These are an absolute favorite from my childhood. They are melt-in-your-mouth delicious! I can't even describe how good they are, you have to taste them. Don't be overwhelmed by the frosting, it actually turns into the most delicious of glazes.
For brownies: In a large bowl, cream sugar and butter together. Add eggs one at a time, stir. Add syrup, mix well. Add flour, mix well. Pour into a greased cookie sheet with 1" sides. Bake at 350 for 25-30 minute.
For frosting: Meanwhile, in a medium saucepan, heat sugar, butter, and evaporated milk. Bring to a boil, allow to boil for 30 seconds. Remove from heat, stir in chocolate chips, mix well. Frost brownies as soon as they are removed from the oven.
