Low Carb & Sugar Free Diplomat Cream Puffs


Low Carb & Sugar Free Diplomat Cream Puffs. 2g carbs each.

Sounds ever so posh, doesn’t it? Too good to be true? I totally understand your scepticism. I had to pinch myself after I made them and tasted them. They are impossibly good for words to describe.

Yep. You guessed it. This is my keto recreation of yet another classic of the high-end pastry world.

Let’s say you go to Italy or France. You enter a patisserie (or even a coffee bar if you’re in Italy) and you stare at tray after tray of amazing, fine-patisserie, dainty creations. You then try what appear to be elegant, mini eclairs filled with custard and topped with a bit of chocolate. One morsel. And you’re immediately taken to food heaven. Not what you expected. At all. But a million times better.

Now I’ve got you salivating, the bad news: if you’re after a throw-into-a-bowl-then-mix-and-bake recipe, you may as well move on to another web page. My Low Carb & Sugar Free Diplomat Cream Puffs require zero baking skills, as long as you follow each step with military precision. But it does mean preparing 3 separate elements plus drying and cooling time. So if you want something on-the-fly and dirt-simple, I’m afraid this isn’t it.Low Carb & Sugar Free Diplomat Cream Puffs

How to Make Low Carb & Sugar Free Diplomat Cream Puffs

They are just like choux pastry, but without wheat poison flour. Thin, light, and hollow once baked (if they rise as they should). Again, you must follow each step in the recipe with precision, or you will be disappointed.

What Is Diplomat Cream?

Crème Diplomate (as it is called in France) is a vanilla-y and custard-y cream that you use to fill a cooked pastry shell. Light and delicate, it is created by combining its two more famous siblings: Creme Pâtissière and Chantilly Cream. So, put simply, it is a custard mixed with sweetened + flavoured whipped cream. Totally gorgeous.Low Carb & Sugar Free Diplomat Cream Puffs

 Chocolate Topping

The ganache I use as topping for the puffs is the easiest element. No precision required here. You can even change ingredients to suit your preference. Or you can simply drizzle some melted dark chocolate over the puffs. Whatever floats your boat. I love my 100% cocoa chocolate, but it’s way too bitter for me to enjoy on its own, so I do things to it to make it more palatable. You don’t have to, unless you want to.

Do You Really Need Metric Weighing Scales?

Yes!!!! You absolutely, 100%, most definitely do. I put a note in every recipe about accuracy and metric measures, yet I keep being asked how to convert to volume measures. I cannot say this enough: cups and spoons are NEVER accurate. Conversions may work when large quantities are being used and accuracy doesn’t matter. But when you involve small amounts of whatever it is, you simply CANNOT expect a workable metric to volume swap.

Just Google “what is 15 grams in spoons/cups“. Even the web juggernaut who has an answer for everything finds it impossible. It will give you suggestions and charts that are approximate. Why? Because a gram is always a gram, but a spoon or cup of something depends on what that something is, how coarse or chunky it is, how well you packed it into your spoon or cup, and whether you filled it exactly to the level or slightly heaped.

Delightful, dainty morsels of high-end patisserie now fully ketofied and perfect for special occasions.
For the choux pastry:
For the Diplomat cream:
For the chocolate drizzle:
Make the choux pastry:
  1. mix dry ingredients.
  2. bring water and butter slowly to a simmer and immediately remove from heat, tip in dry ingredients and stir vigorously until it becomes a smooth paste.
  3. return to the heat and keep mixing until the mixture comes away from the sides of the pan.
  4. transfer to a Pyrex or similar mixing bowl, and let it cool down.
  5. pre-heat oven to 190°C static.
  6. when the mixture is barely warm, add egg a little at a time and beat vigorously with a balloon whisk until you see trails and it forms a ribbon when dropped from a height (you may not need the whole egg - stop adding when the paste is piping consistency).
  7. spoon or pipe 6 equal mounds onto a lined baking tray (parchment paper works better than silicone on this occasion).
  8. bake for 10 minutes, then reduce the heat to 170°C static and bake for a further 20 minutes.
  9. split each puff in half lengthways and transfer to a wire rack to cool completely (or return to oven - turned off and with door open - for another 5 minutes to dry out a bit more).
To make the Diplomat cream:
  1. using a medium Pyrex or similar mixing bowl, whisk egg yolk with stevia powder and erythritol until pale and fluffy, then stir in gelatine powder.
  2. heat up 100g of cream with vanilla paste or seeds in a small, heavy base saucepan, until just before simmering point (when tiny bubbles start to form around the edge).
  3. slowly pour the hot cream over the egg yolk mix, whisking vigorously.
  4. transfer the mixture back into the saucepan you used for the cream, place it over medium heat and whisk until it thickens, at which point, remove it immediately from heat - it is imperative that you don't let the mixture reach simmering point, or the egg will separate and you'll have a curdled mess in your hands, instead of a lovely smooth custard.
  5. transfer the thickened custard (Crème Pâtissière) back to the mixing bowl and leave it to cool down, then put it to the coldest part of your fridge to set.
  6. refrigerate another mixing bowl, and use it to whip 50g of cream with icing sugar and vanilla extract until soft peaks forms.
  7. now combine the whipped cream (Chantilly) with the set Crème Pâtissière and your Crème Diplomate is ready.
Fill the puffs:
  1. reserve 1 TBSP of the Diplomat cream and spoon the rest over 6 puff halves.
  2. place the remaining halves on top.
Add the chocolate drizzle:
  1. chop the chocolate square and mix it with the reserved Diplomat cream, icing 'sugar' and coconut oil.
  2. warm up the mixture over a bain-marie or in the microwave, until liquid enough to be piped or drizzled.
  3. use the chocolate to decorate your puffs as you wish, then refrigerate them for 1-2 hours before serving.
Keep refrigerated for up to 3 days. No need to cover.

Metric kitchen scales are an inexpensive yet invaluable gadget to ensure accurate measurement of ingredients. Store them upright in a cupboard or over your worktop and they'll only take up a tiny bit of space. Click HERE for the ones I use. For U.S. option click HERE.

    I wish you had given more specific instructions about the choux pastry…i am having trouble getting it the right consistency.

  2. Hello,

    Is there any substitute for the arrowroot starch and lupin powder?

    Let me know,


    • No, they only work with those ingredients. I’ve tried other recipes for eclaire-type pastry that used different flours, but none of them worked for me, in the sense that they were not light and puffy enough. Sorry for the late reply – I’m actually on safari in South Africa with only sporadic access to internet.

Make me happy! Leave a comment!
