Cocoa powder for the most intense chocolate flavor ever! And there's no added sugar, since buttercream is already super sweet, not to mention it's so cheap versus using real chocolate!
Combine the cocoa paste with the hot boiled water in a small bowl & whisk smooth. Set aside and cool completely at room temperature
Place the vegan butter & salt in the work bowl of your electric mixer with the paddle attachment & whip on medium to high speed for about 3 minutes.
Scrape the sides & bottom of the bowl then add the sifted confectioners sugar all at once.
Mix on low speed until incorporated then scrape the bottom & sides of the bowl again & mix on medium to high speed for another 3 minutes.
Add the extracts & the cooled cocoa paste while mixing on low, then turn up to medium high speed & whip smooth for 30 seconds
