Okay, they're in the oven. I preheated the ramukens, set the oven to 325°f instead of 350, weighed my eggs and mixed with a spoon this time. Turns out my quail eggs are a bit shrimpy and 2 eggs came out to 27 grams insteads of the 28-31 I was looking for. So I took the three smallest ones I had that came to 34 grams and removed 3 grams of egg white to equal 31 grams.
I actually just finished another batch that went perfectly. I got some advice to preheat my ramukens, weigh my eggs, bake at a lower temperature and stir with a spoon instead of beaters. They didn't sink at all and even have a bit of that shiny crust on top like boxed mix. I haven't gotten that shiny crust with homemade brownies before so I am quite pleased.
