How to Make Maple Cream (The Science of Sugar Crystallization)

If there’s anything more maply than maple syrup, it’s maple cream. It’s not as common as maple syrup and you won’t find it in most supermarkets. Which is a shame, because if anything, it tastes even more like maple than the regular syrup.

Maple cream actually is a great feat of sugar crystallization science. Cooking the syrup just a bit more than the regular maple syrup creates this special consistency.

What is maple cream?

Maple cream is a thicker version of maple syrup. As you can see on the photo below it doesn’t pour smoothly, instead, you’ll get blobs of it falling from your spoon. That said, maple cream is made from maple syrup and nothing else. The reason it behaves so differently is because of how it has been made.

Regular maple syrup is completely liquid. It contains a lot of sugar, but all of it is dissolved in the liquid. When you make maple syrup, you boil it down such that it concentrates enough to not spoil easily (high sugar content lowers water activity), but not so thick that the sugar in the syrup crystallizes. However, maple cream is cooked just a little more, causing the sugar to crystallize and thicken up.

Crystallization of maple syrup

So why & how does maple syrup crystallize into maple cream? This all has to do with the science of sugar crystallization.

Apart from moisture and several other ingredients, maple syrup is made up of a mixture of sugars (carbohydrates): sucrose, fructose & glucose. Sucrose is the same as the regular sugar you’d buy in the supermarket. One molecule of sucrose is made up of one molecule of glucose and one of fructose.

Most of the sugars, 88-99%, in maple syrup are sucrose molecules, with the remainder being fructose & glucose. That composition can change during the harvest season though as we discussed when exploring how maple syrup is made. Early in the season the sucrose content tends to be higher than later in the season. And lighter maple syrup tends to contain more sucrose than darker maple syrup (although it is not a perfect correlation).

The magic of sucrose crystallization

The (crystallization) science of sucrose is quite special and is the basis for making maple cream. There are a few things you need to know for understanding maple cream:

  • At higher temperatures, more sucrose can dissolve in water. That is, you can dissolve more sugar in your hot tea, than in a cold cup of tea.
  • The higher the concentration of sugar in your sugar syrup, the higher its boiling point. Regular water boils at 100C (212F), sugar syrups have boiling points up to 154C (309F)! For example, a syrup with about 90% sugar boils at about 120C (248F).

When you boil a sugar syrup to such high concentrations and temperatures though, it will not be stable when it cools down. There will be more sugar in there than can technically be dissolved in water at that temperature. What happens next depends on how you treat this so called ‘supersaturated’ solution and can be explained with a state diagram (which is very similar to a phase diagram).

Why maple cream crystallizes

So let’s walk through the state diagram and see what happens:

  • Maple syrup itself already has a boiling point slightly above 100C (as we discussed when discussing maple syrup in more detail) because of the higher sugar content, but it is low enough to all stay dissolved at room temperature.
  • When you bring maple syrup to the boil (red arrow pointing upwards in the graph below) and measure the temperature, it will be slightly above 100C.
  • To make maple cream you then continue to boil the syrup (red arrow pointing right). By doing so you evaporate water and increase the concentration of sucrose. You have to boil it to 112-114C (233-237F).
  • If you then cool the mixture down (red arrow pointing downwards) you end up with some sucrose molecules crystallizing and some remaining in solution aka maple cream consistency!
  • The higher the temperature you boil to, the higher the concentration of crystals. Getting to the right temperature is thus important to get the right amount of crystals.

Rough sketch of a sucrose state diagram (based on Schmidt, 2012). The red arrows represents what happens when making a maple cream. The x-axis represents the sucrose concentration in a water/sucrose mixture. The y-axis is the temperature of the mixture. Underneath the orange (boiling point) and left of the blue (solubility) line the sucrose dissolves fully in water. Right of the blue (solubility) and left of the grey (glass) lines, there is too much sucrose in the water and part of it will crystallize.
Maple syrup is more complex than just water + sucrose. As a result, the exact location of the curves will change, but the basic science behind it remains the same.

Controlling maple cream crystallization

So that’s the theory! In reality, maple cream production is a bit more complicated. Since maple syrup doesn’t contain just sucrose and water, but also other sugars, as well as impurities that affect sugar crystallization the system isn’t as ideal.

Fructose and glucose in the maple syrup can inhibit crystallization of the sugar crystals. As a result, you might need to concentrate the syrup even more, to induce the crystallization. That is, you need to boil it to a higher temperature. That higher temperature does increase the risk of the syrup burning or creating other off flavours.

Since maple syrup is a natural product, its composition can vary quite a bit throughout the season, between farms and between batches. This makes making maple cream more challenging, since every maple syrup might require slightly different temperatures to crystallize properly.

Controlling crystal sizes – stirring

After you’ve boiled the maple syrup and leave it to cool down to form maple cream, you’ve still got a job to do: stirring. Leaving the maple cream to cool down will cause crystallization to occur. However, the crystals might form in some places and not as much in others. As a result, you can end up with few large crystals, instead of a lot of very small ones.

This is why you want to stir the maple cream while it’s cooling down or when it has just cooled down. The stirring will break up larger crystals and induce crystal formation of new ones (because of the friction). The mechanism is actually quite similar to the churning of ice cream during which you form small ice crystals.

Adding crystals

If you’re making maple cream at home there is another trick to help induce crystallization: add sugar crystals. You can add powdered sugar (icing sugar) to the maple cream. The small, fine sizes of the sugar will form a starting point for crystals to form on. Note, if you’re making ‘pure maple cream’ this is not allowed since icing sugar is made from beet or cane sugar.

Maple cream is made with just maple syrup, nothing else! Maple cream is a concentrated and crystallized version of maple syrup.

To make a good maple cream you will need a thermometer and you'll make your life a lot easier if you also use a stand mixer, there is a lot of mixing involved!


  • Maple syrup (you will get about the same amount of cream as the amount of maple syrup you start of with, you only evaporate a little moisture).


  1. Bring the maple syrup to the boil in a pot and continue to boil on a medium heat.
  2. Continue to boil until the syrup has reached 112C (235F).
  3. Pour the thick syrup into the pot you'll be using to stir in for the next few steps. Make sure it can handle the heat! If you're using a stand mixer, use your metal bowl.
  4. Cool the syrup down in the fridge (faster cooling will prevent any preliminary crystallization) until just above room temperature (the exact temperature is not as important here).
  5. Once its cooled down, start stirring. If you're using a stand mixer, use the paddle blade at a low/moderate speed. Once it starts thickening up you may want to keep an eye on it to ensure the mixer doesn't get stuck. This stirring can easily last up to 30 minutes. Alternatively, you can stir for 10-15 minutes, walk away and come back about an hour later, it may have crystallized in the mean time!**


*You can use maple syrup to which a fruit syrup has been added (we used raspberry flavour maple syrup). However, that does increase the amount of fructose and glucose so you might need to boil it to a slightly higher temperature!

**If your maple syrup doesn't crystallize at all, despite vigorous stirring and waiting, you may need to boil it to a slightly higher temperature. Simply pour the syrup back into the pot and reheat again, this time to a few degrees (2-3C)  higher than the previous time and start over. If the opposite happens: you've got too many crystals and it has become too thick, add water, transfer back to the pot and re-heat, this time cooking to a few degrees lower temperature.

  1. This is fascinating. I wonder, however, about the addition of powdered sugar as all the powdered sugars I know contain cornstarch. Through cornstarch is a carbohydrate, now I think of it…

    • Hi Maggy,

      Great thought, didn’t even think of it! That said, there is only very little corn starch in powdered sugar, just to prevent it from clumping. The small amount shall not affect your maple cream in this scenario.

  2. Hello Dear
    Can i get on sugar from fruit syrup like from maple.
    Or ther are some modifications?
    With best regards

    • Hi Ameer,

      Yes, maple syrup contains sucrose (‘regular’ sugar), but also a few other types of sugars. What that answer your question?
