What are Hilary Erickson's signature techniques for enhancing boxed cake mixes?

Hi, I’m Hilary Erickson from The Pregnancy Nurse.

When I’m “doctoring” a boxed cake mix to make it taste more special, I usually:

• Swap melted butter for the oil
• Use milk instead of water
• Add an extra egg or two for richness

Those simple changes make the texture a bit more like a from‑scratch cake, even though my kids mostly just care that there is cake.

Are you making a particular flavor or theme for this cake?
