Brownie cake with chocolate mousse – tips

I made this brownie with dark chocolate mousse for my husband’s work and the cake received only praise.

That’s why I’m rushing to share the recipe with you :)

I made the cake just before the holidays, but I ran out of time to write the recipe here.

It’s a bit of a shame, because this brownie would be perfect as a chocolate mazurek :)

Here we have a simple chocolate base – made without baking powder (as in brownie) and an extremely delicious and rich chocolate mousse.

For the chocolate mousse itself, I used dark chocolate and didn’t add any sugar.

For some time now, I’ve loved chocolate creams made with dark chocolate, softened only with heavy cream.

Such a mousse is very intense in flavor, but not bitter.

Heavy cream softens the strong flavor, and the mousse gains incredible depth.

If you like dark chocolate, you will also love such a chocolate mousse – be sure to try it!

The holidays are over, but you can make this chocolate cake with chocolate mousse for the weekend.

It will be perfect with coffee :)

How to make brownie with chocolate mousse?

First, prepare the brownie.

I made it entirely in a pot.

First, I melted butter in it, then added the remaining ingredients and mixed with a spoon.

This is probably the simplest and fastest brownie recipe :)

Once the cake was baked and cooled, I prepared the chocolate mousse.

I melted the chocolate for the mousse in a double boiler and then mixed it with whipped heavy cream.

If you prefer sweeter cakes, you can use milk chocolate instead of dark.

Then add a little more gelatin to the mousse – about 1.5 teaspoons.

I hope you like this brownie with chocolate mousse recipe and make use of it.

Also check out my other chocolate cake recipes.

I recommend, among others, brownie with cream cheese or brownie with Nutella.

You will also find many delicious chocolate recipes in my chocolate e-book – I highly recommend it!

Brownie with Chocolate Mousse Recipe

This chocolate mousse brownie cake is a wonderful idea for a weekend treat. A simple brownie recipe made in a saucepan and stirred with a spoon—anyone can make it. Because this baking powder-free chocolate cake always turns out perfectly! Originating in the United States, the brownie is a highly popular, intensely chocolatey dessert. Made with real chocolate or dark cocoa powder and no leavening agents, it is dense, heavy, and delightfully fudgy. And that is exactly how it’s supposed to be! Here, I prepared an express cocoa brownie and let it cool without removing it from the baking pan.

Brownie Cake Recipe

For this brownie, I made a dark chocolate mousse. This made my chocolate mousse brownie mega chocolatey and intense in flavor. I used just under a cup of sugar in the entire cake, so it wasn't overly sweet. The mousse itself is made with no added sugar at all! It is deeply chocolatey and rich. It’s a true treat for lovers of intense chocolate desserts. No one will be able to resist a slice of this chocolate mousse brownie.

Brownie Cake Recipe

Take a look at my chocolate mousse brownie recipe and see how to make a quick brownie. This brownie served with mousse looks like a million bucks, and you can easily serve it on a holiday table or prepare it for a family celebration. The chocolate mousse sitting on top of the thin brownie base looks absolutely stunning. In my opinion, it could easily be served as a chocolate mazurek (a traditional Polish Easter flat cake). I know I would gladly eat a mazurek like this!

If you love chocolate cakes and brownies, make sure to check out my other chocolate cake recipes as well. You will find plenty of inspiring ideas there. Personally, I highly recommend my delicious halva brownie, coffee brownie, or blueberry mousse brownie. But for now, head over to the kitchen and get to work. Treat your family to this heavenly delicious chocolate mousse brownie today. I am absolutely sure everyone will love it! Let me know just how thrilled they were :)
