It is not surprising that the boundaries between cake and bread Washington Redskins the Legend of Taylor Heinicke shirt, biscuits, and buns are indirect. The ancestors of all have bread in their simplest form. As the technique of baking and evening developed, and the change in the pattern of food, what was originally considered as a roti, was seen as its own categories and named as according to it. Some Roman bread, which is rich in eggs and butter, have obtained daily stability and thus approached one of these indirect boundaries. Is the cake really hard and unable to eat? Then there’s nothing much you can do about it. The batter must have had less liquid to balance the dry out and/or it is overbaked causing loss of moisture rendering it really hard. Is the cake dense but not hard? In essence the batter was not flowing but not too solid either, then as Cris Smith mentions, it a different cake itself. In this situation, you can make trifle, or soak it in sugar syrup or chocolate syrup and serve with ice cream, or cut through in three layers to use it as a base for mouseecakes or cheesecakes.
In my place of work (a Pastry lab/culinary school north of Rome) we have a lot of scraps to work with, so I’ve had to repurpose cake scraps more times than I can count. You’re spot on about the trifle, it’s the perfect solution because trifles are great with even the stalest cake scraps (so long as there’s absolutely no spoilage to it of course). But we actually take it a step further. We work frequently with modern cakes, so there’s plenty of leftover creams, gels, and ganaches to choose from. I get to play around with combinations and prepare dozens of glasses full to serve to the various guests and students attending the school. In addition to this, as I believe one other commenter mention, we will make huge batches of cake truffles. Typically we add a good amount of rum to them so as to unify the various flavors and preserve freezer/shelf life. The truffles are a bit more involved to make so we typically make them only when we happen to have an overflow of scraps. If you’ve ever made cookies with a cookie cutter, you can imagine what kind of scraps would be leftover, all though, in this case, you can’t just ball up the scraps and reroll them.
