Melt the butter and ¼ cup of chocolate in a microwave safe bowl and mix until its fully melted.
Add in the confectioners' sugar, egg and vanilla, mix
Add in the dry ingredients and then add 2 tablespoon of chocolate and stir it in until it's just combined.
Line a loaf pan with parchment paper or if you don't have parchment substitute with aluminum foil. Spread and even out the brownie batter and bake for 15-18 mins.
You can stick a toothpick into the brownie after 15 mins and if there are just a few crumbs take it out. If it's wet, then bake for a couple of minutes and then check again.
Once the brownies are done let them rest and cut when cooled.
