Chocolate Mousse Cake Filling Recipe

Chocolate Mousse Cake Filling only needs a few ingredients to make the creamiest mousse ever. Great by itself or on top of a cake!

This is the easiest recipe for chocolate mousse that you will find. Not only is it quick to prepare, and you only need a few ingredients, but it’s unbelievably rich and creamy.

I technically made this as a filling for chocolate cupcakes, so it’s a chocolate mousse cake filling, but you could honestly eat this as a dessert all by itself.

For these photos, I spooned it into margarita glasses, and topped it with a single blackberry, and it made for a really pretty and simple dessert!

With a pile of berries on top, or a dollop of whipped topping, this makes for a really elegant dessert.

I think you could fill shot glasses or shooters with this mousse and a little whipped topping, and they would be fabulous mini-desserts for parties and entertaining! This quick recipe comes to the rescue and gives you a simple dessert in minutes.

But the original reason I made this chocolate mousse cake filling was to fill the center of dark chocolate cupcakes. And they were sublime.

Imagine sinking your teeth into a moist and rich chocolate cupcake, and you are met with this delectable fluffy and chocolate-y treat in the middle. 

I actually haven’t shared the whole cupcake recipe yet, so you’ll have to stay tuned for the completed dessert, but chocolate lovers will not be disappointed!

To prepare this mousse, you only need one bowl, a handful of ingredients, and a microwave. It’s a cinch whip up!

I combined milk with semi-sweet chocolate, and heated them until the chocolate was melted and smooth, creating somewhat of a ganache!

I mixed in instant coffee granules because the coffee gives so much extra richness and dimension to the chocolate.

It’s not overpowering in flavor so that this tastes like a mocha dessert, but it definitely magnifies the richness of this mousse.

I stirred in chocolate pudding mix for more chocolate-y goodness, and then mixed in whipped topping so that it was light and fluffy!

It’s the perfect filling for cakes and cupcakes, and it’s delicious all on its own too!
