How Do I Stop Jam From Leaking Out of My Layer Cake?
You’ve done everything right. The cake layers are perfectly baked—level, tender, and fragrant. The vanilla buttercream is whipped to a silky, cloud-like consistency. The blueberry jam, glistening and jewel-toned, is ready to be the star of the show. You assemble your masterpiece with care, step back to admire your work, and then you see it: the dreaded bulge. A slow, heartbreaking ooze of jam begins to escape, turning your pristine creation into a sticky, unstable mess. It’s a moment of pure baking deflation.
