I loved it just served in a fancy bowl, or glass like that but am thinking it would be gorgeous pipped into those dark chocolate mini 'bowls' you can buy (I think some are vegan), as obviously dark chocolate and peanut butter is a match made in heaven ;) I was hoping it would make a great pie filling but unfortunately I think it's too floppy for that.
*Edit* Found some vegan dark chocolate cups at Sainsburys and the mousse is fantastic in these!! Looks cute too ;)Serves 3 - 4 (5 if using the chocolate cups)
150g soya whipping cream from a carton
75g super smooth peanut butter**
1/4 cup icing sugar
1 tsp vanilla extract
Chill the whipping cream then add the icing sugar and whip it up well. Whisk in the peanut butter and vanilla then spoon into serving bowls and chill for a few hours.
**a note on the peanut butter, I used sun-pat super smooth in this. I wouldn't recommend a 'natural' peanut butter unfortunately as you do need it to be sweet and really creamy, you don't want any graininess or separation. I know it's not the healthiest of PB's but this is a dessert after all ;)**
