Best keto dessert ever!! I am in love with it! Thank you for sharing this recipe!
So glad yo enjoyed the custard Lou Ann. Its one of my favorites too.
Perfect. I made it almost exactly to the recipe except I did half n half in place of the almond milk. I really cannot tell that it was substitute sugar. This is simply, custard, and there is no need to feel like you are missing something if this is a favorite dessert.
Thank you so much for the feedback, Rama. So glad you like the custard.
I LOVE this recipe. I have missed custard so much but now that I have this recipe, I make it sometimes 2x a week. I wish now I could find a Keto rice pudding this easy. I set my custard in the oven for tonight’s snack. Can’t wait.
Hi Kate, here is a rice pudding recipe made of cauliflower rice if you want to try that out.
Good morning Matt,
Can I use canderell as a sweet substitute?
Hello Jennifer, I have to confess I’ve never used it. we tend to steer clear of aspartame and use only natural sweeteners.
Would this custard work as eclair filling?
Hi Cindy, yes, it would be ideal for eclairs.
I had to stop myself from eating the whole thing! I had to substitute allulose and stevia for the swerve and coconut milk for the almond milk and it ended up divine! Definitely will make again!
So glad you enjoyed the custard Tanya and thank you for letting us know that the other sweeteners work too.
Absolutely perfect. I was concerned that it would taste different from traditional custards with the addition of the almond milk. But not only was it sensational but the lowering of the calories was an added bonus. Will be definitely be making this again. Used erythritol (1/2 cup) as the sweetener.
Hi Rosemary, so glad that it worked for you. We have used erythritol with success as well. Thank you for your kind words.
I’m thinking a keto crust for a cheese cake and adding in sweet coconut to this recipe it would make a French coconut pie
Sounds tasty, let us know how it goes Laurel. We do have a keto custard tart recipe here if you’d like to try that, it is delicious.
Hi Michelle,
I think you might be looking at a different product or misreading the label as Natvia has 0g net carbs per 100g. Sugar alcohols are not included in carb counts as they have no impact on blood sugar, so just double check that you haven’t counted them by accident.
I made a custard pie (not your recipe) with only almond milk. The result was set custard on top of ¹/² in of water! Gross…. before I try your recipe have you ever had this issue? I am assuming using ¹/² almond and ¹/² heavy cream will gratify this? Thanks so much
Hi Julie,
I have noticed that almond milk has a tendency to split when cooked. We haven’t had anything like that happen with this recipe, only positive comments coming from people who have made it. I hope that addresses your concerns 🙂
Love this! I make it in individual servings so I have portion control otherwise I could eat the whole thing at once!
What a great idea, Janet! I’m so glad that you love it 🙂
Guilty! I ate the whole thing myself when I made this last week ♀️ But it was two separate days so I think it’s not so bad??? ♀️ It was just too yummy!
Mine is in the oven as I’m typing this! Used 2 oz Monk fruit granulated sweetener, vanilla almond milk (unsweetened) and vanilla extract. I tasted before I put in the oven and I’m soooo excited! Thank you for this recipe!!
I used Swerve granulated and 1% milk instead of almond milk. It was absolutely delicious. I thought it was just sweet enough and the nutmeg gave it an added bonus. Will definitely make this again! My non low carb family even liked it, but I’m not sharing next time.
So glad you like it Lacey it’s one of my favorites too.
I make this at least once weekly now and I love it even more using almond milk.
I’m so glad to hear it’s on your regular menu Lacey! Thank you for your kind words 🙂
First time making this, and it’s delicious. Better than shop brought.
You are too kind Sally! Thanks for stopping by 🙂
Delicious! I substituted Monkfruit sweetener and vanilla extract using recipe measurements.
Can you substitute Swerve (granular or powdered) in a 1:1 ratio for the NatVia? It’s not available in my area and the Amazon link shows only available from third party sellers.
Can you substitute vanilla extract for the vanilla essence in a 1:1 ratio?
Hi Kathi,
To answer your questions; yes and yes!
I used golden monkfruit 1:1 and a better grade of vanilla 1:1…was excellent!
Nice and silky! My non keto kids liked it but I’d add more sweetener and vanilla next time
I forgot to rate
Beautiful desert; very simple yet delicious. Note, I used a shallower dish so it took 15 minutes less time; I would have preferred more depth but didn’t have a deeper dish.
