Customizing Vanilla Cream Rolls for various dietary needs is quite achievable with a few thoughtful substitutions. For those who are lactose intolerant, you can replace the regular milk with almond milk or coconut milk, ensuring a dairy-free experience without sacrificing flavor. Additionally, you can utilize a dairy-free whipped cream alternative to prepare the Diplomate cream. If you need a gluten-free option, choose a gluten-free puff pastry available in several grocery stores. Lastly, to accommodate vegan diets, replace egg yolks with silken tofu blended with a bit of vanilla extract and a sweetener of your choice, while ensuring all other ingredients are plant-based. These adaptations assure that everyone gets to enjoy these scrumptious rolls!
