So simple my kids make them all the time, easy to have the ingredients on hand all the time, and just plain really good brownies.
1 stick butter (4 oz)
2 oz unsweetened baking chocolate (2 squares)
1 cup sugar
3/4 cup all purpose flour
1 tsp vanilla
1 Tbsp powdered cocoa
4 oz kahlua liquor or 6 oz strong cold coffee
gently heat butter and baker's chocolate on the stovetop
add small amount of butter/chocolate to egg and stir to temper then add the rest then stir
add sugar, flour, vanilla, cocoa, and liquor or coffee - stir to combine
bake in 8X8" glass pan, preheated 350 degree oven ~17 minutes - more or less depending on your preference for chewy vs. more well done brownies
All the other people with the good stuff...
