BOOM. 🔥🔥🔥 I’m posting these Vanilla Protein Blackberry Crumble Bars in honor of the rebrand over at Equip Foods (formerly pureWOD), my favorite protein brand. These are made with Equip’s vanilla Prime Protein, which I love because it has only four ingredients: beef isolate, coconut milk powder, vanilla, and stevia. No gluten, dairy, whey, soy, hormones, antibiotics, fillers, artificial sweeteners, or preservatives.

Maybe the idea of putting beef in your Vanilla Protein Blackberry Crumble strikes you as a bit off. Don’t worry, Prime Protein doesn’t taste like beef at all! I personally think it tastes like sweetened condensed milk, which makes it an interesting ingredient to experiment with in baking.    

I won’t label these as keto per se, but they definitely did not kick me out of ketosis when I ate them. They’re as low in carbs as I could make them, using coconut flour, blackberries (6 grams of carbs per cup versus 17.4 grams in a cup of blueberries), eggs, oil, vanilla, lemon, and the sweetness of the stevia in the Prime Protein itself.

I even experimented with a coconut drizzle: 1/2 cup coconut butter + 4 tbsp coconut milk + stevia to taste. Really pretty in combination with extra lemon zest. 🍋 🍋 🍋

I honestly don’t know if this recipe will work with other protein powders. I have heard that plant-based protein powders perform very differently in baking than ones made of whey, or beef (such as Prime Protein). Prime Protein is actually the only protein powder I’ve ever tried to bake with, so, let me know if you try it with another kind of protein and it works well!
