Yes it is! Erima, thats correct. According to Niska and PrimaCakesPlus, you can use lemon juice or vinegar along with milk. You will get a lighter/moist cake.
In addition some other great baking tips are sifting your flour about three times. Lift your sifter a bit high when sifting to incorporate more air. Also, depending on the cake recipe(s), you can add oil for a more moist cake and before covering your cakes with fondant, you can mix water and sugar together and a flavouring of your choice, probably in a squeeze bottle and randomly squeeze over your cake(s).
The foregoing and more are great tips for cakes. Cake baking and decorating is also like an adventure and we learn nearly everyday, via other decorators, online, bakers etc as we go along. I hope I was of help to you.
