Low Carb Coconut Pastry Cream

By Kim Hardesty

This creamy Coconut Milk Pastry Cream is perfect for your low carb desserts or on its own.

Jump to Recipe Print Recipe
Coconut milk pastry cream is a great dairy-free and sugar-free dessert option.

I'm so excited to bring this low carb Coconut Milk Pastry Cream to you today because it's really wonderful. This is the perfect recipe for those who need to avoid grains and dairy or are living sugar-free.

If you haven't been using pastry cream then I feel sorry for you because you have seriously been missing out. No, I'm just kidding. But seriously, you have.

What is Pastry Cream?

Pastry cream is a custard made with milk, eggs, and sugar that is thickened with either flour, cornstarch (arrowroot), or a combination of the two. The process involves heating the milk, mixing the dry ingredients together with the eggs, tempering the eggs with some of the hot milk, combining the two mixtures together, then cooking it on the stove until it thickens.

Upon refrigeration, pastry cream becomes quite firm and can even be piped to decorate a dessert. Although not difficult to make, it does take some attention so that the eggs don't curdle. I think you'll be surprised how quickly you can make a batch of this low carb coconut milk pastry cream and then you'll want to use it on everything.

This low carb pastry cream recipe is made from coconut milk and almond milk. Coconut milk not only gives this pastry cream a distinctive flavor, but it is actually a heart healthy dairy alternative. And almond milk is mild, low in fat, and low in sugar so it is the perfect choice for those following a low carb or ketogenic lifestyle. The ingredients are wholesome and the procedure is the same our grandmother's used when making homemade pudding from scratch.

Pastry cream is not hard to make, but it does take some care. So, now that you know what it is and how to prepare it, you're probably wondering what this low carb coconut milk pastry cream can be used for...

Pastry cream is traditionally used as a filling for pastries: cream horns, cream puffs, Napoleons, eclairs, danish, and donuts come to mind.  But, pastry cream can also be used between layers of cake like Boston Cream Pie or as the base for fresh fruit tarts, banana cream pie and coconut cream pie.

And this coconut milk pastry cream is soooo good that I'm going to try  it in as many things as I can!

Give it a try. You won't be sorry.

Ingredients

  • 1 cup full-fat coconut milk
  • 1 cup almond milk (or more coconut milk or soy milk)
  • ½ cup low carb sugar
  • 1 tablespoon cornstarch or arrowroot
  • ¼ teaspoon xanthan gum
  • 1/16 teaspoon salt (just a pinch)
  • 1 large whole egg
  • 3 large egg yolks
  • 1 teaspoon vanilla extract
  • 2 tablespoons ghee (or butter) (omit if completely dairy-free)

Instructions

  • Pour the coconut and almond milk into a 2 quart sauce pan or pot and bring to a simmer over medium heat.
  • In the meantime, place all of the dry ingredients into a medium bowl and whisk to combine. Add the whole egg and yolks to the dry ingredients, whisking until smooth. Set bowl near the stove. When the milk mixture begins to simmer, stir it to evenly distribute the heat. Turn off the stove. Now, using a small ladle, slowly add the hot milk to the egg mixture whisking all the while, until half of the milk mixture has been incorporated. Now pour the rest of the milk mixture into the bowl. Whisk well and pour the ingredients back into the pot.
  • Turn the heat to medium-low and gently stir with a whisk as the mixture heats. As the mixture begins to thicken, turn the heat to low and begin whisking more quickly. Now is the time to minimize distractions because the magic will happen all at once, and voila, you will have a thick mixture resembling a loose pudding. Once thickened, it will begin to simmer very slowly. Continue to cook the custard for a full minute.
  • Remove the pastry cream from the heat and stir in the vanilla and ghee (if using). Place a piece of plastic film over the pastry cream, pushing it down onto the surface. Now poke holes through the plastic and let cool in the refrigerator before using.*Note: I like to cool my pastry cream right away by placing my bowl over ice and stirring until the mixture is cool. Then I cover with plastic film and refrigerate.
  • The pastry cream becomes quite thick as it cools.

    Thanks for this recipe! I made my husband a Boston cream pie with this as the filling. It was so delicious! We’re mostly dairy free(except for butter).
    I used 1 1/2 tablespoons tapioca starch for the thickener, and no xanthan gum, since my coconut milk seemed to have a lot of guar gum in it.

    Loved this pastry cream!

    My only issue was that it did not “set” enough. It did thicken up quite a bit, but was still a bit runny in my tart. So I need to either thicken it longer on the stove, or add a bit more Xantham gum or Arrow Root...

    Any suggestions?

      Hi Michael. I think it may have needed a little more cooking. You can add a little more xanthan gum, but don't add too much or the pastry cream will be slippery in texture. -Kim

    Love this pastry cream, I recently made it for my cupcakes filling. Just have a quick question, if I freeze the pastry for 1 week how do I defrost it and make it have a thick consistency?

    Thank you.

      I'm happy you like the recipe, Mari. I've frozen the pastry cream as part of a dessert like my low carb lasagna and then defrosted overnight in the refrigerator with no ill effects. Did you find it watery after freezing? -Kim

      I've never used tapioca starch before, Gurnoor Bhutta. I Googled it and it seems you would use LESS tapioca starch, like 1 1/2 tapioca starch to 1 tbsp cornstarch or arrowroot powder. -Kim

    Just want to state that Ghee is made from milk and those of us who are allergic to milk, which includes casein.. would beg to differ on the dairy free statement. it's hard to find good recipes that exclude dairy. Thanks for this one.. i can find a way to modify it.

    Reply
    • Kim

      June 30, 2018 at 11:42 am

      Denise, I am not allergic to milk but from the reading I have done (my daughter is on the Spectrum so we were gluten-free and casein free for a while) any lactose, casein, milk sugars or proteins should be almost completely filtered out leaving just the milk fat. When I make Ghee, I skim milk solids and foam from the top, then filter it as I add it to jars, leaving any solids behind in the pot. Many better ghee refiners use centrifugal technology to separate the butter fat from the other components of whole butter. As I've said, I don't have a milk allergy so I haven't tested the effects, but a good ghee should be fat and virtually free from other allergens. Please point me to other data you have so that I can read up on it. I know that research changes quickly and I would rather remain current. Thank you so much for you comment. I appreciate it. -Kim

    Can this be made without xanthan gum? I don't have any and am hoping the cornstarch is sufficient?

      June 01, 2018 at 6:45 pm

      Hi Monika. It should still thicken, but maybe not as much as a proper pastry cream, which uses a lot more flour or cornstarch (arrowroot). Make sure to cook it completely so that it thickens. It would also depend on what you are using the pastry cream for. -Kim

          It might. I found that relying on xanthan gum only, made for a slippery feeling pastry cream. Make sure to cook it well so that it thickens properly or it may be runny. Many people either undercook a pastry cream, resulting in a runny product or overcook it, scrambling the eggs. -Kim

    Do you think this could be made with gluccomann powder or xantham gum as the thickener instead of arrowroot or cornstarch?

    Reply
    • Kim

      March 29, 2018 at 3:48 pm

      Laura, I tested the recipe with both more xanthan gum and with glucomannan powder. Adding more xanthan gum makes the texture slippery and the glucomannan makes it gloppy. I found that using the starch made the texture very close to regular pastry cream (which commonly calls for 1/4 cup of starch or flour). You may use what you wish, to thicken the pastry cream, I just try to provide the best possible version. Thanks so much for your question. Have a wonderful week. -Kim

    Kim, your info regarding "HOW" to use the new Low Carb, Gluten Free ingredients to create delicious recipes that are equal to, or better than the ones we made from "scratch" with wheat, etc. In the past is highly appreciated. There are so many new things, like Coconut flour's absorbing so much liquid, that matter. Thank you so much for your research, dedication, and willingness to share with others. God says we all have a purpose in life. I'm thankful that your site & sharing your knowledge is one of yours. Blessings.

    Ghee is not dairy free,, what can be subed?

    • Kim

      July 11, 2017 at 1:25 pm

      I respectfully disagree, Melissa. Clarified ( or drawn) butter still retains milk solids. If ghee is made properly it's pure milk fat. It is cooked until the milk solids at the bottom of the pan turn nutty brown and the solids at the top are skimmed off. I filter mine through a coffee filter and it's virtually dairy free. My daughter is on the spectrum and we used homemade ghee for years. If you feel uncomfortable using it, leave it out. Enjoy the recipe and your week. -Kim

      February 18, 2017 at 2:52 pm

      Thanks Liselle. I think that if you are not low carb and are using a liquid sweetener like brown rice syrup, then adding more cornstarch (or arrowroot) would be the way to go. The liquid would thin the mixture and I have used the minimum amount of thickener to keep this recipe low in carbs for my users. I think 1-2 more teaspoons would work. Thanks for your kind comments. Enjoy the recipe. -Kim

      Hi, Tresa. I had to look-up Vita Fiber on Amazon. It sounds like a very similar product, not exactly the same, but probably similar enough that it could be used as a replacement. I have not used it so I am uncertain if it would work in something like the Homemade Caramel recipe I have on the site, but I am sure it would work in the Hot Fudge Sauce and other recipes calling for it as an ingredient. Does Vitafiber come in a brown/molasses flavored syrup? I did not see anything like it on Amazon. Have a nice day! -Kim

      Hi, Leslie. Thank you! Sugar is sweeter, so 1/2 cup would yield a little sweeter product. My stuff is less sweet, so that would be a good place to start. :) If the pastry cream isn't thick enough for your application, you can always drip it in a coffee filter or paper towel or use a little more cornstarch next time. I used the absolute minimum to keep carbs down. -Kim
