This keto Dark Cacao Sea Salt Collagen Fudge has become a weekly occurrence at our home! So far I’ve made a cookie dough version, a peanut butter version, and now this dark cacao sea salt version. I honestly couldn’t tell you which I like best, but this one is probably the least sweet and definitely the most chocolatey. It’s hard not to be addicted to that sweet and salty combo! Just keep in mind that, even though this recipe is made with healthy ingredients, you’ll still need to exercise moderation. Each 2″ square is about 100 calories, full of healthy fats and protein!

One of the concepts I teach my clients is moderation – you’re not going to ruin your progress with one cookie, one piece of chocolate, or one slice of pizza. What will derail progress is the “all or nothing” mindset (“well, I blew it so I might as well binge all day and start fresh tomorrow”).


Collagen recommendations

To add muscle-building protein to these rich fudgey squares, I used unflavored collagen protein powder. Collagen improves skin elasticity and appearance, joint health, gut integrity, and overall feeling of fullness (more on that here). LIV Body Marine Collagen is one of my favorites, because it’s highly bioavailable and rich in type I collagen (the most essential form of collagen). You can use my code “NOEXCUSES” for 20% off all LIV Body products!

If you don’t have collagen, you can leave it out and omit the milk, OR substitute half as much of another protein powder (40 grams whey, whey-casein blend, or plant-based protein) and adjust the amount of milk as needed. This doesn’t work in all recipes, but no-bake recipes are more forgiving!


Sweetener substitutions

For added sweetness without the extra sugar, I used Pyure Organic Stevia Blend, a calorie-free blend of stevia and erythritol that’s twice as sweet as sugar. A nearly identical substitute would be Truvia Natural Sweetener. If substituting baking stevia, granulated erythritol, or a granulated sugar like coconut sugar, you will need about twice as much (three-quarter cup) to achieve the same level of sweetness. If you use sugar, maple syrup, or honey, this fudge will no longer be “keto.” If using stevia extract or drops, please refer to the brand-specific conversion chart.


Other substitutions

I used special dark unsweetened cocoa powder to achieve a rich, dark chocolate flavor. This is basically a combination of dutched and natural cocoa, but any unsweetened cocoa or cacao powder will work here!

The only other ingredients you’ll need are creamy almond butter, coconut oil, unsweetened almond milk, and vanilla extract. Make sure to use “refined” coconut oil if you don’t like the faint taste of coconut. You can also swap the coconut oil for vegan buttery spread, ghee, or unsalted butter. For a more decadent version, try two tablespoons of dark chocolate chips instead of the coconut oil! Feel free to sub the almond butter for creamy cashew butter or sunflower seed butter, too. The unsweetened almond milk can be substituted for any milk you prefer.


Oh, and I decided to add extra dark chocolate chips on top! Also, I highly recommend doubling this recipe and using an 8″x8″ brownie pan… this fudge will go fast and you’ll wish you made more 😉

Here’s the printable recipe for my Dark Cacao Sea Salt Collagen Fudge (Keto)! I hope you’ll rate and/or comment below if you try it 🙂

    Thai Chicken & Vegetable Coconut Curry

    November 10, 2023

    This Thai Chicken & Vegetable Coconut Curry is a scrumptious meal prep idea for all you Thai fans out there! Thai cuisine is one of my favorites, so I was stoked with how authentic this simplified thai chicken coconut curry (“kaeng phet”) came out. It’s definitely a “cheater” recipe in that I used red curry paste instead of dried chilies and all the individual curry spices. But hey, it tastes amazing and comes together easily which is what I was after! I absolutely love this served over fragrant basmati rice. You could also use riced cauliflower for a low-carb version.
