Melt the butter and 1/2 cup of chocolate chips in the microwave for 2 minutes. When it is done, stir the melted butter and and chocolate until they are one mixture.
Add the egg but be sure to stir it right away( or else the egg may cook. I also suggest using a fork.).Stir in the sugar.
Add the baking soda, baking powder, salt, and flour and stir it all.
Fold in the chocolate chips.
Preheat the oven (I used a toaster oven since our big oven is broken so you may have to change the cooking settings) to 350 degrees. Oil/spray the cookie sheet. Roll the dough into about 1 inch diameter balls and place them atleast 2 inches apart because these cookies expand as they bake.
Bake them about 5-6 minutes (i used a toaster oven so it may vary for your oven). Then take them out and let them cool on a cooling rack or on a plate (doesnt matter - i did both since my cooling rack is small).
