Slutty brownies get their name because they are so easy to make and oh so naughty. Made up of a layer of cookie, a layer of Oreo cookies and a layer of brownie, it doesn't get much more indulgent than this!
Generally they are made with cookie and brownie mix but I much prefer to make it all from scratch. I adapted one of my favourite cookie recipes which I got from Jo Wheatley's book A Passion for Baking and I took a Brownie recipe from here and adapted it slightly.
Start off making the cookie batter
100g peanut butter (I use crunchy but you could use smooth)
60g demerera sugar
60g caster sugar
100g plain flour
1/2 tsp baking powder
1/2 tsp bicarbonate of soda
60g dark or milk chocolate, roughly chopped
Grease a square cake pan. My pan is approx 8x9 inches and was perfect size.
Beat the margarine, peanut butter and both sugars together until flight and fluffy. Beat in the egg. Add the flour, bicarbonate of soda and baking powder and mix until combined and the dough comes together. Add the chocolate last.
Pop the cookie batter in the cake pan and bake for approx 20 minutes in an oven at 180ºC, 160ºC fan oven, Gas Mark 4. You want the cookie batter to be baked, even though it's going to go back into the oven it won't be overcooked and will stay gooey.
While the cookie is baking the oven you can start on the brownie mix.
You will need:
140g plain chocolate
225g caster sugar
1 tsp vanilla extract
40g plain flour
1 tsp baking powder
25g cocoa powder
55g creme fraiche
200g peanut m&ms (frozen)
First, melt the margarine and chocolate over a bain-marie. In a seperate bowl whisk the eggs, sugar and vanilla together. Stir in the melted chocolate and whisk. Whisk in the flour, baking powder and cocoa powder. Add the creme fraiche and one third of the m&ms.
Once the cookie is ready, remove from the oven and turn the oven down to 170ºC, 150ºC fan oven, Gas mark 3. Now lay the oreo cookies on top of the cookie before adding the brownie mix.
Sprinkle another third of the m&ms on the top before putting in the oven.
Leave in the oven for another 20-25 minutes.
Leave to cool thoroughly on a wire rack before removing from the pan and cutting into squares.
This makes 12 generously sized brownies. I like them enough just on their own but you may want to eat them warm with ice cream mmmm.
