There's a week in July where 3 members of our family have a birthday, and one is a grandchild who, because of social distancing, will have two parties. I've a bit of time over the weekend and wanted to make the sponges for them all. Because it'll be mostly the same people, I'd like the cakes to seem different, so does anyone have a recipe that they tweak so I could make one go of batter and then separate it and add different things to it? I need some serious inspiration!
