These flourless Peanut Butter Protein Cookies are the perfect combination of sweet, salty, buttery, chewy, and crumbly. Just be warned – they are seriously addicting! Luckily, one cookie is only 82 calories, with 7 grams of protein, 2 grams of net carbs and NO SUGAR. Yes, you read that right! So besides being vegan, they’re sugar-free and keto-friendly (though no one will ever know).

Did you know? Peanut butter is about half monounsaturated fat, half omega-6 fat. While monounsaturated fat has been shown to increase insulin sensitivity, some studies suggest diets high in omega-6 can lead to inflammation. (source) So, just make sure you’re getting other fat sources besides peanut butter, especially those rich in omega-3’s!


Protein powder recommendations

These cookies use protein powder instead of flour, and what better protein to use than LIV Body’s Lean Vegan Protein! I went with Vanilla Birthday Cake flavor 😉 Their protein tastes amazing, which is very hard to find with vegan protein powders. LIV Body’s Lean Vegan Protein also has no artificial ingredients! Use my code NOEXCUSES for 20% all LIV Body products.

You may be able to substitute whey blends or whey concentrate in place of the vegan protein, but I have not tested it in this specific recipe. You can also omit the vegan protein and substitute half a cup of flour or more, until the dough is able to be rolled into balls.


Sweetener substitutions

For a little extra sweetness, I added my favorite organic stevia blend, but it’s optional. The protein powder is already sweet, so this is up to your personal tastes. I would suggest leaving out the sweetener if using maple syrup, honey, or pancake syrup in this recipe.


Other substitutions

The only other main ingredients are natural creamy peanut butter, VitaFiber syrup (can sub sugar free pancake syrup, maple syrup, or honey), and vegan buttery spread. If you’re using sugar free pancake syrup, maple syrup or honey, leave out the additional sweetener or cut back since these are sweeter. Of course, you can use regular unsalted butter if not vegan.

My favorite way to enjoy these cookies is to sandwich two together with a teaspoon of peanut butter and a teaspoon of low sugar jam! So good.

Thai Chicken & Vegetable Coconut Curry

November 10, 2023

This Thai Chicken & Vegetable Coconut Curry is a scrumptious meal prep idea for all you Thai fans out there! Thai cuisine is one of my favorites, so I was stoked with how authentic this simplified thai chicken coconut curry (“kaeng phet”) came out. It’s definitely a “cheater” recipe in that I used red curry paste instead of dried chilies and all the individual curry spices. But hey, it tastes amazing and comes together easily which is what I was after! I absolutely love this served over fragrant basmati rice. You could also use riced cauliflower for a low-carb version.
