  2. In a separate bowl, whip heavy whipping cream until stiff peaks form using an electric mixer.
  3. Fold in 1/3 of the whipped cream into the peanut butter mixture in order to lighten up the batter. Then gently fold in the remaining whipped cream aiming to keep the fluffiness of the mousse.

Key ingredients

  • Peanut butter – The star of the show, you can’t have peanut butter mousse without peanut butter. Although you could substitute with your favorite nut butter, like almond butter or cashew butter and achieve a similar result. When selecting a peanut butter, make sure to use a creamy peanut butter instead of chunky (unless you want chunks of nuts in your mousse). Also look for a peanut butter that doesn’t contain added sugars. Ideally the ingredients should just say peanuts or peanuts and palm oil.
  • Cream cheese – Cream cheese is added to give this no-bake dessert structure, so you don’t end up with a floppy mousse.
  • Powdered sweetener – Added to sweetened up our dessert. Look for a confectioner’s sugar-free sweetener like erythritol, monk fruit or allulose.
  • Heavy cream – Whipped to form whipped cream. This is used to provide lightness and airiness to our creamy keto dessert.

    1. I think this is my favorite Keto dessert! I am a huge peanut butter lover: reeses pieces, reeses cup, peanut butter, you name it. I am new to Keto and this dessert is perfect to make my peanut butter craving dissappear! Before Keto my go to ice cream when I went to Dairy Queen was the Reeses Blizzard and this taste just like it! Sometimes I do it as a mousse and sometimes if I’m impatient I mix it all together and freeze it to make peanut butter ice cream. I even got my friends to try it next to the Reese blizzard and most of them couldn’t guess which one was Keto.
