(one's) cake is dough
One's actions have failed or not led to the desired outcome—much like a cake that is still dough after baking. The phrase appears in Shakespeare's The Taming of the Shrew. I know you worked really hard on this project, but it looks like your cake is dough, and you won't be winning the contest.
