Mix all ingredients with a beater for 1 minute at a slow speed and then 2 minutes at medium speed. Pour the brownie batter in to the baking tray to create a sheet brownie. Bake at 180°C in a deck oven for 35-40 minutes. Once cooled, take the brownie out and slice into bars.
Mix well together, then fold in the 1000 g whipped dairy cream. Fill the silicone moulds and freeze. Once the mouse bars have frozen, place on the brownie.
Glaze with Decorgel Passion Fruit. Finally decorate with fresh fruit - we have used cranberries but other berries will work.
