What is the serving size of a fudge brownie this is important especially when you have a large group. The serving size per person of a chocolate brownie is 1 1/2 pieces each.

Let’s cover how we arrived at this calculation.

Most caterers, professional chefs, restaurants, and cafes will use 2×2 inches for the size of a standard brownie. The actual weight can vary a little bit depending on how thick you make your slab of chocolate brownies.

When you are serving a big group on average a guest will eat 1.5 dark chocolate brownies that are 2 square inches in size. This serving size will permit people to have some seconds. If you are really concerned that you have a group of big eaters or people who love chocolate then I would budget on serving two brownies per person of the standard size.

Another prototype when it comes to feeding a big group is to actually cut your brownies into half or even one-third sizes people will think and feel they are getting more because they will take two or three pieces each but really it’s only one 2 x 2 in.  brownie.
