Ingredients:

800g butter
800g plain chocolate
200g milk chocolate
12 medium eggs
1kg sugar
450g sieved plain flour
2 tsp salt
2 tsp vanilla essence
2 tbs baking powder

Some goodies to put in and decorate the brownies with: I used mars bars, marshmallows, fudge sticks, caramel, mint and popping candy bars to give an explosion of taste.

Estimated cost £12 upwards (depending on what ingredients you want to put in your brownie!)

Step 1: Melt 800g butter and 800g plain chocolate together

Step 2: Beat 12 medium eggs and 1kg sugar together until pale in colour and light in texture - about 8 mins using an electric whisk should give you a real nice cracked flaky brownie top once cooked

Step 3: Pour butter/chocolate mix into the egg/sugar mix and fold until blended. Add in 450g sieved plain flour, 2 tsp salt, 2 tsp vanilla essence, 2 tbs baking powder and the goodies you want to pack the brownie with. (This is where I had to divide the vast amount of mixture into two bowls as I didn't have one huge bowl that was big enough)
