Healthy Peanut Butter Mousse
Some of you may be asking "what's so unhealthy about peanut butter?" Well, nothing, really....except when you eat it by the capfuls!!!
But guess what, now you can! One cup of this healthy peanut butter mousse is not only low in carbs, sugar-free, gluten-free, vegan but also jam-packed with protein!

Ingredients make all the difference!
Since this recipe only calls for 4 basic ingredients, I highly suggest that you use the best brand of each of the ingredients, as their flavours and/or textures will make or break this recipe.
First, you will need some tofu. Tofu comes in silken, regular, firm, extra-firm and super-firm. Common thought would be to use silken tofu as it is already smooth, but I actually suggest that you use firm or extra-firm tofu instead. Part of the difference between the two types of tofu is how much water is pressed from the tofu. Silken tofu has a higher water content than firm tofu. Since the tofu is pureed until smooth, using firm tofu results in the same creaminess without the added water. The brand I just recently started using is a soy-free tofu by Big Mountain. It contains 0 grams of fat as well as 0 grams of carbs, which makes it a pure protein product and perfect for PSMF days!
Next, you will need some peanut butter. I personally LOVE Member's Mark Natural peanut butter, but any smooth (or crunchy!) peanut butter will work. I do not suggest the true "natural" style peanut butter that has the separation of oil, as it does not blend as well.
Lastly, you will need to add your protein sources. A combination of Quest Powdered Peanut Butter along with either Naked Nutrition Vanilla Collagen Creamer or The Fittest Butter Vanilla, adds not only tons of protein but also gives the best flavour for the most delicious vegan keto mousse.

Keto Peanut Butter Mousse - Not an exact recipe
You may find that to be a weird statement, but since I have made this high protein vegan peanut butter mousse several times, I always seem to change it ever so slightly. For this very reason, you will notice in the recipe card that I have given varying quantities when listing the ingredients.
THIS RECIPE IS FOOLPROOF, so do not feel like you have to follow it exactly!
High Protein Vegan Peanut Butter Mousse Tips
Since I have been a little vague in my recipe card, I will give you some tips and tricks to ensure that you have the most delicious (and healthy!) high-protein peanut butter mousse!
- Puree first - Make sure that you ONLY add the tofu to the bowl of a food processor and process it until it turns out really smooth. Do not add ANY ingredients until the tofu is nice and creamy. If your tofu does not want to turn into a silken version, you can add a little water or almond milk, one tablespoon at a time.

- Add the ingredients one at a time - Start by adding the peanut butter, the peanut butter protein powder and then the collagen. Make sure that you run the food processor and incorporate each ingredient before adding the next. Finally, taste the mixture and slowly add the sweetener. All protein powders and collagens have varying levels of sweetness, so you want to add as much or as little to suit your taste
- Add a little of this and a little of that! - Next, add a splash of vanilla and some salt. Taste the mixture again and tweak it to suit your fancy. If the mixture seems too dry, simply add a little almond milk. If the mixture is too wet, try adding more protein powder. Once the consistency and flavour are to your liking, feel free to incorporate "add-ins" such as chocolate chips, chopped up sugar-free white chocolate melting wafers, chopped up nuts, sugar-free jam or add some chopped up berries (only add these right before eating or they will make your mousse too watery!)
How long will this high protein peanut butter mousse last?
This keto peanut butter mousse will last at least 2 weeks in the fridge. I have not tried freezing it, so I do not know what happens when you thaw i,t but if you try it, let me know how it turns out!

Shouldn't I avoid tofu on a keto diet?
Soy tofu got a bad rap due to outdated concerns about phytoestrogens and hormone disruption, which have since been debunked by current research. Today, it's recognized as a nutrient-dense, plant-based protein that supports heart health and may reduce the risk of certain cancers.
As for keto, although there is not really any fat in tofu, there alse isn't really any carbs either!
My favourite tofu is by Big Mountain. Big Mountain is a tofu made from fava beans, so there isn't even any soy in the product. Plus, since 12 oz of tofu contains 64 grams of protein, 0 grams of carbs and 0 grams of fat, tofu is great for protein-sparing fasting days!

- Total Time: 5 minutes
- Yield: 4 servings 1x
Ingredients
- 12 oz extra-firm tofu
- ¼ cup smooth peanut butter
- 2-4 scoops peanut butter protein powder (casein, pea or a mix)*
- 1-2 scoops vanilla collagen protein powder
- ¼-½ cup sweetener
- 1 tsp vanilla
- salt
Instructions
- In the bowl of a food processor, add the tofu. Process until nice and creamy, about 3-5 minutes.

- Divide the mixture evenly between 4 glasses and place in the fridge to firm, if desired (or eat it right away, if you want!)
Notes
- You may need to adjust the recipe to suit your taste and textures. IF it is too firm, add 1 tablespoon of almond milk at a time. IF the mousse is too loose, add additional protein powder. If the mousse is not sweet enough, add additional sweetener.
- *Do NOT use pure whey protein powder as the mixture will most likely become very "gummy" and not "mousse" like.
