With Christmas rounding the corner, I just had to re-make these Frosted Protein Sugar Cookies! They deserved better photos and I also tweaked the cookie and frosting recipes just slightly to make them even more irresistible. Despite being called “sugar” cookies, these cookies actually have ZERO sugar! Don’t worry, they still have all that sweet buttery flavor, a tender, soft-baked texture, and the best sugar-free vanilla icing. And guess what? You can eat all six cookies for just under 440 calories (a couple didn’t make it to the photo shoot)!

If you like low-calorie vegan cookies that taste amazing, you might also like my Chocolate Peppermint Protein Cookies, Protein Jam Thumbprint Cookies, White Chocolate Cranberry Protein Cookies or my favorite Protein Gingerbread Cookies!

Protein powder substitutions

This cookie recipe uses LIV Body Lean Vegan Protein in Cake Batter, which is a plant-based pea protein powder. I love that it’s free of artificial ingredients with added super foods and still tastes awesome! You can use my code “NOEXCUSES” for 20% off all LIV Body products 😉

I’ve also tested a pea and pumpkin blend as well as soy isolate. You can *try* whey or casein in this recipe, just reduce the baking time by 3-4 minutes so they don’t dry out. Better yet, I actually have a sugar cookie recipe specifically for whey!

Flour substitutions

I used gluten-free baking flour in this recipe, but feel free to substitute all-purpose flour, brown rice flour, cake flour, cassava flour (Paleo), oat flour (oats blended into flour), sorghum flour, spelt flour, or whole wheat pastry flour. You can also swap the protein powder for one-quarter cup (30g) of additional flour.

Sweetener substitutions

To sweeten these cookies, I used my favorite organic stevia-erythritol blend. It’s calorie-free and twice as sweet as sugar with no bitter aftertaste. If using baking stevia, granulated erythritol or regular sugar, you will need to use twice as much to get the same amount of sweetness.

Other substitutions

For richness and buttery flavor, I used a combination of vegan buttery spread and cashew butter. You can use regular unsalted butter if you’re not vegan! Aquafaba, or the liquid from canned chickpeas, makes a great stand-in for egg white, but vegan egg replacer, or one egg white will also work. Finally, pure vanilla extract makes these cookies extra rich and flavorful.

Sugar free icing

For the icing, I used powdered monk fruit sweetener (confectioner’s erythritol or powdered sugar will also work), unsweetened almond milk (any milk will do), vegan buttery spread, and allulose syrup.

Allulose syrup is naturally derived from figs, raisins, jackfruit, and kiwi. It’s sugar-free, gluten-free, vegan, kosher, and non-GMO! Allulose syrup does have carbs, but it’s technically calorie-free and has no impact on blood sugar. You can also use agave syrup, light corn syrup, or simple syrup as they’re clear and neutral in flavor (you’re using a very small amount).

    I love a good waffle and these Sweet Potato Collagen Protein Waffles did not disappoint! They've got a tender, moist texture thanks to the sweet potato and are also gluten-free, dairy-free, and low in sugar! I love these waffles topped with pomegranate, coconut yogurt, and maple syrup... but they're really a blank canvas for whatever you enjoy!

    This healthy Slow Cooker White Chicken Chili is made with dried whole beans not canned! I also used raw chicken breasts - no more hunting for rotisserie chicken! All you have to do is layer everything in a crockpot or slow cooker, then leave overnight for the best white chicken chili the next day.

    Pumpkin and white chocolate is one of my favorite fall flavor combos! These Pumpkin Pie Protein Truffles taste like pumpkin pie rolled into balls and smothered with rich white chocolate. They're also gluten-free, dairy-free, vegan, and easily made low carb and keto. So irresistible I've made two batches already! Literally cannot distinguish these from full sugar treats.
