I forgot the oil in my apple cake.

3 c flour
2 c sugar
1 tbsp baking powder
salt, cinnamon, vanilla, etc...
1/3 c apple juice
4 cups chopped apples
1/2 c each raisins and walnuts

Supposed to have 1 cup of oil.

It took the usual amount of time to bake and looks normal. But is for a customer so I can't cut it. What do you think?

Hmm. If it's a rectangle cut off the edge deep enough like a scant inch to determine how it's gonna be inside. If it's a round, I'd cut it in half just off center and then move the knife just past center and just cut a bit and cut off a tid right through the middle so you can be sure--but not an inch wide that would take too much out. You might have to chill it to do this. Use a hot knife, clean it for each cut so you don't rip it to shreads trying this.

Then sandwich it back together with icing. I mean if it isn't any good you gotta make another one. If it will pass you can still salvage it. I mean not knowing would kill me.

That's what I would do. You might be able to get away with using it. Or it might be rubbery or it might crumble. I would have to cut it.

Apple sans oil cake thoughts for you.

Fat in a cake recipe contributes tenderness, moistness and a smooth mouth feel.

I think I would rebake.... Your reputation is on the line with this customer.
