The Extra Ingredient For Better Boxed Cake Mixes

Boxed cake mixes always leave some things to be desired — but with just one simple tweak, you can upgrade your boxed cake mix. Simply add an extra egg.

Along with adding moisture, the extra fat in the egg yolk will contribute richness and density to your cake while also strengthening the structure so it's easier to frost.

Since eggs can be hard to find right now, there are also alternative tweaks, such as replacing vegetable oil with melted butter, water with buttermilk, or both for added flavor.
