This mousse is a little rough looking, but what it lacks in appearance it more than makes up for in taste and texture. It’s like peanut butter, but in satin pillow form. Start by placing your soft butter in a mixer fitted with a paddle.
Beat until smooth and light in color, about a minute. Then add the peanut butter and beat about three minutes until perfectly smooth and even.
Scrape the mixture into a large bowl. Wash and dry the mixer bowl.
Whip your cream to stiff peaks and fold it into the peanut butter mixture.
Done! There, wasn’t that easy? This stuff is great for filling cakes, or just eating, ideally our of some edible chocolate cups. It will hold for several hours at room temperature, but pipes best after it’s just been made and is still slightly cool.
