I just made this as a filling for a cake. I am pleased. I got the original recipe off of cake central, but had to alter it a bit.
1 - 3 oz package french vanilla instant pudding
2 TBSP powdered sugar
5 TBSP very hot water
1 tsp vanilla
1 cup heavy whipping cream
In a small bowl combine the pudding, powdered sugar, and hot water. Mix thoroughly in to a paste.
In a separate bowl beat together the vanilla and whipping cream until it forms stiff peaks.
Put a heaping spoonful of the whipping cream in to the pudding mixture and fold it in. Add the pudding mixture back to the bowl of whipping cream and beat together until thoroughly mixed.
This would be great in cupcakes, donuts, cakes, or with a spoon. ;)
