- STEP 1
Preheat the oven to 190degrees (fan) Mix together the carob powder, flour, sugar and baking powder in a large bowl. In a separate bowl, mix the water, milk, eggs, oil and mashed bananas. Pour the wet into the dry ingredients with the vanilla extract and mix thoroughly.
- STEP 2
Now add the chopped walnuts if using them. You could also add dark chocolate chips if you wish. At this point, if the mixture is too thick, add a little extra milk until it is looks thick but stir-able.
- STEP 3
Transfer the mix to a greased, non-stick brownies tray (could use baking parchment but I didn't seem to need it).
- STEP 4
Cook in the preheated oven for around 20-30 minutes - the brownies will feel firm to the touch, not wobbly like normal brownies.
