Dark Chocolate & Blackberry Collagen Shortbread Bars

Reap the benefits of collagen with these naturally sweetened, gluten and dairy free dark chocolate & blackberry collagen shortbread bars! When I first used this flavor of Vital Proteins, I knew it was too good not to bake up in a special dessert! I often put collagen in my baked goods to give them that extra boost of protein and collagen peptides! You can read more about how and why I incorporate collagen into my daily routine here.

This flavor of Vital Proteins collagen is a new one on my radar, and lately, I’ve been mixing it with a 1 cup of almond milk, some fresh blackberries if I have them, and a handful of greens. I drink it after a workout and it feels like I’m having a fun treat, while getting the protein I need to refuel my body, and the collagen I need to replenish my skin! These dark chocolate & blackberry collagen shortbread bars feel like that too with their crispy crumble on top! Since they are only sweetened with maple syrup and fresh blackberries, you can feel good about having them around as treats!

You can grab your own tube of this Dark Chocolate & Blackberry collagen here on my Amazon list, and be sure to check out some of my other Vital Proteins like their original collagen, and matcha collagen!

The almond flour and coconut flour come together to create a shortbread like you’ve never had before. Traditional shortbread uses butter, which I’m all for (especially grass-fed), but here coconut oil makes the perfect substitute. Blackberries all on sale all over my grocery stores right, now and I just love these juicy, tart berries in every way, shape and form. They’re a great source of vitamin C, fiber and lots of antioxidants.
