My Favorite Holiday Recipe

Okay, here goes. I have alot of favorite recipes because I am a baker a Christmastime. Every year I have a Holiday party with my closest friends and their husbands and I bake for weeks and weeks (don't worry, I freeze everthing to keep the mold off!) and then everyone eats until they are as full as they can be. Probably the most asked for recipe is my brownie recipe. I have to say (she said modestly) that they are the best I have ever eaten. So you can try them and let me know if I am right! I must warn you, make the frosting. It is the key to their greatness. One of my friends calls me every month when mother nature visits and begs for these brownies. They are POWERFUL!
Karen's Brownie Recipe
Preheat oven to 350.
1 cup butter
2 cups sugar
1 cup flour
2/3 cup cocoa powder
1/2 tsp baking powder
2 eggs
1/2 cup milk
1 1/2 tsp vanilla
1 cup semi sweet chocolate chips
Stir ingredients together by hand until mixed.
Grease a 13X9 pan. Cook for 30 minutes or until brownies pull away from side of the pan. DO NOT OVERBAKE! These are gooey brownies, not cakey brownies.
Let cool and then frost.
Frosting
Sift one package powdered sugar (about 4 cups). Melt 1 stick butter in saucepan, add 4 tablespoons cocoa powder and 1/3 cup whole milk (no substitutes). Heat until mixture is free of lumps and extremely hot, almost to a boil. Remove from heat. Add powdered sugar and stir. Mixture will be liquid enough to pour over brownies and spread with a knife. Let cool until frosting hardens. Enjoy!
