Gluten-Free Nut-Crusted Chocolate Mousse Tart: It's flour-free. I'm nut kidding!

GF-ChocTart_051_750x500

I cringe when I hear the word, tart. It screams high-maintenance fancy, and always involves some finicky pie-type dough and finding a perfectly sized and shaped pan to fit it just right.

I tend to avoid tarts when scrolling through recipes, but with the emergence and more prominent use of almond and other nut flours, it seemed valid to create something simple, useful, and NUTTY for the gluten-free baker world.

A nut-based crust provides an easy-to-handle, tender, protein-packed nest for your favorite fillings, whether they be fruit, custard, or mousse. I know I’m LONG overdue for a chocolate recipe, so why don’t we fill our rich, buttery pistachio crust with some chocolate almond mousse?

We have two recipes to accomplish here, but thankfully both are simple and the baking time is short. Let’s get mixing, shall we?

Preheat your oven to 350° F.

IMG_9743Start by pulsing 3/4 cup pistachios in your food processor, taking care not to over-process into a paste.

IMG_9746You’ll want to be able to see slightly larger pieces here and there; but overall, the blend should be the consistency of a coarse meal.

IMG_9764Combine the pistachio meal with:

IMG_9770Mix quickly with a pastry blender or fork until the mixture looks crumbly, but will still hold together if you squeeze a handful of it.

Line a rectangular 4¼” x 13¾” x 1” tart pan; four mini 4½” x ¾” tart pans, or a 9″ tart pan with the crust mixture, pressing it evenly up the sides to make a thick crust as pictured above.

Bake the crust for 15 to 20 minutes…

…or until the edges are golden brown. Cool the crust completely before filling it.

And now, to make the smooth, dense mousse to fill this beautiful golden shell!

IMG_9717Start by mixing 1/4 cup confectioners’ sugar with 1 teaspoon Instant ClearJel.

Whip the heavy cream to soft peaks, then add the sugar mixture. Continue beating until the cream forms stiff peaks.

IMG_9724Mix 3/4 cup confectioners’ sugar with 8 ounces cream cheese, 2 tablespoons softened butter, and 1/2 teaspoon almond extract.

Once they’re mixed thoroughly, set the bowl aside.

IMG_9713Melt 2/3 cup bittersweet chocolate in your microwave, or over a double boiler.

IMG_9731Add the melted chocolate to the cream cheese mixture, and beat well.

IMG_9735Fold the whipped cream mixture into the chocolate cream cheese mixture.

IMG_9739Make sure everything is smooth and evenly blended.

Finally, pipe the mousse filling into the baked, cooled shell.

Serve the tart garnished with toasted pistachios or almonds, if you’d like to dress it up a little. A dollop of whipped cream never hurt, either. ; )

Such decadence. No gluten. No flour. Tons of protein. And yes, most importantly for so many – IT’S CHOCOLATE!

    It looks wonderful.
    I have a question though regarding the recipe actually being GF. When I clicked on the link for the ‘Instant Clear Gel’ in the comments and questions portion someone asks if ‘Instant Clear Gel’ is Gluten Free. The question is dated 03/03/2014.
    The response is as follows:
    “This item is not gluten free, Julie. It is produced on equipment that is shared with one or more foods which contain gluten. Please contact our friendly Customer Support Team at 1-800-827-6836 if you have any more questions about this or other KAF products, and we’ll be happy to help! Jesse@KAF”
    Has something changed since March? Is there a substitute for the Clear Gel? Maybe powdered gelatin or pectin?
    Thank you for any information.

      Our Instant Clearjel is not GF at this time. You can go old-school and use regular ol’ gelatin to thicken the mousse. Bloom it in the cream first, about a teaspoon of gelatin will make a nice smooth mousse. ~ MJ

      In this case, I would really stick to the chocolate as you will need to add fat and sugar to the cocoa to produce a similar product. Jon@KAF

    I would love to make this for a dinner party that I attending this weekend but do not have Instant Clear Jel. Is it possible to not use this or would not using it compromise the quality of the tart. I appreciate your help.

    Please note that Instant ClearJel is manufactured on equipment shared with wheat (per label), so may not be gluten-free enough for people with Celiac Disease or a severe wheat allergy. Is that ingredient optional?

      Maybe you should read other’s comments before posting to see if your topic is already posted. It would probably save the staff some time because they don’t have to answer the same question over and over again

    Have you ever heard of Dr. Oetker’s “WhipIt”? I have used it to good advantage in mousses, whipped cream, and other blends that are similar.
    It takes me years to use up items like the container of gelatin, or the clear jell. My old CA apt. has no insulation so the outdoors shares temp equivalencies in my kitchen any time of year, in spite of efforts otherwise! ;) Chocolate blooms terribly, (so I keep it in a box behind my bed near the A/C unit there.), powdered ingredients get stuck and hard, mixes go stale very quickly, etc. Long term storage of any food items just is not feasible.
    I have tried to use and keep clear jell pie fillings , etc., here, but they just don’t work well. Those who ate it were not pleased (even commercial purchase of filling, so I don’t think it was the cook!)
    If I can use a couple of envelopes of WI, it would be perfect, and no long term storage.

    If you chance to shop at a Whole Foods, Cost Plus World Market, or other stores where Dr. Oetker items are found, you will find the small blue and white packets, name clearly printed on it. They come two packs together. I include this information in case you shop at one, or others might want to try them. Maybe you could carry it, although I do think you offer a whipping cream stabilizer too, do you not?

    I love this recipe! I have made similar crusts, and the combo of pistachios and almond is a nice blend. I have used the combo in your GF Dream Bars as well. Chocolate makes it a dream trinity with these nuts.

    Thanks for a grand recipe. I am going to an open house soon and want to make it for some GF guests who will be there.

    All the best,
