After trying several other recipes, and several failures, a friend of mine showed me this one. It worked! HUZZAH!
I made ONE batch. Then I piped out half of the batter onto a silicone mat & perforated baking sheet. The other half I piped out onto a regular baking sheet, with parchment paper. I let them sit for the same hour. I placed them in the same oven. I pulled them out at the same time. The difference is AMAZING. I highly suggest getting a silicone mat & perforated baking sheet for making these. The parchment paper tray turned out cracked & hollow. The silicone mat & perforated baking sheet ones came out PERFECT, in my opinion. (granted, they aren't quite as "poofy" as other ones I've seen online. And the feet are small, but they are there. So for now, I'm putting this in the win column.)
