How to Make Box Cake Taste Homemade: Complete Troubleshooting & Recipe Guide
Q1: Will adding both pudding mix and sour cream make the cake too dense?
Yes. Combining a full box of instant pudding with 1/2 cup of sour cream can overload the batter with fat and modified starch, causing the center to sink under its own weight. Choose one primary texturizer: use instant pudding for a springy, sponge-like crumb, or sour cream for a tender, velvety crumb reminiscent of pound cake.
Q2: Can I use salted butter instead of unsalted butter?
Unsalted butter is preferable because commercial cake mixes already contain significant sodium levels (typically 300mg to 380mg per serving) used as preservatives. If you only have salted butter available, proceed with the swap, but avoid adding extra salt to your frosting or soak.
Q3: How do baking times change when adding milk, butter, and extra eggs?
Because enriched batters contain more sugar, dairy solids, and fat, they take slightly longer to bake and brown faster. Lower your oven temperature by 15°F (for instance, bake at 335°F instead of 350°F) and extend the baking time by 3 to 6 minutes. Check doneness with a wooden toothpick inserted into the exact center of the sponge; it should emerge with a few moist crumbs attached, never wet batter.
