Chocolate Cream for Cake Filling

[SHA]

This is the ingredient list for a chocolate cream cake filling and I could use some help in translating this into a home baker's version (not sure what to substitute for the cocoa paste and dessert cream powder):

Chocolate Cream :

butter

chocolate

cocoa paste

dessert cream powder (sugar, modified starch, fat-reduced cocoa, glucose syrup, palm fat, emulsifier E472b, milk protein, thickener – corrageen, maltodextrin, flavoring)

For a home baker's version, you can substitute cocoa paste by melting extra chocolate with a small amount of butter to maintain the consistency. For the dessert cream powder, create a mix by combining powdered sugar, cocoa powder, a small amount of cornstarch (as a thickener), and a pinch of salt. Adjust the sweetness and consistency to your liking.
