Well, sometimes you can't always "think outside the box" on some recipes. However, being trained to make everything from scratch, I would STILL play with the recipe and find a way to make it from scratch, (fresh squeezed lemon juice), Swansdown Cake Flour and the other essentials for a good cake.
Wow! ..hmmm...good!
I will be posting a recipe each week from various sources that have been hits for different events.
