F, add 5–10 min.
Pumpkin scorched: heat too high or spread too thick. Medium, stir constantly at the end.
