Hi Ginny,
If your sister likes coconut you could try a mixture of unfiltered coconut oil (which is quite solid at room temp) and some mild tasting and softer fat to replace the butter. I would imagine melting the coconut oil and blending it with a nut oil then letting it come to room temp would work) great. The coconut oil smells heavenly and some toasted shredded coconut would be a fantastic decoration addition to up the flavor. Just remember to have a warning next to the cake to possible nut allergy folks (had a close call at my own sister's wedding
Good luck! You are a good sister for doing this :)
