FIFTH STEP: Combine remaining ¼ cup of cocoa powder and brown sugar and sprinkle over the batter.
SIXTH STEP: Pour hot water over the top of all ingredients.

NINTH STEP: Serve warm cake with ice cream if desired. Top with whipped cream and a cherry!
There is supposed to be a lot of sauce on the bottom. If you want yours less runny and more set up, use less water on the top. Cut ¼ cup water and see if it makes the consistency less runny.
Make this recipe ahead of time and store in the fridge. Just wait to add the hot water until right before you pop it in the oven.
Keep in mind that if you are adding some sort of harder candy like M&M’s, Reece’s, etc, they may sink to the bottom and become part of the sauce. Also, pulling the cake out of the oven halfway through baking could cause it to not set up correctly, so be aware of that too.
