You know when you have those moments and you’re kind of in disbelief about how utterly brilliant you are? This was one of those moments.

I had seen way back when on Facebook a video of someone making whipped cream in a mason jar, just put shaking up some cream. And all of a sudden it hit me: you can make chocolate whipped cream by melting chocolate in cream, and then whipping it, and this is how a lot of people make mousse. Why couldn’t I melt chocolate in cream in a mason jar, cool it, and then shake it up into the easiest, most wonderful single serving dessert you’ve ever seen?

I could. And I did.

Now I wanted to be sure that I was actually utterly brilliant, so I did a quick Google search to see if this had been done like 100 times before. I found one video on YouTube, but it was a completely different recipe and other than that I found nothing else. And then I gave myself a pat on the back.

This is a super simple recipe to customize! You could add some instant coffee to the warm cream mixture for mocha, any extracts you love, use any kind of chocolate you love, mix in crushed cookies or candies or whatever you want!

If you’re making mousse for a crowd though, you’re probably going to want to mix it up with an electric mixer. Unless your company is into a little pre-dessert work out.

It takes a few minutes for the mousse to whip up and thicken, and you’re going to get a little arm work out in while you do it. You can use the exact same ingredients and whip with an electric mixer if you’re feeling lazy or you’re making a whole bunch!

    Hi Ashley! WOW…this is simply amazing! This is the best thing I’ve seen in a mason jar! I’ve had surgery on both elbows so I’m going to skip the work out and use the mixer.
