In a large bowl, combine the pancake mix, cocoa powder, and sugar. Pour in the cold water and mix until there's no visible flour left. Mixing more isn't better; it yields chewy pancakes.
Let the batter sit for 5 minutes.This helps the dry ingredients absorb the liquid, resulting in a consistent batter that yields great pancakes from start to finish.
Cook the pancakes:
Heat a large non-stick pan or griddle over medium heat. Once hot, grease it with oil, butter, or spray. Immediately pour ¼ cup of batter per pancake. Cook the first side for about 2 minutes. Flip the pancakes and cook the other side for a little less time. Avoid pressing down with the spatula; this makes pancakes dense.
Remove the pancakes from the pan and serve them immediately, or keep them warm, covered on a plate or on a sheet pan in a 200F oven while you repeat the process with the remaining batter.
Serve & store:
