30 Tablespoons of baking cocoa

So apparently 30 tablespoons of baking cocoa is too much for a double batch of brownies. I was trying to make brownies from scratch to take to one of the ladies I visit teach who just had a baby. I decided to double the batch so that Quin could have a few brownies. The recipe called for 5oz of baking chocolate. I don't have baking chocolate, but on the back of the Hershey's baking cocoa it says that 3 tablespoons of baking cocoa and a tablespoon of oil equal a 1oz square of baking chocolate. So lets all do the math. 5oz x 3 tablespoons= 15 tablespoons. Now I was making a double batch, so of course 15x2= 30 tablespoons of baking cocoa. While I was scooping out the baking cocoa, I was thinking, 'Wow, this is a lot of baking cocoa.' But I am not the best cook, so who am I to argue with Betty Crocker and Hershey? When I was all done, I decided to try to make butter cream frosting. It was really lumpy and not fluffy at all like it usually is when I make it, so I thought, 'hum? I wonder if the brownies will be good enough without frosting?' Good thing I tasted them before I took them to the lady. They were awful! So dry and they tasted like I had eaten a spoonful of unsweetened baking cocoa. I guess if I cut the brownies into 30 squares, it would be like I had eaten a spoonful of unsweetened baking cocoa. I don't care what the recipe says, that is too much! Good thing Quin can cook or we would likely go hungry!
