Chocolate Mousse Brownies | Creme de la Crumb

Happy Sunday! Sunday is my favorite day. As a kid I hated Sunday. But as an adult? Love it. I may change my tune in a few weeks when our twins arrive (6 weeks actually. how on earth did this happen???) but for now Sundays mean lazy mornings in bed, a few uplifting hours at church, and crazy family dinners where I am reminded just how unlike my family I am but just how much I love them.

Another thing I love about Sundays though? Dessert. Sunday ALWAYS includes dessert. We’re lucky enough to live close to both of our families and if it’s not homemade pineapple ice cream at one house, it’s some kind of chocolatey confection at the other. And if we’re being entirely honest here, sometimes it’s both. For the sake of not wanting to upset the mother-in-laws ya know?

That brownie layer on the bottom half is dense and chewy and fudgy and perfect. On top of all that goodness you’re falling in love with that creamy rich layer of chocolate mousse. It’s pure heaven I tell ya.

Heaven.

Ingredients

  • 3/4 cup flour
  • 1/2 cup cocoa powder
  • 1/2 teaspoon salt
  • 3/4 cup butter
  • 1 1/2 cups sugar
  • 1 teaspoon vanilla
  • 2 eggs

Mousse layer

  • 3/4 cup mini marshmallows
  • 3/4 cup semi-sweet chocolate chips
  • 1/4 cup milk
  • 1 cup heavy whipping cream

Instructions

  • Preheat oven to 350 degrees. Line a 9x9 inch square pan with nonstick foil and lightly grease.

Hi jow long does this choco mousse recipe last? Room temp and ref thanks

It says to add heavy cream to make the mousse, is that supposed to be the heavy whipping cream?

    Yes, heavy whipping cream. 🙂

Why you used marshmallow instead of gelatin? Which is better?

Is the foIl necessary? If yes, when do you remove it?

    It’s for the ease of cleanup. It is removed when you slice the brownies to serve.

The fLavor was amazing, but my brownie layer WASN’T very Gooey or fudgey, mOre cake Like and a bit dry. The mousse made up for it!

    Interesting! Sorry to hear that. I haven’t had that issue. Thanks for sharing, Laurie 🙂
