You can totally leave out the toppings and mix ins and just put in choc chips to make ordinary brownies, its really up to you.
Adapted from here, this recipe will make a standard rectangular tray of brownies.
210 grams of butter (or margarine)
1 1/4 cups cocoa powder (I use the Cadbury brand)
1 1/2cups of sugar
3/4 cup of plain flour
3 eggs (take them out of the fridge the moment you need to add them)
2 teaspoons vanilla essence
1/2 teaspoon baking powder
pinch of salt
Note: You have to use plain flour and baking powder in this recipe self raising flour won't achieve the fudginess (it makes them rise them too much). You can skip the baking powder if need be but it makes them less dense.
Mix ins/toppings such as:
Chopped almonds (or other nuts)
Chopped chocolate bars - smartie, mint oreo, caramel (freeze first to make it less messy to chop up), cookies and cream, crunchie
Chopped/crushed Oreos - you can also put these whole in the middle for a fun surprise instead of on top
- Preheat oven to 180 degrees, line standard brownie pan with greaseproof paper and give it a spray with cooking spray (this makes a huge difference later on!).
- Melt butter (or margarine) in a largeish saucepan, mix in sugar, salt and cocoa powder, it will look grainy at this stage but don't stress! Let cool for 5 minutes (you don't want to scramble the eggs).
- Beat in eggs and vanilla essence until its glossy.
- Mix in flour and baking powder until there are no white streaks left.
- Stir in your mix ins reserving some for the toppings if desired.
- Pour into pan, sprinkle on toppings and bake for 20 minutes then check and lower the oven temperature to 150 degrees baking for another 10-15 minutes if required. It will be done when you insert a skewer and it comes out with crumbs clinging to it.
- Cool in pan and cut into squares and enjoy!
