What can you substitute solid vegtable shortening with in a cream filling?

You can substitute solid vegetable shortening in a cream filling with unsalted butter for a richer flavor, keeping in mind that it may alter the texture slightly. Alternatively, you can use coconut oil, which offers a similar consistency, but will impart a subtle coconut flavor. For a non-dairy option, consider using margarine or a plant-based shortening. Adjustments in sweetness or flavor may be necessary depending on the substitute used.
