Let’s Make it together
Prepare Your Ingredients: Start by gathering all ingredients on your countertop. Chop dark chocolate into small pieces for melting later. Preheat your oven to 350°F (175°C).
Melt Chocolate and Butter: In a heatproof bowl over simmering water, melt dark chocolate and butter together. Stir until smooth and shiny—this should take about five minutes.
Whip Egg Yolks and Sugar: In another bowl, beat egg yolks with half of your sugar until pale and thick—this takes about three minutes. The mixture should ribbon off your whisk nicely.
Add Melted Chocolate Mixture: Gently fold the melted chocolate mixture into egg yolk mixture until combined. Be careful not to deflate those precious bubbles!
Whip Heavy Cream: In a separate bowl, whip heavy cream until stiff peaks form—this usually takes around three minutes if your cream is cold enough.
Combine Mixtures Carefully: Finally, fold whipped cream into chocolate mixture gently but thoroughly. This step is crucial for that light mousse texture—we want airy clouds of happiness!
Now you’re ready to pour this luscious concoction into your prepared cake pan and let it chill in the fridge for at least four hours—or overnight if you can resist!
Enjoy every moment as you anticipate that first delightful slice of Chocolate Mousse Cake!
