How to Make Dulce de Leche and Chocolate Mousse Jars

1. Preheat the oven
   Set your oven to 375 °F (190 °C) and prepare a baking dish by lining it with parchment paper. This ensures easy removal of your chocolate cake later and a perfectly baked base.

2. Prepare the Chocolate Cake:
   Melt the butter and chocolate together in a saucepan. In a separate bowl, mix the dry ingredients. Whisk the eggs with sugar and vanilla, then combine this with the cooled chocolate mixture. Gradually add the dry ingredients and sour cream, mixing until just combined, and then stir in hot water until smooth. Pour this batter into the lined dish and bake for 15-20 minutes or until a toothpick inserted into the center comes out clean. Allow it to cool completely before crumbling into pieces.

3. Make the Chocolate Mousse:
   In a saucepan, melt the butter and semi-sweet chocolate together. In another bowl, whisk egg yolks, sugar, and water until thickened. Combine this with the melted chocolate and chill it in the refrigerator until cool. Meanwhile, whip the heavy cream until soft peaks form. Reserve some for the topping, then fold the whipped cream gently into the chocolate mixture until smooth and creamy.

4. Assemble the Jars:
   In each mason jar, start by drizzling a layer of Dulce de Leche syrup. Next, add a layer of crumbled chocolate cake, followed by more syrup, and then the chocolate mousse. Repeat the layers, finishing the top with whipped cream, a sprinkle of crumbled cake, and a drizzle of Dulce de Leche to make them visually stunning. Refrigerate the assembled jars for at least two hours to let the flavors meld beautifully.

Optional: Garnish with chocolate shavings for an added touch of elegance.

Expert Tips for Dulce de Leche and Chocolate Mousse Jars

• Avoid Overmixing: Keep the chocolate cake light by mixing until just combined. Overmixing can lead to a denser cake that won t layer well in the jars.

• Chill Your Chocolate Mixture: Let your melted chocolate cool completely before folding it into the whipped cream for the mousse. This helps to keep the mousse fluffy and light.

• Layer Carefully: Ensure each layer is neat and evenly distributed in the jars. This not only enhances the presentation but also guarantees a perfect bite every time you dig in!

• Refrigerate Properly: After assembling your Dulce de Leche and Chocolate Mousse Jars, refrigerate for at least two hours. This step helps the flavors meld together beautifully for a more indulgent dessert experience.

• Egg Freshness Matters: Use fresh eggs for your mousse. They create a better texture and enhance the richness of the layers.

How to Store and Freeze Dulce de Leche and Chocolate Mousse Jars

• Fridge: Store the assembled jars in the refrigerator for up to 3 days. This allows the flavors to meld beautifully while keeping the dessert fresh and delicious.
• Freezer: If you want to make these indulgent treats ahead of time, the assembled jars can be frozen for up to 1 month. Just be mindful that the texture may change slightly upon thawing.
• Airtight Containers: When freezing, ensure the jars are airtight to prevent freezer burn and preserve that delightful chocolate mousse consistency.
• Reheating: For best results, enjoy them cold. However, if you prefer warmth, let them sit at room temperature for about 15 minutes before enjoying; avoid microwaving, as this can alter the textures.
