Raspberry chia pudding is the recipe we make most often when a dessert needs to be ready before anyone asks for one. You stir four weighed ingredients together, leave the jars in the fridge overnight, and the chia does the thickening on its own. Because the berries, cream and seeds are all weighed, the carbohydrate count on the card is a real measurement rather than a guess pulled from a similar recipe elsewhere.
Key Takeaways
- Everything that carries carbohydrate here is weighed and counted
- Chia needs a stir after five minutes, then four hours of chilling
- Raspberries contribute more carbohydrate than the cream does
- Erythritol is a sugar alcohol and is not counted as a net carb
- Jars keep four days, so it is a genuine make-ahead dessert
1. Why Chia Thickens Without Cooking
Chia seeds absorb roughly nine to ten times their weight in liquid. The soluble fibre around each seed forms a gel, which is why a spoonful of seeds turns a cup of cream into something that holds its shape on a spoon. No heat and no starch are involved, so nothing in the recipe has to be thickened with a flour substitute.
That same fibre is why the seed looks high in carbohydrate on a per-100g basis but contributes far less net carbohydrate. Our weighed record for chia lists 42.1 g of total carbohydrate and 34.4 g of fibre per 100 g, which is 7.7 g net — and the recipe only uses 60 g of seed for four servings.
- 60 g of chia carries about 4.6 g of net carbohydrate across the whole batch
- Stir once after five minutes to break up clumps before the gel sets
- A wider jar sets faster than a deep, narrow one
2. Where the Carbohydrate Actually Sits
People usually assume the cream is the problem in a dessert like this. It is not. Heavy cream at 36% milkfat carries about 2.8 g of carbohydrate per 100 g, almost all of it lactose, so 330 g of cream contributes roughly 9.2 g to the batch.
The raspberries contribute more per gram than the cream does, and the chia contributes more again. That is worth knowing if you want to adjust the recipe: cutting the berries in half removes about 3.4 g from the batch, while cutting the cream simply makes a thinner pudding for very little carb saving.
| Ingredient | Weighed amount | Net carbs in the batch |
|---|---|---|
| Chia seeds | 60 g | 4.6 g |
| Heavy cream | 330 g | 9.2 g |
| Raspberries | 125 g | 6.8 g |
| Vanilla extract | 5 g | 0.6 g |
| Erythritol | 25 g | not counted |
3. The Details That Decide the Texture
Warm the cream only enough to dissolve the sweetener. If it simmers, the fat can split and the pudding turns grainy, and no amount of whisking brings it back. Take the pan off the heat before the chia goes in.
Powdered erythritol dissolves far more readily than the granulated version, which tends to stay gritty in a cold, fat-based mixture. Allulose behaves similarly and browns faster if you ever warm it, so keep the heat low either way.
Crushing two-thirds of the raspberries into the pudding spreads the fruit flavour through every spoonful and leaves the rest whole for texture on top. Frozen berries work without thawing, but check the bag for added sugar before you tip them in.

Sealed jars keep four days in the fridge. The pudding thickens further on day two, so loosen it with a splash of cream if that is too firm for you. Stir before eating, since the berries release juice as they sit.
It does not freeze well. The gel structure breaks down on thawing and the pudding turns watery, which is a rare case where freezing genuinely ruins a low-carb dessert.
- Four days in a sealed jar in the fridge
- Stir before serving — juice from the berries settles
- Do not freeze; the gel breaks and weeps on thawing
5. How This Card Was Counted
Each weighed line is matched to a per-100g record from USDA FoodData Central, scaled by the gram weight in the ingredient list, and totalled. Net carbohydrate is total carbohydrate minus fibre. The batch total is then divided by four jars.
Anything we cannot weigh or match to a record is named on the card as not counted rather than estimated. Here that is the erythritol, which is a sugar alcohol with a negligible effect on blood glucose, and the pinch of salt, which weighs too little to register on any scale a home cook owns.
Frequently Asked Questions
Yes, and it makes the recipe dairy-free. Full-fat canned coconut milk is not in our weighed source set, so the card cannot count it — use the figure printed on your carton and add it yourself, or run the batch through the recipe calculator. Avoid the drinking-style cartons, which are mostly water.
Four hours is the minimum, and overnight is better. Chia absorbs liquid slowly at fridge temperature, so a pudding stirred at lunchtime is usually ready by dinner but noticeably better the next morning.
Because most of the carbohydrate in chia is fibre, which is subtracted to give net carbs, and because the seeds are spread across four servings. The batch total is about 21 g net carbohydrates, which divides into roughly 5.3 g per jar.
Yes. The pudding sets the same way without it. Erythritol is not counted in the carb figure either way, so removing it does not change the number on the card, only the taste.
Only with substitutions. Swap the cream for full-fat coconut milk, which you will have to count from its own label. Honey and maple syrup do not belong in a keto version, so keep a powdered sugar alcohol or a monk fruit blend as the sweetener.
