Low Calorie Chocolate Brownies

I have to share this recipe, because it is amazing! The best brownies I have ever tasted, and only 91 cals per piece. The secret ingredient here is extra-light mayonnaise. (Tell people about it and they won't touch, more for you!)

Ingredients 

• 85g of your favourite chocolate

• 85g plain flour
• 25g cocoa powder
• 1/4tsp bicarb soda
• 100g caster sugar
• 50g light brown sugar
• 1/2tsp coffee granules
• 1tsp vanilla etract
• 2tbsp 0% fat vanilla yoghurt
• 1 egg
• 1tbsp warm water 
• 100g extra-light mayo

Prep

• Preheat oven to 180c or 160c if you have a fan oven
• Grease & line a 19cm square tin
• Mix the flour, bicarb soda, and cocoa powder in one bowl
• Mix caster sugar & brown sugar in bowl no.2
• Mix coffee, vanilla, & yoghurt in bowl no.3

Recipe

• Melt the chocolate (in the microwave is easiest)
• Stir the sugars into the chocolate
• Add the coffee/vanilla/yoghurt mix
• Stir in 1tbsp of warm water
• Beat in a whole egg, make sure it's well mixed
• Stir in the mayonnaise
• Gently fold in the flour/bicarb/cocoa mix, being careful not to overstir 
• Pour into your lined tin, and smooth out evenly
• For those of you who aren't watching your waistline, here comes the fun part - you can add chocolate chunks, walnuts, sweets, anything you like. Just push them gently into the top of the mix, dotted around.
• Put in the oven for approx 20-25 minutes.

  

• To check when they're done, stick a cold knife into the middle, if it comes out with a few sticky crumbs it's done, if you like them more gooey then take them out when there's lots of sticky crumbs.
• Let them cool down on a cold surface, they will get slightly dryer as they get cool so don't panic if you think you've taken them out too early.
•  Slice them into 12 slices, and eat!
