Zucchini Brownies with Buttermilk frosting

Last year I discovered that not all zucchini brownie recipes are created equal.  When I went home recently, I found the zucchini brownie recipe that my mom used to make.  This is a delicious way to use up the giant zucchini that was left on your doorstep.

Mix together:
2 c flour
1 c sugar
1 tsp salt
1 1/2 tsp baking soda
1/3 c cocoa

Add to:
2 c grated zucchini
1/2 c oil
1 beaten egg (best at room temperature)
2 tsp vanilla
1/2 c chopped nuts

Bake in 9x13 pan 350 degrees 18-20 mins.  You can also bake in a jelly roll pan aka cookie sheet for a more flat brownie (baking time will probably need to be adjusted)

Frosting
Melt together in saucepan until boiling:
1/4 c butter
3 Tablespoons baking cocoa
3 Tablespoons buttermilk

Remove from heat and add:
2 1/4 c powdered sugar
1/2 c chopped nuts
1/2 tsp vanilla

Cool slightly and add to baked brownies  YUMMY!.
