MY WORLD FAMOUS BROWNIES

Yes, it sounds presumptuous, but I have been giving this recipe out for years as everyone who eats them asks for the recipe. It has ended up all over the world as it's shared with friends and family. So it IS world famous! And easy to make, which is always a bonus.
When you need a chocolate fix there's nothing better. Seriously.

SHELLE'S WORLD FAMOUS BROWNIES
125g butter
1 1/2 cups castor sugar
1/2 cup cocoa
1/4 teaspoon salt
2 eggs
1 teaspoon vanilla essence
1 cup flour [gluten free or wheat, depending who you're baking for]
1 teaspoon baking powder
250g chocolate chips [I always use dark, but use whatever you prefer]

Melt butter in a medium saucepan or microwave jug. Stir in sugar, cocoa, salt, eggs and vanilla, mixing well.

Stir through flour and baking powder. Stir through chocolate chips/pieces. The mixture will be quite stiff. Line an 18 x 28cm slice tin with baking paper. Spread brownie mixture evenly in tin.

Bake in a moderate oven [180C] for 25-30 minutes. Brownies will seem quite soft, but will firm on cooling. Leave in tin to cool completely [I put it into the fridge in the tin and cut it later - you get neater cuts when it's less gooey]. Cut into squares.
Store in refrigerator.
