3/4 cup butter, melted
2 1/4 cups packed brown sugar
2 3/4 cups all purpose flour
2 1/2 teaspoons baking powder
1/2 tsp salt
2 cups semi-sweet chocolate chips
1 TBS vanilla extract
2. In large mixing bowl, combine butter and brown sugar; cool slightly. Beat in eggs, one at a time. In a separate bowl, combine flour, baking powder, and salt; add to sugar mixture and mix well. Stir in chocolate chips.
3. Pour batter into a 9x13 pan. Bake for 25 - 30 mins. When completely cool, cut into squares.4. These can seem gooey if you don't let them cool AND set. I actually think they taste best the next day or at least a couple hours later. If you over cook them, they will look done, but then they will set hard and crunchy. So, even if they seem a little gooey try and trust them :)
I hope they turn out as good as when my mom makes them... because they are gooooood :) These are seriously my #1 favorite baked good.
