Ingredients for Mexican Hot Chocolate Protein Cookie for One

This healthy Mexican hot chocolate protein cookie recipe has just a few simple ingredients, and is eggless, has no butter or oil and no sugar sugar either!

Oat Flour – You can make your own by blending rolled oats in a high speed blender
Chocolate Protein Powder for high protein cookie that’s also sugar free.
I used Quest chocolate protein powder since it’s sweetened with Stevia.
My other go-tos are ProteinWorld Whey and ProteinWorld Slender Blend (code HAYLSKITCHEN gets you a discount on both.
Unsweetened Cocoa Powder or Cacao Powder
Peanut Butter Powder, also known as Powdered Peanut Butter. I recommend Lakanto for a sugar free version (the code HAYLSKITCHEN gives you a discount). Or you could use the one from PbFit too.
Non-fat Greek Yogurt contributes to the oil-free part of these chocolate protein cookies since it adds the moisture, and also extra protein
Almond Milk to give the soft cookie a slightly cakey feel, and keep it dairy free.
Mexican Hot Chocolate Spices: Cinnamon, Nutmeg and Cayenne Pepper
Baking Powder

And then of course..

Mini Marshmallows for the hot chocolate cookie effect!
Chopped Chocolate (or Chocolate Chips): I’d recommend the sugar free ones from Lakanto. The code HAYLSKITCHEN works here too.

How to make a Single Serve Hot Chocolate Protein Cookie

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

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

Mix your ingredients – oat flour, protein powder, cocoa powder, peanut butter powder, almond milk, Greek yogurt, cinnamon, nutmeg, cayenne pepper and baking powder – in a bowl.

Transfer ⅔ protein cookie dough onto the baking sheet in a round cookie shape.

Place marshmallows in the middle to form the gooey chocolate center of the protein cookie.

Cover with remaining chocolate protein cookie dough and shape it into a giant hot chocolate protein cookie for one. Some peeping marshmallows are okay so you have for the perfect Mexican hot chocolate cookie with marshmallows on top.
Top with some chopped chocolate.

Bake for 12 min. You might need a minute extra; make sure the top is completely dry to touch.

Let it cool a bit, and indulge!

Tips for Mexican Chocolate Protein Cookie

Make sure the milk and yogurt are at room temperature so you have a smooth mixture.

Use ⅔ mixture below and ⅓ above marshmallows; This is so that the heat does not melt them too soon.

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.

Alternates for this Healthy Mexican Hot Chocolate Cookie with Marshmallows

I recommend making this Mexican chocolate protein powder cookie using the ingredients and products listed – since it gives the best results.

If you need other options for the flours and such, here’s some alternatives:

Oat flour: Use Whole wheat pastry flour or even all purpose flour. A 1:1 Gluten-free all purpose baking flour would work too. Go by the weight for these substitutions.
You can try to use almond flour; I’m a little hesitant about this one, so let me know if you try it.
Chocolate Protein Powder: Use Vanilla Protein powder instead of chocolate, or
1:1 Zero Calorie Sugar Substitute; I use Lakanto, to keep this recipe sugar free; (code HAYLSKITCHEN for a discount here too)
Peanut Butter Powder: Use real peanut butter, but reduce almond milk to 2 tbsp
Regular non-dairy milk to replace almond milk.
Coconut Yogurt in place of Greek Yogurt

A Vegan Cookie Recipe

This single serve chocolate marshmallow protein cookie recipe has no eggs and uses almond milk, so can easily be made Vegan too.

For the perfect high protein Vegan Mexican hot chocolate cookie, make sure you use a plant based protein powder; ProteinWorld has a Vegan protein blend that would be great here (HAYLSKITCHEN for the discount here too).

You also want to use coconut yogurt, dairy free chocolate and Vegan marshmallows here, or just leave the marshmallows out. You still get an amazing spicy chocolate protein cookie!
