Ingredients for chocolate mousse pie

It all begins with homemade chocolate mousse, which couldn’t be simpler.

1 Diamond of California prepared walnut pie crust
semi-sweet chocolate, either chips or chopped
unsalted butter
water
egg yolks, room temperature
granulated sugar
pure vanilla extract
instant espresso powder

I like to top my pie with homemade whipped cream. For that, you’ll need the following:

heavy cream
confectioner’s sugar

How to make no-bake chocolate mousse pie

This pie wouldn’t be ‘no-bake’ if I had to make the crust myself. Instead, I reached for a walnut pie crust from Diamond of California, one of their new Ready-to-Use Nut Pie Crusts that recently hit markets. Instead of cookie crumbs, the crust is made from tree nuts! These crusts are made with 10 ingredients or less, and are a more nutritious way to pie than traditional cookie crusts.

Oh yeah, and also they’re delicious! And given that walnuts are the main ingredient in this crust, I know it would be perfect in savory preparations as well.

Once you’ve got your Nut Pie Crust, make chocolate mousse!

First, dissolve instant espresso powder in a small bowl with vanilla extract (or water).

To make chocolate mousse, combine chocolate, butter, and water in a microwave safe bowl. Heat in 30 second increments, stirring after each addition, until smooth.

Next, combine egg yolks, sugar, and instant espresso/vanilla in a small sauce pan over medium-low heat. Whisk until thickened, about 3 minutes.

Add the egg mixture to the chocolate, then stir until well combined. Place in fridge.

Finally, whip half of your heavy cream with confectioner’s sugar until stiff peaks form. Gently fold into the cooled chocolate mixture until no streaks of cream remain.

Assembling chocolate mousse pie

Once you’ve made your homemade chocolate mousse, simply pour into Diamond of California walnut pie crust, smooth the top, then refrigerate until set, about 2-3 hours.

When ready to serve, top with homemade whipped cream and chocolate shavings.

Is this pie gluten-free?

The Nut Pie Crusts from Diamond of California are not gluten free. They’ve replaced 3 ounces of flour and sugar with 3 ounces of nutritious Diamond nuts. A small amount of wheat flour is included in the ingredient list to help keep the crust together without having to rely on processed stabilizers and guar gum.

The remaining ingredients in this chocolate mousse pie are gluten-free.

How long will mousse pie keep?

This pie can be made up to 2 days in advance. Cover and refrigerate until needed, then whip the cream day-of and top the pie right before serving.

Can you freeze mousse pie?

Yes! Fill the prepared Nut Pie Crust with chocolate mousse, then cover with plastic wrap and aluminum foil. It can be frozen for up to 3 months. To serve, thaw completely in a refrigerator overnight, then top with fresh homemade whipped cream and chocolate shavings just before serving.

Can I switch out the filling?

Yes! This would be SO delicious with either peanut butter mousse, strawberry mouse, or even pumpkin mousse for Thanksgiving!

All I know is that having a no-bake pie in the lineup for your busiest holidays — shoutout to Thanksgiving and Christmas! — will make executing your vision SO much simpler.

Seriously, this pie is epic. And you better believe we licked the pan clean!

You can pick up these new Ready-to-Use Nut Pie Crusts by Diamond of California at Walmart, Save Mart Supermarkets, and H-E-B Texas Grocery. Trust me, you need these in your life!
