Boysenberry & toblerone brownie

Thanks to Healthy Food Guide NZ for the recipe!

3 eggs, seperated
1c castor sugar
3/4c low fat vanilla yoghurt (I used Meadowfresh Live-Lite because I had it in the fridge, Vanilla Spice and Vanilla Toffee)
1 1/2 tbsp vegetable oil
1 1/4 c self-raising flour
3/4c cocoa powder
1/2c frozen berries (recipe used raspberries, I used boysenberries and cut them in half)
50g toblerone, cut the triangles in half

-  Preheat oven to 180 deg C, line a 30x20cm baking tin with baking paper
- Combine egg yolks, sugar, yoghurt and oil in a mixing bowl.
- Sift in flour and cocoa and mix well.
- In a seperate bowl beat the egg whites until they form soft peaks.
- Fold in to the other mixing bowl (make sure you fold it in! Otherwise it takes ages for them to mix!)
- Pour mixture into the baking tin and spread evenly with berries and toblerone
- Bake for 20 mins or until skewer comes out clean
- Cool completely before removing from tin and slicing.

The texture is absolutely perfect - but more like cake than brownie (I may have over-baked it) - not as fantastic tasting on it's own as the last brownie I blogged about but the toblerone (I didn't get any berries on my slice) really completed it. Not too sweet, not moist or dry, but don't make this recipe unless you are putting stuff on top!
