There’s a crowd that absolutely loves their soy products, with soy nut butter being one of their go-to spreads as a replacement to nut butters. However, it definitely makes a case for itself, and it might be worth checking it out even if you haven’t been into soy products…
Now, that being said, we’ll directly compare it to an awesome nut butter: cashew butter. This nutty spread has a thick and creamy texture that is absolutely amazing, and is a great representative to several of the best characteristics that nut butters have to offer.
We’ll take a close look at each of these spreads, looking at their culinary uses, dietary versatility, flavor profiles, and more, all while setting them against one another so they compete for your attention!
So, let’s take a look and see: is soy nut butter or cashew nut butter better?

Let’s jump in!
Comparing soy nut butter vs cashew butter
Soy nut butter isn’t made from nuts, but has soy as an allergen. Cashew butter is made from nuts, giving it tree nuts as an allergen! Both spreads share a thick and creamy texture, although cashew butter tends to be a little thicker. They also share the versatility of being suitable for vegan diets, while cashew butter is also good for paleo diets (as long as it’s unsweetened). Neither spread will fit your keto diet, unfortunately.
We don’t have a concrete glycemic index for soy nut butter, but it’s likely low. Cashew butter has a known low glycemic index, which makes either of these a good choice if you don’t want your blood sugar levels spiking – talk to your physician first if you have any concerns with that!
| Soy nut butter | Cashew butter | |
| Taste | Somewhat stale, slightly sweet | Mild, nutty, sweet |
| Texture | Thick, creamy | Thick, creamy |
| Allergens | Soy | Tree nuts |
| Vegan? | Yes | Yes |
| Paleo? | No | Yes (if unsweetened) |
| Keto? | No | No |
| Glycemic index (GI) | Unknown; likely low | 1 oz cashews= 25 |
What is soy nut butter?
Soy nut butter is a thick and creamy spread made by grinding either roasted or unroasted soybeans down. It also includes soybean oil in the mix, making it a completely nut-free spread!
Roasting the soybeans brings out some extra flavor, but some brands will add palm oil and sugar to further enhance the taste, so check the label if you don’t want those things.
What is cashew butter?
Cashew butter is also a thick and creamy spread, and is made by grinding roasted or raw cashew nuts into a smooth paste. You can easily make cashew butter at home, as the only other ingredients are salt and oils (like coconut oil) to enhance the taste and texture.
Cashew butter can fit a paleo diet as long as it’s unsweetened, and some brands add extra sugar – so it’s important to look at the label before you buy it!

The biggest difference between soy nut butter and cashew butter is their flavor.
Soy nut butter boasts a unique stale and slightly sweet flavor, while cashew butter has mildly nutty and slightly sweet taste to it.
Their textures are both thick and creamy, with cashew butter usually being a little thicker. Otherwise, they’re quite similar in this regard!
They do have nutritional differences, which we’ll take a look at in just a bit!
