How to make Halloween chocolate mousse
This is such an easy and fun Halloween dessert recipe to make for kids of all ages!
For the chocolate mousse
We use a really simple chocolate mousse recipe that comes together quickly. Just melt the chocolate chips in the microwave with half the cream. Then beat the rest of the cream with an electric mixer until stiff peaks form to make whipped cream. Then, gently fold the two together and divide it into small jars.
For the tombstone sugar cookies
Feel free to use your favorite sugar cookie recipe, or use the one we include in the recipe card below. Once you've made the cookie dough, roll it out and use a knife to cut it into tombstone shapes before you bake it. Writing RIP on top after they come out of the oven makes them look like they belong in a graveyard!
Tip: There will be more cookie dough than you need for the mousse so you can use it to make more fun and delicious Halloween cut-out cookies!
Full recipe instructions are in the recipe card below.
When stored in a sealed jar, the mousse will keep in the fridge for up to 3 days.
You can find oreo cookie crumbs in the baking section of most grocery stores. You can also use regular oreo cookies and crush them into small pieces to make a crumble.
You can make the mousse and the cookies up to 3 days ahead of time, but store them separately. Wait to assemble them until right before serving so the cookies and oreo crumbles keep their crunch.
