Super Low-Fat Chocolate Brownies

Naughty but nice. Chocolate brownie is a comfort food, isn't it? Well..., why not once in a while! But I wondered if there was a good "guilt-less" chocolate brownie recipe. Then I found this! Chocolate brownies with mayonnaise which is called "ultimate makeover:chocolate brownies". MAYONNAISE in cake? I couldn't believe it, but I tried it for a laugh. They were really delicious. Noboby could guess there was mayonnaise in it. Very moist and light texture. Really chocolatey. The original recipe suggests using bicarb, but I use baking powder instead as I think the quiet taste of baking powder  doesn't affect the pure taste of chocolate.
I also used this recipe to make chocolate cake, and I just pour the mixture in a round tin to make a classy desert.
It's a great for a birthday cake for someone who loves chocolate, but is low-fat minded.

Ingredients

• 85g dark chocolate , 70% cocoa solids, chopped into small pieces
• 85g plain flour
• 25g cocoa powder
• ¼ tsp bicarbonate of soda (or baking powder which I prefer)
• 100g golden caster sugar
• 50g light muscovado sugar
• 1 tsp vanilla extract
• 2 tbsp Natural Yogurt
• 1 egg
• 100g “reduced fat” mayonnaise

Method

1. Heat oven to 180C/fan 160C/gas 4. Pour enough water into a small pan to one-third fill it. Bring to the boil, then remove the pan from the heat. Put the chopped chocolate into a large bowl that will fit snugly over the pan without touching the water. Sit the pan over the water (still off the heat) and leave the chocolate to melt slowly for a few mins, stirring occasionally until it has melted evenly. Remove the bowl from the pan, then let the chocolate cool slightly.
2. Meanwhile, lightly oil and base-line a 19cm square cake tin that is 5cm deep. Combine the flour, cocoa and bicarbonate of soda (or baking powder which I prefer). Using a wooden spoon, stir both the sugars into the cooled chocolate with vanilla and buttermilk. Stir in 1 tbsp warm water. Break and beat in the egg, then stir in the mayonnaise just until smooth and glossy. Sift over the flour and cocoa mix, then gently fold in with a spatula without overmixing.
3. Pour the mixture into the tin, then gently and evenly spread it into the corners. Bake for 30 mins. When a skewer is inserted into the middle, it should come out with just a few moist crumbs sticking to it. If cooked too long, the mix will dry out; not long enough and it can sink. Leave in the tin until completely cold, then loosen the sides with a round-bladed knife. Turn out onto a board, peel off the lining paper and cut into 12 squares.
