I have a serious love for chocolate and this chocolate mousse tart does not disappoint. I used a dark chocolate with 72% cacao, nice and dark but not too bitter. I can almost garuntee that if you make this no-bake chocolate mousse tart for your sweetheart, you will score major love points. You're very welcome.I'll be going out for dinner this year, but on the 13th, the day before Valentine's Day and we had to make the reservation weeks ago. It gets way too crazy on the 14th, sometimes the best idea for date night is when you cook at home. Make this tart the day before and all you have to do is let it come to room temperature as you tuck into your main course. It couldn't really get easier, did I mention it was no-bake?

This chocolate mousse tart is rich and you can tell by the ingredient list. Chocolate, mascarpone cheese, heavy cream, and egg yolks. Because it's no-bake you might be wondering about the egg yolks? No need to worry because if you use Safest Choice Eggs, you'll be set. Davidson's Safest Choice Eggs are pasteurized making them safe to use in amazing recipes like this.The eggs are dipped in an all natural water bath, hours from being laid and heated to exactly the right temperature to kill possible bacteria and avoid any risk of salmonella. This is good news for me because I love my eggs with a really runny yolk. Happy Valentine's Day!
