I make this recipe often at my bakery as it is so versatile. I primarily use it in my Chocolate Peanut Butter Pie but I don’t stop there! Following are just a few of the desserts my shop creates with this mousse:

  • Use it as a filling for cakes – just let it set in the refrigerator for an hour and it will firm up so you can pipe with it.
  • Fill a parfait glass by layering chocolate ganache, bananas and peanut butter mousse. Top it off with a caramelized banana slice or peanut brittle for a little crunch.
  • Pipe it into mini-chocolate cups and drizzle with chocolate ganache for a Reese’s style treat.
  • For a gluten-free ‘cake,’ spread the mousse into a 9″ round cake pan, sprinkle peanuts and chocolate shavings on top, pop in the fridge for an hour and you will have a sliceable cake.

What type of peanut butter to use?

So many choices for peanut butter! Use your choice of chunky or creamy – I prefer texture in the mousse so I usually use chunky peanut butter. Be sure to mix the peanut butter well if using natural peanut butter so the oil and peanuts are homogenous.
