Chocolate Mousse Tart (& more Pâte Sablée)

This is my new favorite dessert to bring. Bring where? Anywhere! Potlucks, picnics, dinner at dad's, baby showers, and the like.

There's two sticks of butter in the crust. And one whole pint of heavy cream in the tart. So don't make this to keep at home and risk eating all the leftovers for breakfast. You'll thank me for this later.

I made this with Hershey's Special Dark chocolate. I usually go for the Ghirardelli or ScharffenBerger for fancy desserts, but the Hershey's was on sale and I wanted to try it out. I was a little iffy when I tasted the chocolate on its own, as it was too grainy and had that epitomous Hershey's flavor. But, once it was mixed with an ungodly amount of whipped cream and chilled into the sweet, cookie crust, the flavor was exceptional.

The recipe I based this on didn't really work out, so I had to improvise. At first, I made it worse, but it turned out great anyway. The recipe calls for chocolate and half the cream to be heated together in the microwave until the chocolate melted, then cooled to room temperature. Meanwhile, I whipped the remaining cream until stiff peaks formed.



Then, I was to fold the whipped cream into the melted chocolate/cream mixture. Even at room temp, the chocolate/cream mixture was too liquidy to fold the whipped cream into.



So I mixed it the best I could, then thought I could throw the whole mix back into the mixer to re-whip the cream. No, not happening. And then the whole mix was even more liquidy. I poured it into the crust anyway and threw the whole lot into the freezer. And lo and behold! It firmed right up and even had that velvety mousse-like texture I was going for. Whoo hoo!

The second time I made it, I melted the chocolate and cream using the double-boiler method instead of the microwave, let it cool, then folded the whipped cream in. Worked much better and was definitely a mousse and not a liquid.

double-boiler method is better

A note on chocolate mousse: Julia Child seems to have the go-to recipe, according to my limited on-line research. However, I was making the first tart for a very pregnant friend of mine and Julia's recipe (and most out there) feature raw eggs in the dessert. And raw eggs & pregnant women do not mix. So that is why I chose this simple recipe.

Also, I used the Pâte Sablée crust for this again and it was so good. So, so good. So good that I am going to include that recipe again since I have more pictures of it.

Pâte Sablée from Martha Stewart

2 sticks (16 tablespoons) unsalted butter, room temperature
3/4 cup confectioners' sugar
2 cups all-purpose flour
1 teaspoon salt

With a standing mixer on medium speed, beat butter and sugar until pale and fluffy, about 3 minutes. Reduce speed to medium-low. Add flour and salt, and beat until just combined and crumbly (do not overmix).


Shape dough into a 9-inch round disk, and wrap in plastic. Refrigerate at least 30 minutes (or up to 2 days), or freeze for up to 1 month.

For this recipe, you'll need to fully bake the crust before filling it. I bake it at 400* for about 25 minutes, then check for doneness. Doneness can be however dark you would like your crust to be. The first time I made this, it was pretty dark.


The crust browned nicely in the oven. This was the crust that was too crumbly for me to roll out; I picked up pieces of sandy dough and patted them into place in the tart pan.


You can see the rest of the dough on my cutting board in the top right of the photo. It was very crumbly.

The next time I made this, I chilled it just for a couple of hours instead of overnight. The crust rolled out nicely and baked up a little lighter.


This dough was still very soft. I couldn't pick it up all at once to place in the pie pan.


I used a bench scraper to lift pieces of the dough into the pie plate, then patched them together with my fingertips.


This crust was a little flakier.

Also, after I get the dough into the tart pan but before I bake it, I place it in the freezer for about 15 minutes. This helps firm it up a bit and prevents it from shrinking in the oven.

Now that you know how to make a perfect pâte sablée tart crust, let's move on to the chocolate mousse part.

Chocolate Mousse Tart adapted from Very Best Baking

1 recipe pâte sablée tart crust, baked and cooled
8 oz. dark chocolate, 62% cacao, chopped finely
2 cups heavy whipping cream, divided
2 T confectioner's sugar

To begin, set a saucepan with 2 inches of water over medium heat until it simmers. Reduce the heat to low. Place a stainless steel or glass bowl over the saucepan, making sure it doesn't touch the water.

Add chocolate and 1 cup of heavy cream to the bowl. Heat slowly, whisking as you go, until all the chocolate is melted and combined well with the cream.

When chocolate is thoroughly melted, remove from heat and set aside to cool. You want it to cool to room temperature, but still be melted.

Meanwhile, add the remaining cream and the confectioner's sugar to the bowl of a standing mixer. Whip the cream until it forms stiff peaks.



Add the whipped cream to the cooled chocolate mixture. Carefully, gently, fold the whipped cream into the chocolate.


It should look like this.

Scrape chocolate mousse into the prepared tart crust.



Place tart in the refrigerator for 4 hours or until firm.



Slice and serve. I serve this plain, but it would pair well with a fruit sauce or liqueur-flavored whipped cream.

Whole Lemon Tart and Pâte Sablée

aka Tarte au Citron for you francophiles. I got this idea from the fabulous Deb at Smitten Kitchen. If you haven't met Deb yet and have no idea what Smitten Kitchen is, go there now and visit. I think I have bookmarked more recipes from Deb than from any other site.

I first made this tart last year. At the time, I was using a tart crust recipe from my Better Homes & Gardens cookbook. It worked ok but was kind of blah. Then I tried the pâte sucrée (from Martha, of course), which is a richer dough made with egg yolks and a little sugar. This was better, but still not quite what I wanted.

I was interested in trying a pâte sablée (a sweet shortbread-like crust) with this lemon tart to counter the bitterness from the lemon peel. Most of the recipes call for ground almonds, which gives the crust that delicate, sandy texture. I don't like purchasing ingredients for one dish (or rather, a piece of one dish) so I put off trying it until last weekend. Mother's Day was coming up, and I was bringing dessert over to my Dad's for our family celebration. I was once again checking out recipes for pâte sablée online when I came upon Martha's recipe, which doesn't use any ground almonds! Why I hadn't seen this before is a mystery to me. Her recipe uses butter, confectioner's sugar, flour and salt. Perfect.

The best part about the pâte sablée recipe is that it comes together in the mixer. No cutting the cold butter into the flour necessary. That's always the hardest part for me. Instead, you use softened butter (2 sticks!) and cream it with the sugar, then add the flour and salt. Easy!

After chilling, the dough is still very soft, so I patted the dough into the tart pan instead of trying to roll it out. The recipe says it makes a 9-inch tart shell, but I had more dough than I needed. Of course if you like an extra thick crust, go for it! **On second thought, I think my tart pan is only 8 inches, so that may have been the issue.

In making tarts, I find it best to pre-bake the crust almost all the way before adding the filling. That way the crust is nice and brown and not gummy on the bottom. This is called blind baking. I learned a little trick from Deb: freeze the crust before baking it. That way the crust doesn't shrink down the sides of your tart pan. You can also line it with parchment and fill with dried beans or rice or pie weights, but I've found freezing works just as well, if not better. Then pop it into a 400° oven for 15-20 minutes. When it is a light golden brown, remove from oven and let cool all the way before adding the filling.

This tart recipe uses a whole lemon, as you may have guessed from the title. Except for any pesky seeds that might be hanging out. Just cut the lemon into small pieces and add it to the blender with the sugar and blend until smooth. Whisk in a whole egg, an egg yolk, corn starch and melted butter. This time I just blended everything in the blender and it worked fine. The color was a little cloudier but it still tasted great. The filling is intensly lemon with a good mix of tart, bitter and sweet. I've called it the grown-ups' lemon tart. With a pretty dusting of powdered sugar on top, it is a sure winner for brunch, picnic or family dinner.

Pâte Sablée from Martha Stewart

2 sticks (16 tablespoons) unsalted butter, room temperature
3/4 cup confectioners' sugar
2 cups all-purpose flour
1 teaspoon salt

With a standing mixer on medium speed, beat butter and sugar until pale and fluffy, about 3 minutes. Reduce speed to medium-low. Add flour and salt, and beat until just combined and crumbly (do not overmix). Shape dough into a 9-inch round disk, and wrap in plastic. Refrigerate at least 30 minutes (or up to 2 days), or freeze for up to 1 month.


Whole Lemon Tart from Smitten Kitchen

1 partially baked 9-inch (24-cm) sweet tart shell
1 average-sized lemon (about 4 1/2 ounces; 130 grams), rinsed and dried
1 1/2 cups (300 grams) sugar
1 large egg
1 large egg yolk
1 1/2 tablespoons (12 grams) cornstarch
1 stick (4 ounces; 115 grams) unsalted butter, melted and cooled

Center a rack in the oven and preheat the oven 325°F (165°C). Line a trimmed baking sheet with parchment paper and put the tart shell on the sheet.

Slice the lemon into thin wedges, remove the seeds, and toss the lemon and sugar into the container of a blender or food processor. Blend or process, scraping down the sides of the container as needed, until the lemon is thoroughly pureed and blended with the sugar, 1 to 2 minutes.

Turn the mixture into a bowl and, using a whisk, gently stir in the whole egg and the yolk, followed by the cornstarch and melted butter.

Pour the filling into the crust but be sure to leave 1/4 inch between the top of your filling and the top edge of your crust.

Slide the baking sheet into the oven and bake the tart for 20 minutes. Increase the oven temperature to 350°F (180°C) and bake for another 15 to 20 minutes, or until the filling is bubbling, lightly browned and set.  Don't overbake - tart will continue to set as it cools.

Transfer the tart, still on the baking sheet, to a cooling rack and allow it to cool for at least 20 minutes before removing it from the pan. The tart is ready to be served when it reaches room temperature.
