Preheat the oven to 200C/400F and line a baking tray with grease proof paper/a silicone mat. While the oven is preheating, make the fruit topping: place the diced strawberries and halved raspberries and sugar into a small bowl and stir to coat. Leave to one side.
Cut the bread into 1 inch slices, place on the baking tray and brush lightly with the melted butter. Place in the oven for 4-5 minutes until golden all over. Leave to cool while you whip the cream.
Place the cream, sugar and vanilla extract into a medium bowl and whisk until it reaches somewhere between soft and stiff peak. You want it to hold its shape when you pull the whisk out of it, but be soft enough to spread.
Once the toasted bread has cooled, spoon a heaping teaspoon of cream onto each slice of bread and spread with the back of your spoon.
Top with 1tsp of the berry mixture, which by this time should have its own luscious sauce. Spoon a little sauce on top and let it run down the sides and serve! - If you're using bigger bread, you may need 1tbsp of cream and fruit per slice.
Berry Bruschetta is best eaten the same day, but you can keep it covered in cling film in the fridge for 1 day. You can make the elements 1 day ahead and then just assemble when required.
