Why is the pudding turning the cake into a soggy mess instead of sinking cleanly into the holes? Achieving structural integrity in a poked cake relies entirely on managing thermal thresholds. Pouring liquid pudding into a hot crumb causes the starch to gelatinize prematurely on the surface rather than flowing downward. Bake the base in a nine-by-thirteen-inch pan at 350 degrees Fahrenheit, then let it rest for precisely 15 minutes before punching channels spaced one inch apart. This intermediate resting window allows the crumb to firm up enough to hold distinct cavities without collapsing.
Building a stable topping requires sequential whipping stages. Cream cheese must sit at room temperature for 30 minutes to soften; otherwise, it will form stubborn lumps rather than a smooth base when beaten on high speed for five minutes. Incorporate three tablespoons of heavy whipping cream to loosen the density before streaming in the rest of the 16-ounce carton. Powdered sugar enters only after the cream thickens, acting as a stabilizer that prevents weeping during extended refrigeration.
