Beating the egg whites is the answer to the denseness that comes with making an almond flour bread. I’ve made countless baked goods using almond flour and the main problem I’ve encountered is how dense the finished product is. The fluffy egg whites in unison with the high dosage of baking powder do a good job of getting this loaf nice and fluffy and adding some air pockets into the loaf. This makes for a better tasting bread.
I have not tried this yet. It could work, if you baked it for longer. The only thing I’m worried is that it might not rise as much because of the extra weight. I might be wrong, but I don’t want you to be upset about waisting expensive ingredients. There’s someone who commented about doubling the recipe on october 25th 2018 – but it sounds that she might have used 2 pans instead … here’s the comment: “I just made this. I doubled the recipe and used long narrow Wilton pans. I used carton egg whites. I baked it for 45 minutes, turned the oven off and left it closed for 30 minutes. Awesome, awesome, awesome!!! I now have 21 slices of bread in the fridge to experiment with. (That means I already ate 3)”
