Sheet Pan Brownies

Ingredients:
BROWNIES:
2 family-sized boxes brownie mix
1 stick butter, melted
4 eggs
1/2 cup water
2 cups semi-sweet chocolate chips

GLAZE:
2/3 cup butter
1/2 cup water
1 cup cocoa
2 tsp. vanilla
Dash of salt
4 cups powdered sugar

Preparation:
1. Generously grease a full-sized jellyroll pan or large cookie sheet with sides.
2. Preheat oven to 350 degrees.
3. Mix all ingredients together with wooden spoon.
4. Spread into pan.
5. Bake at 350 degree for 30 minutes, or until toothpick comes out mostly clean. Be sure not to stick toothpick into a chocolate chip when trying to determine doneness.
6. If glazing, make glaze 5 minutes before brownies are due to come out of the oven (glaze must be soft and somewhat pourable). To make glaze, melt butter in a medium saucepan over medium heat.
7. As soon as butter is melter, add cocoa, vanilla, water and salt and stir.
8. Add in powdered sugar, mixing with a whisk or hand mixer to achieve smoothness. (Alternately, put powdered sugar in bowl of stand mixer, then add butter and cocoa mixture and mix.)
9. Use glaze immediately, if desired.
NOTE: If glazing, score brownies immediately upon glaze setting up (before full hardening stage), but DO NOT cut brownies until they have cooled completely.
