Chocolate Custard Tart

This is a decadent gluten free, grain free and optionally dairy free tart perfect for allergy friendly indulgence. It’s a bit of a project the first time as you get your head around everything but it’s actually really easy and I adore the custard making ritual if I have time to do it properly and not in the thermomix (Shhh, I don’t want to hurt the thermomix’s feelings)

Each first Sunday of the month, my family has a get together lunch, to make sure we all catch up at least every month. Most often times it’s more than that, for a cup o’ tea or a weekend glass of red, but to have a big feast together each month is always a real treat. This is delicious and if you’ve made my lemon custard tart and enjoyed that vibe, you shall love this. So many nutrient dense ingredients in here that it is truly a case of nourishment meets indulgence. A nice little slice shall satisfy for sure. Especially if you serve with berries and ice cream, am I right?

Enjoy your treat. Real food. Happy Bodies.

Chocolate Custard Tart Recipe


For the Custard Filling

For the Pastry

Equipment for Pastry

  • 1 Tart tin – quiche tin of some sort so you can ‘pop it out’ later.


For the Pastry

  • Pop all your flours, coconut sugar and cacao in your food processor or thermomix and pulse to combine and aerate (3 secs, speed 5 for TM users and about 5 seconds for Food Processor)
  • Add your chilled ‘fats’ of choice
  • Pulse until butter has disappeared into the flours (3 seconds on speed 6 for TM users / about 5 secs in a food processor)
  • Whisk your egg, vanilla and syrup (if using syrup instead of coconut sugar) together in a bowl
  • Add about 2/3 of this mixture slowly over 3-4 seconds into the processor. Has it gone to clumps? You’re done. Has it not? Add the rest.
  • Spatula out onto unbleached parchment paper and shape into a ball and pop in fridge for 20 minutes to make it more workable, as at this stage, it will be a little wet.
  • Preheat oven to 180C / 350F fan forced OR 200C / 400F non fan forced oven
  • Now, line your quiche / tart tin with coconut oil or butter and then dust with buckwheat flour / sorghum flour and shake off excess. This will help you when it comes to dislodging the tart later on!
  • Plop your pastry blob onto a layer of parchment paper and another piece of parchment on top – both a little longer than the tin’s length. TIP: If you used the syrup, dust the parchment and top of pastry ball with a little flour.
  • Roll the pastry into the shape you need for the tin you’ve chosen.
  • Peel top layer of parchment off
  • Flip parchment over on top of the tin and ease the pastry into the tin, pressing well into all the corners. Do not panic if your pastry cracks. Just top with a little blob of pastry from your excess and ‘plug’ the hole.
  • Any excess pastry? Make a couple of short bread cookies out of it.
  • Now, place parchment on top and weight it down with raw beans, rice grains or pastry weights and blind bake in the oven for 10 minutes with the weights in, and a further 15-20 minutes without – this will mean your base isn’t soggy for the finished product later – no one likes a soggy bottom!
  • Once the pastry is a nice deep brown without being black, it’s ready. Set aside.

For the Chocolate Custard

  • If you have a thermomix, place all the ingredients except the gelatin powder and chocolate into the TM and set timer to 7 minutes, 80 degrees. Then blend in the gelatin at the end, 5 seconds speed 6. Then blend the chocolate in, speed 7, 20 seconds. You’re done.
  • If you don’t, here’s the wonderful and easy, traditional way of making custard.
  • Mix your sweetness of choice and tapioca flour with your eggs.
  • Separately, heat coconut cream, water and vanilla on the stove in a saucepan until just a bubble or two are sighted.
  • Pour the coconut mixture very, very slowly into the egg and syrup bowl, continually stirring. If you pour too fast, you will cook the eggs into chunks and we don’t want that.
  • Then, pour everything back into the saucepan, low-med heat and stir continually until custard thickens. Once thickened, add the gelatin with a whisk, whisking for a few good seconds until incorporated. Then, break the block of dark chocolate into the saucepan and whisk around until it is fully melted and your custard is rich and chocolaty.
  • As the great Maggie Beer has a rule about pastry: Cold filling into cold pastry shell. Hot into hot shell. So, if you made your tart shell a while ago and it’s cool, cool your custard a little too before filling the shell.
  • Pour your custard into the tart shell. If you have some left, just fill a couple of ramekins for a delicious little back up dessert for another day.
  • Let it set in the fridge and when it comes to dislodging, do it carefully and steadily, only when the tart is fully set. I never take mine off the base, either, I just lift it out of the tin and leave the base under it.
  • You can add a garnish of freshly shaved / grated dark chocolate as I’ve done here, or even toasted coconut would be gorgeous.
  • Then slice and serve with some ice cream of your choice or crème fraiche and whatever berries you could find.

  1. that looks too good. I think i’ll have to keep that in mind for a special occasion otherwise I would be in severe danger of consuming it all over a very short space of time.

  2. Hello Alexx, made this yesterday & it turned out fantastic! Thank you so much for sharing. I am a new Thermomix owner so was a bit worried to try this ,but thrilled how amazing the taste is,….AND the PASTRY! Wow. Had to think a bit as being new…especially when it’s not spelled out, such as, “.Add about 2/3 of this mixture slowly over 3-4 seconds into the processor.” What speed? And “If you have a thermomix, place all the ingredients except the gelatin powder and chocolate into the TM and set timer to 7 minutes, 80 degrees.” What speed? Sorry, but was so worried it may not turn out. In the end I just followed the basic custard recipe speed. It is amazing. Will try the lemon one now. Thank you. Cherry
