Ingredients for Single Serve Oatmeal Protein Cookie Recipe
This healthy single serve oatmeal protein cookie has just a 6 simple ingredients, and has no butter or oil and no sugar either!
- Rolled Oats
- Vanilla Protein Powder for healthy, whey protein cookie that’s also sugar free
I used Quest Nutrition Vanilla Milkshake protein powder here since its a whey-caesin blend and great for baking. - Unflavored Protein Powder to replace some of the flour (and carbs) in the recipe for a slightly low calorie protein cookie. Quest Nutrition whey-caesin again here.
- An Egg White for extra protein
- Some Cashew Butter: I used American Dream Nut Butter Dunk a Spoon Cashew Butter that’s higher in protein and lower in fat than normal ones!
ADNB also has a lot of other cashew butter flavors that would go perfect here. Code HAYLSKITCHEN gets you a discount here! - Baking Powder
And then of course the mix-ins:
- Fresh Cranberries
- Chocolate Chips; I use the chips from Lakanto here (HAYLSKITCHEN for a discount here too).
- Raisins or Dried Cranberries
- Walnuts
Tips for Single Serving Oatmeal Protein Cookie
This oatmeal protein cookie is a really easy dessert for one, but here’s some tips to get it perfect!
- Make sure you use Rolled Oats and NOT instant or quick oats! The latter are too fine and will make the mix to soggy.
- Use completely runny Cashew Butter so it mixes well with the oat mixture.
- Mix the ingredients completely so you get a thick cookie dough.
- Don’t let the oatmeal cookie mixture sit out too long or it will become too dense and make the cookie tough.

I am trying to find a oatmeal raisin protein powder recipe for my son in law that doesn’t have peanut butter, in it because he is allergic to nuts, coconut and bananas.
Can I substitute something else for the nut butter?
Hi Lisa! I’m so sorry about that.
You could try Tahini or Sunflower seed butter.
What can you use instead of protein powders? I know oat flour for unflavored.but what for vanilla?
Hi Heather!
I’m so excited you want to try out this recipe.
I haven’t tried this using anything outside of protein powder, but a good one might be 0 calorie monkfuit sweetener in place of the vanilla protein powder.
I’d recommend the Golden from Lakanto (https://www.lakanto.com/collections/sweeteners/products/lakanto-golden-sugar-free-sweetener); the code HAYLSKITCHEN gives you a discount too.
p.s. you might need to add extra oat flour in this case and judge by texture so the mixture isn’t too liquidy.
