FAQ
Can I use frozen blueberries instead of fresh?
Yes, but thaw and drain them first to prevent excess moisture from making the crackers soggy. Pat dry with paper towels before layering.
How long does this cake need to set?
Minimum 4 hours for pudding to set and crackers to soften slightly, but overnight is ideal for best texture and clean slicing.
Can I freeze leftover cake?
Not recommended as the texture changes significantly when frozen. The pudding and Cool Whip separate and become watery when thawed.
