You cut into the beast, and now there’s an exposed slice missing. This is where a sliced cake needs extra love. Press a piece of plastic wrap directly onto the cut side. This is called “contact wrapping,” and it stops the exposed crumbs from drying out.
Then, wrap the whole leftover slice or half-cake the same way you did the whole cake. That cut edge will stay moist, and you won’t end up with a sad, crumbly wedge tomorrow. It’s like a little bandage for your cake’s wound.
If you’re feeling fancy, you can also use wax paper or parchment between the cake and the plastic wrap for nonstick protection. But honestly, plastic wrap alone works like a charm if you’re gentle.
