This week for meal prep I made the hubby this keto chocolate protein fudge for dessert! I have made a lot of protein fudge variations with whey, but I have to say this is THE closest to real fudge in taste and texture I have found. It literally melts in your mouth and has that hint of chewiness on the outside. Not to mention, that decadent chocolate flavor! It’s rich without being too sweet. You might also like my Cookie Dough Protein Fudge 😉

Did you know? Muscle protein synthesis peaks about 3 hours post-workout, so we need to get 2.5 grams of leucine (along with the other BCAAs) within this timeframe to max out muscle growth.1-3 Consuming 25-30 grams of whey protein post-workout should accomplish this!

For this fudge, I used my husband’s favorite M.A.N. Sports ISO-Protein in Chocolate Milk (use code “NOEXCUSES” for 20% off). As you all know, I can’t tolerate whey anymore, so I stick to non-dairy protein powders. You can totally substitute collagen or a vegan protein powder in this recipe, but you will have to adjust the amount of milk in order to get a thick (but pourable and spreadable) mixture. Your fudge mixture should easily pour out of your mixing bowl into the pan, but require some spreading with a spatula to level out into the corners of your pan.

I usually use some sort of nut butter in my protein fudge recipes, but this time I went with organic refined coconut oil to keep the carbs down. Don’t worry, refined coconut oil has a neutral flavor with no coconut taste! If you choose to substitute nut butter, you may need a couple tablespoons extra milk to get the right consistency. I use unsweetened almond but any milk will do! You can also try a vegan buttery spread or regular unsalted butter in place of the coconut oil.

The only other ingredients are unsweetened cocoa powder, salt (optional), 70% cacao dark chocolate (can sub nut butter) and vanilla extract. Walnuts are optional, but I like my fudge with some texture.

Here’s the printable recipe for this keto chocolate protein fudge! I hope you will rate and comment below if you try it 🙂

    Hey Austin! The “cook time” is actually referring to the time on the stovetop melting the ingredients together. It may even take less time for you!

    Instructions says “cook time:5 minutes” but doesn’t mention the ideal temperature for the oven.

    Hi Lisa! Yes you could subtract a tablespoon or two of the protein and replace it with cocoa powder. I would also add sweetener, start with one third cup of sweetener that measures 1:1 like sugar (erythritol or monk fruit blend) then adjust from there if you like more sweetness :)

    Hi! I would love to make this protein fudge, but I only have unflavored whey protein. Should I adjust the protein powder and cocoa powder required to compensate?

    If you love brownies like I do, this Skillet Protein Brownie is a satisfying, dairy free option with plant based protein. It has a moist, fudgey texture that's delicious on its own, and even better with dairy free vanilla ice cream and berries! This shareable treat is low in sugar and high in fiber with a whopping 20 grams of protein per serving! It's the perfect healthy dessert (or even breakfast).

    This Healthy Chicken Pad Thai has the perfect balance of tangy, sweet, savory, and salty with tender chicken, thick rice noodles, mung beans, crunchy peanuts, and colorful veggies. So good! It's also macro-friendly, gluten-free and dairy-free. If you need this vegan, omit the scrambled egg and use crispy baked tofu instead of chicken!

    These Mediterranean Turkey Stuffed Peppers are high on the flavor charts and very filling for the calories. These peppers will not only satisfy your tastebuds, but your hunger, too! I love the combination of seasoned ground turkey, lemon parsley quinoa, and goat cheese. It’s one of those things I can eat all week and not get sick of (perfect for meal prep). The kids gobbled these too, believe it or not! Make these vegan using spiced chickpeas and vegan mozzarella.
