I made the whoopies and they did turn out close to Cakeman's. I did notice in my research that the vinegar is left out of the whoopies. I'm not sure why, but I guess it is a structure issue. I found a recipe that resembled mine but looked closer to Cakeman's. I tweaked it a little, but if I were to make it again, I would do some more tweaking.
They are not as puffy as I would like, but the puffy ones didn't look as appetizing. Also, most reviews on RV stated that they did not puff even if the photo looked puffy. My guess is that the flavor suffers with more flour.
Some whoopies say don't double the recipe, but this one did fine.
Here is my change: Add about 1 to 2 oz more flour. An oz is about 4 tbsp. Next time I will add 2 oz more flour per single recipe. It may be able to handle more. When I'm doing these for a school project or for free, I'll try a little vinegar. I just didn't have time for a disaster tonight. I used my own cream cheese filling. I only added 3/4 oz of red food coloring. The volume of liquid in the coloring may be contributing to the spreading.
Pm me and I'll give you a link to my site. I will have pictures tomorrow morning.
Don't get me wrong, they are puffy. I just got my chocolate recipe to be super puffy and I would like for these to look similar. Tomorrow I will be boxing them together and they are really different.
I got 67 halves out of a triple recipe with a #40 disher (1 1/2 tbsp).
