I see this is made in Rome, Georgia. They probably use a flour grown in the South, similar to White Lily, which is a low protein all-purpose flour similar to cake flour.
If you can’t find a low protein Southern all purpose flour, I would use a cake flour (which is similar) in making the pancakes. That would contribute to a cake like texture rather than a bread like texture.
Like I said, it’s probably the the flour they are using in the mix. Use cake flour. It also has cornstarch, which would contribute to cake like texture and lightness.
The best option is to “make” the cake flour. Just switch out one tablespoon of flour with cornstarch per cup of flour, then whisk it together.
Taking out all the chemical names, the ingredients look like:
flour (Southern low protein all-purpose flour, or substitute cake flour, or cornstarch and all-purpose flour)
yellow corn flour (cornstarch - like Argo & Kingsford’s brands, etc)
shortening (soybean oil)
powdered milk?
dried buttermilk
sugar
baking soda and baking powder
salt
dried egg yolks
