1. Melt the butter gently in a sauce pan, on medium heat.
2. Add the Chocolate and stir till it’s completely melted.
3. At this point, you can add the nuts and stir in the vanilla.
4. Holding a sieve or sifter over the pan, put the flour along with the 2 tsps of baking powder in and sift into the chocolate mix. Stir mixed.
5. Turn down the heat to low and start adding the eggs one at a time and stir till each one is incorporated into the mixture. With each egg the batter should get smoother and glossier.
6. Turn off the heat and spoon the batter into sprayed mini muffin trays or regular muffin moulds. Fill each mould only 3/4th way full to compensate for the batter rising.
7. Bake in an oven pre-heated to 360F for around 12-15 minutes. When checking on the brownies it’s ok if the center is still a little sticky.
