It makes a world of difference in my opinion. I used to always have trouble with my cakes. I never knew how much they would rise. Sometimes they were really whimpy. I started using 1 tablespoon of Meringue Powder to each cake mix and the layers rise beautifully, each and every time. Everyone always remarks about how high the layers are.
I do this with every cake that I make, and it makes a big difference! I also use the bake even strips and don't have to trim much to get them level, so they stay high. I don't bake a cake without the meringue powder now! I found out by mistake once that it doesn't work if you add it after you mix either.
Yes, I tried this loooong time ago on a box chocolate cake and I was like Whooooooaaaa, not sooo high!!!!
Did it rise, yes or no?Make it simple for me , as my English is not too good.
