In a large, flat bowl, shake out about a 1/2 cup of the cocoa powder (I like to mix half and half dark chocolate baking powder and hot cocoa mix). Scoop 1-2 Tbsp of chocolate out of the bowl and roll it between your hands until it forms a nicely rounded sphere. The chocolate will feel sticky on your hands as you roll it–that’s OK. Once each sphere is formed, roll it around in the bowl of cocoa powder, until it is well coated and no longer sticky.
