Coconut Tartlets with Orange Mascarpone Filling (Gluten Free)

Sunday, March 24, 2013

This dessert was the result of a few left over tidbits. I had some mascarpone from some ambitious plans for a dessert from earlier which never materialized. The fruit basket had two lone oranges whose skins began to slightly shrivel. And I was short on wheat flour, but I still had a fair amount of coconut flour from earlier experiments that had to be used up.


From that earlier experiment, which resulted in delicious gluten-free cupcakes, I knew coconut flour can be tricky. And for me, gluten-free baking has been a journey during which stumbling through trial and error seems to be the norm. Having done a quick search on coconut flour shortcrust pastry, I found nothing suitable. And so I decided to give it a try anyway, having accepted the fact that if it didn't work, at least it would be an experiment on which I could build on later (and it would still be a good excuse to use up the flour). And since it was snowing that particular day - the early spring warmth has since changed into a cold, at times snowy spell - I resolved to only work with the ingredients I had without having to make a run to the store. I had just enough butter for two tries.


Gluten-free baking calls for not only different ingredients but, I've found, also for different methods of preparation. For example, there is no need to wait for gluten to "relax" or "rest" - and since it's generally so tired it may be good to give it a rest altogether.

I usually roll out shortcrust pastry (for regular shortcrust pastry recipe, you can see a recipe I made here). Although the coconut flour dough can be made quite pliable, it is still brittle. So rather than rolling it out, the best way to handle it is to mold it into an elongated sausage shape, slice off a piece and mold it into the shell form directly. The dough firms up while baking and the texture becomes similar to that of a regular shortcrust pastry.


Coconut flour is generally much more absorbent, or thirstier, than wheat-based flour - and as a result requires much more liquid. Here I used as much water as I would add to about double of wheat based flour amount. I've also added xanthan gum to the coconut flour to give the dough the elasticity which is normally attributed to gluten. It comes as a powder, and becomes activated (and sticky) when it comes in contact with liquid. I learned the trick from my sister-in-law who bakes some amazing gluten-free desserts.


The filling I used for these tartlets is rich in orange flavor - which seemed appropriate for the snowy day. With just four ingredients, and when tartlets are chilled, the filling tastes like creamy orange-flavored ice cream, which goes well with the coconut flavored shells.


Coconut Tartlets with Orange Mascarpone Filling (Gluten Free)
Makes 12 1 1/2 inch tartlets

Coconut Flour Shortcrust Pastry

You will need:
1/2 cup coconut flour
2 tsp sugar
1/8 tsp salt
1 tsp xanthan gum
4 tbsp cold butter, cut into 1/4 inch pieces
1 tbsp sour cream
4-6 tbsp ice cold water

1. Preheat oven to 375ºF. Butter 12 1 1/2 inch-wide tartlet or brioche forms.
2. Whisk together flour, sugar, salt and xanthan gum in a bowl. Add the butter, and working quickly with your fingers, rub the butter into the flour mixture, until the mixture is flaky and there are no large butter pieces remaining. Mix in the sour cream. Gradually add the water, one tablespoon at a time, until dough starts to form and the mixture becomes soft and pliable. If it crumbles, continue to gradually add water up to 6 tbsp. Give the dough a knead or two and roll into a ball. Form the dough into a sausage shape about 2 inches in diameter. Place the dough on wax paper and slice into twelve even pieces.
3. With your fingers, take each piece and mold it into a tartlet form - the shell should be about 1/4 to 1/8 inch thick. Remove any excess and repeat with the remaining forms. Place the forms on a thin baking sheet. Bake for 9 minutes, then prick the bottom of each shell with a fork to prevent them from rising. Return to the oven and bake 11 to 13 minutes more (20 to 22 minutes total), until the shells are golden and the edges are golden brown. Remove to a wire rack and let cool before adding the filling.

Orange Mascarpone Cream Filling

You will need:
8 oz mascarpone cheese
3/4 cup confectioner's sugar
2 tsp orange zest (about 1 small orange)
2 tsp Triple Sec liqueur
Small orange slices, for garnish (optional)

Place the mascarpone and sugar into a bowl. Mix with an electric mixer until blended, scraping the sides with a wooden spoon, about 1 minute. Add the zest and the liqueur and beat 1-2 minutes more, until combined and the filling is thick. Do not overbeat. Pipe or spread onto cooled tartlet shells. Top with orange slices. Keep refrigerated until ready to serve.


  1. Oh MAAAAAN does that look delectable...!

    I feel like I'm always writing variations on the same comment on your beautiful blog, but that's because I always feel the same way when I visit: in awe of your recipes and gorgeous photos; inspired to cook up whatever fantastic recipe you've shared with us next; inexplicably hungry where before I was full; engaged by your eloquent writing; and wondering WHEN OH WHEN you'll get offered a book deal.


    But I suppose it's a good thing that you're consistently stirring all these thoughts in me on a regular basis, amirite? :-)

  2. You always take such gorgeous pictures Kat! I like gf doughs. When they taste good I don´t see the need to always eat wheat. And I have an unopened packet of xanthan gum too. Love these little tarts!

  3. Just lovely & a perfect way to welcome Spring! Beautifully done, Kat!

  4. Those are the most adorable little tartlets! Making gluten-free shrotcrust is no small achievement... I've tried it myself and failed many times over. Yours look so perfect! Love the flavor combo, too - coconut and orange sounds lovely on a chilly spring day.

    Also, my apologies for not keeping up lately - I'm having so much fun going back and reading through your posts! :)

  5. These look utterly delightful.

  6. We adore coconut! This is definitely a keeper, Kat. Bet it would be delicious filled with some tropical fruit curd too.

  7. I was wondering if you had any sugar-free dessert recipes?
