Soft, mousse-like chocolate protein bars with tahini, coconut milk, and plenty of rich cocoa flavorThese chocolate mousse protein bars combine cocoa, unsweetened chocolate, creamy tahini, and coconut milk for a soft, rich bar with plenty of plant-based protein. Unlike a typical dense or chewy protein bar, these have a softer, almost mousse-like texture that comes from using agar agar to set the mixture rather than baking it. With 1 teaspoon of agar, they’re soft enough to feel mousse-like but still firm enough to pick up and eat by hand. If you’d prefer a sturdier bar, you can simply increase the agar, although you’ll need to work a little faster when mixing and shaping because the mixture will begin to set more quickly. Protein is something I pay quite a bit of attention to as a 40-something gym-goer who’s actively trying to build muscle, not lose it. Getting enough can take some planning when I’m also keeping my carbs low and eating plant-based, so I like having recipes like this that make it easier to work protein into snacks and treats. Here, vanilla protein powder does double duty by providing much of the protein as well as most of the sweetness, while tahini adds creaminess and its distinctive sesame flavor. If your protein powder isn’t particularly sweet, you may want to add a little extra sweetener, and plain protein powder can also be used with pure monk fruit or stevia added to taste. These bars require no baking, just a brief stovetop step to dissolve and activate the agar in the coconut milk before everything is combined and left to set. I like the tahini with the chocolate, but another nut or seed butter should also work if sesame isn’t an option for you. You can also finish the bars with cacao nibs, sesame seeds, or another topping if you’d like some contrasting texture.

Description

Soft, mousse-like chocolate protein bars made with cocoa, unsweetened chocolate, creamy tahini, and coconut milk. Agar sets the mixture without baking, while the amount can be increased for a firmer, more durable bar.

Yield: 9 servings of 1 bar each, totaling 9 bars

Prep Time: 25 minutes | Rest Time: 3 to 4 hours

Equipment Required: 7-inch (18cm) square cake pan or 9x5-inch (23x13cm) loaf pan

Storage: refrigerated for up to 5 days. Can also be frozen.

Ingredients

Cooking Mode Disabled

Instructions

  1. Put the tahini in a medium-sized mixing bowl.
  2. Combine the cocoa powder and protein powder in a small bowl.
  3. In another small heat-safe bowl, put the baking chocolate, allulose, vanilla, and a pinch of salt.

  4. ​In a small saucepan, whisk together the coconut milk, agar agar powder, and ⅛ teaspoon salt. Bring to a low boil on medium heat. Reduce heat to low, and simmer for 5 minutes. Whisk occasionally and monitor and adjust heat if necessary to prevent boiling over.

  5. Meanwhile, line a 7-inch (18cm) square cake pan or 9x5-inch (23x13cm) loaf pan with parchment. Allow the parchment to hang over at least 2 sides of the pan for easy removal of the bars and/or use a loose-bottomed pan.
  6. Add roughly ½ cup + 2 tablespoons (150ml) of the coconut milk mixture to the chopped chocolate bowl and whisk until all chocolate chunks are melted. Add the remaining coconut milk mixture to the tahini bowl and whisk until fully combined.

  7. Add the protein powder and cocoa powder to the tahini-coconut milk mixture and combine thoroughly to form a smooth dough without any dry patches. I use a medium-sized silicone spatula for this.
  8. Transfer the dough to your lined pan and spread/press it into an even layer. I use the spatula and/or my hands for this.
  9. Cover the top of your bars with the melted chocolate mixture. Optionally, drizzle with a little tahini and sprinkle with cacao nibs and sesame seeds.
  10. Transfer the bars to the fridge to cool and set for 3 to 4 hours.
  11. Cut into 9 bars and enjoy chilled or at room temperature.

Notes

  • If you don’t have tahini on hand or are allergic to sesame seeds, another nut or seed butter (like almond or sunflower seed butter) should work well.
  • These bars are sweetened primarily by the protein powder. If your protein powder isn’t very sweet, you may want to add a bit of additional sweetener. If you're using an unsweetened or plain protein powder, a touch of pure monk fruit or stevia can help balance the flavor. I haven’t tested this with granulated sweeteners in the dough itself, so results may vary.
  • With 1 teaspoon of agar agar powder, the bars are quite soft and have a mousse-like texture. They still hold their shape at room temperature and can be eaten by hand. If you prefer a firmer, more durable bar, you can increase the agar agar—I've tested up to 1 tablespoon (3 teaspoons). Just note: the more agar you use, the faster the mixture sets, so you'll need to mix and shape the bars more quickly once the coconut milk mixture is added.

Frequently Asked Questions

Expand All:

Are these Chocolate Mousse Protein Bars vegan?

Yes! These bars are made with vegan ingredients, including tahini, coconut milk, and vegan protein powder, making them a great option for plant-based eaters.

Can I make these protein bars keto-friendly?

Yes! These Chocolate Mousse Protein Bars are keto-friendly because they are low in carbs and use a sugar-free sweetener like allulose. Perfect for anyone following a keto diet.

Do I need to bake these protein bars?

No, you don’t need to bake these bars. While the recipe requires a quick stovetop step to melt and combine the ingredients, there’s no oven involved. Just mix, refrigerate, and enjoy!

Can I store these protein bars?

Yes, you can store these bars in an airtight container in the fridge for up to 5 days. They can also be frozen. They’re perfect for meal prep or keeping on hand for a quick snack.

What toppings can I add to these protein bars?

Feel free to get creative! These bars are delicious on their own, but you can also top them with cacao nibs, vegan keto chocolate chips, sesame seeds, or even a little extra tahini for a decorative appeal.

What do you mean by "granulated sweetener of choice"?

The other most common keto-friendly granulated sweetener is erythritol. You can also use erythritol or allulose blends containing monk fruit or stevia to increase the sweetness to sugar-like levels. These will make for sweeter results. Using xylitol is also an option, but be aware that xylitol does contain some digestible carbohydrate, though product labels claim otherwise, and that xylitol is toxic to dogs, even in relatively small amounts.

What data is used to calculate nutritional data for this recipe?

When available, I usually use NCCDB data in Cronometer to calculate calories and macros. Occasionally, I use USDA data. For a few ingredients, however, I use label or custom data instead, even when NCCDB or USDA data is available. Typically, this is because I’ve found the product label data to differ substantially and consistently for those foods. Please note that NCCDB, USDA, and label data can change over time, so the nutritional calculations for the recipe, make at the time of writing, may differ from calculations made with current data.

For this recipe, I used label or custom data for the coconut milk (Aroy-D), agar agar powder (Now Foods), and protein powder (Vega Sport Vanilla).

The calorie and macro numbers on your recipes seem oddly uniform. Why is that?

Counting calories and macros can negatively impact mental health, so most numbers are rounded. Calories are rounded to the nearest multiple of 5, and macros are rounded to the nearest 0.5 g or whole number, depending on their value and use. For simplicity, naturally occurring sugar alcohols are counted as fiber unless the recipe includes added sugar alcohols.

What happened?

On July 4th, Weebly (my hosting platform) informed me that it was removing its services in my region and that my website would be unpublished as of September 27th. Fortunately, I had already been working on this new site and could have it finished by then. However, on July 15th, Weebly cancelled my subscription and notified me that my website would be unpublished imminently. I decided the best course of action was to transfer the domain name (www.keto4vegans.com) to my new unfinished site rather than have you encounter an error page and not have access to any of my content. 

Most of the content from my original site is already available here, and I’m working hard to redirect links, revise formatting, and add all the data needed for the new site’s fancy features to function at their full capacity.

Thank you for your patience while I revise content and work through the kinks.
