A giant single S’mores Protein Cookie recipe made with oat flour, sweetened with protein powder and topped with chocolate and marshmallow! Single serving baked protein cookie is a healthy dessert for one and will leave you wanting s’more.

I’ve really gotten into the whole single serve protein cookie thing recently, and even more so because so many people were interested in the last one I made; A single serving chocolate protein cookie.

I’d actually had my eye on some sugar-free marshmallows for quite a while – even reached out to a brand to ask if I count try some – but nothing worked out.

I just gave in with the regular ones because it would also start to get me to eat a little less restrictive.

So of course the first thing I had to make with marshmallows had to be a s’mores inspired recipe and what better than a giant single serve s’mores protein cookie?!

Ingredients for Single Serving S’mores Protein Cookie Recipe

This healthy s’mores protein cookie recipe has just a few simple ingredients, and is eggless, has no butter or oil and no sugar sugar either!

Gluten Free Baking Flour – or regular or whole wheat pastry flour
Vanilla Protein Powder for high protein cookie recipe, and also replace the sweetener.
I use Quest Vanilla.
Unflavored Protein Powder I use the Multipurpose mix from Quest Nutrition.
Unsweetened Applesauce
Almond Milk to give the soft cookie a slightly cakey feel, and keep it dairy free.
Baking Powder

And then of course.. Hershey’s Chocolate and Mini Marshmallows.

How to make a Single Serve Smores Protein Cookie

To make one of these smores protein powder cookies, you mix the protein cookie dough, spread it out and just bake!

Preheat oven to 350°F and line a baking pan with parchment paper.

Mix cookie ingredients – flour, vanilla protein powder, unflavored protein powder, applesauce, almond milk and baking powder – in a bowl.
Add almond milk a little at a time so mix doesn’t get too runny.

Transfer half cookie dough onto the baking sheet and shape it into a big giant chocolate protein cookie for one.
Place most chocolate and marshmallow in middle.
Cover with remaining cookie dough.
Use wet fingers to shape into cookie.
Place baking pan in freezer for about 1 hour.

Bake for 7 minutes, then Broil 1 min.
You might need a minute extra; make sure the top is dry to touch, and marshmallows slightly toasted.
Don’t over-bake the cookie; Let cook until the top is just cooked and soft; too long and you might end up with a rough and dry texture.
