Standard chocolate sheet cakes are typically baked at 350 degrees Fahrenheit, but this formulation requires a hotter oven set at 400 degrees. Boiling the initial fat and water mixture denatures proteins differently than standard creaming methods do. That boiling step dissolves the sugar completely before the dry ingredients enter the bowl, creating a fluid batter that behaves unpredictably if you attempt to halve the measurements. Halving a two-egg recipe leaves you measuring fractional eggs, which alters the structural crumb.
Scaling this 9x13 pan yielding sixteen portions up to a half-sheet pan requires multiplying all ingredients by 1.5, not 2, due to surface area constraints. When swapping margarine for butter, use an equal 1:1 ratio, but expect a denser final crumb because plant-based spreads contain varying water percentages. Buttermilk can be replaced by mixing one tablespoon of lemon juice per half cup of standard milk and resting it for ten minutes.
