    I was looking for a cocoa powder based SMBC recipe and this is the only one I found, but it contains much less sugar and butter than other recipes online. Why is that? Also, is it stable enough to keep piped shapes in room temperature (up to 27C)?

      Hi Mario! The sugar and butter here are to be creamed and aerated so that the final buttercream is light and fluffy. Since the recipe uses cocoa powder, it is less “heavy” as compared to melted chocolate and thus do not need as much aeration. However, you could also increase the sugar and butter accordingly if you prefer that texture. It should also be stable enough to keep piped shapes in room temperature. However, that is also subject to the duration in which it is expected to hold its shape. Hope that clarifies!
