Tip - Nutella can be made Easily Spreadable
Ever since I began making Chocolate Babka there has been a problem getting the Nutella thin enough to easily spread on the raw bread dough before rolling up.
Google has a number of methods that claim to work and I’ve tried a bunch of them.
The simple solution to thin Nutella is to slowly add very small amounts of water to the chocolate spread. This technique will make the mixture as thin as you desire. It will also maintain this viscosity for an extended length of time if the product is kept sealed.
