I have been wanting to make protein rice crispy treats with collagen for awhile now. Collagen makes things gooey, which worked so perfectly in these peanut butter rice crispy treats. Of course, I slathered with chocolate ganache because I need chocolate in my life 😉 Instead of using marshmallows and corn syrup, I used nut butter and all-natural sugar free pancake syrup for NO added sugar. That said, maple syrup or honey would work great in this recipe, too!

Did you know? Collagen supplementation appears to increase bone mineral density and help protect against osteoporosis (source).


Making the rice crispy base

For the base of this recipe, I picked up some brown rice crisp cereal with no added sugar. Of course, Rice Krispies will work too, or any crisp rice cereal. Next, I melted some creamy peanut butter and sugar free pancake syrup, (can use maple syrup or honey) over the stovetop until melted.

Adding the collagen

After my peanut butter was completely melted, I whisked in some LIV Body Flavorless Marine Collagen. I love that this collagen is highly bioavailable with no flavor (perfect for baking). You can use my code “NOEXCUSES” for 20% off all LIV Body products (including their skin care) here:

You can use as little collagen as you want (or none at all) in this recipe – but the maximum I’ve been able to incorporate is 120 grams.


Adding remaining ingredients

Along with the collagen, I whisked in some calorie-free sweetener, pure vanilla extract, and sea salt. If you can’t do peanut butter, try smooth almond butter, cashew butter or sunflower butter!

Next, I combined my peanut butter mixture with my crisp rice cereal in a large bowl, folding with a spatula until well combined. I then pressed the mixture into a baking dish lined with parchment and placed in the fridge for half an hour.


Making the chocolate ganache

To make my ganache, I whisked two tablespoons of hot unsweetened cashew milk into two ounces of dairy-free dark chocolate chips in a small mixing bowl (any milk will work). Finally, I slathered this onto the bars and placed them back in the fridge for another 15 minutes or so. The ganache topping is optional but really delicious! I bet peanut butter melted with the chocolate would be amazing, too.


Anyway, here’s the printable recipe for these Collagen Protein Rice Crispy Treats! I hope you’ll rate and comment below if you try them 🙂
