Cake didn't show up in inventory after crafting

I crafted a cake, and it didn't show up in my inventory. It took my wheat, eggs, milk, and sugar, and gave back the buckets as usual, but I didn't get a cake. I had empty inventory slots, but I checked on the ground anyway, and it wasn't there. My cake disappeared! This has never happened before, and has not happened with any other items. Please fix this, I want my cake!
