How Do You Stop Jam Leaking From a Layer Cake

You’ve done everything right. Your cake layers are perfectly level, tender, and fragrant. The lemon curd is silky, the raspberry jam is vibrant. You carefully assemble your masterpiece, layer by layer, envisioning the beautiful cross-section and the clean, white frosting. Then, as you apply the final crumb coat, you see it: a faint purple or yellow streak, a tell-tale sign of a filling jailbreak. A few hours later, your pristine cake has unsightly bulges and weepy seams. It’s a moment that can deflate even the most optimistic baker.
