Perfect High Protein Caramel Marshmallow Bars made with protein powder and peanut butter powder. Caramel Marshmallow Protein Bites are perfect for a healthy, low sugar and low fat snack or post workout treat.

This was actually a very random recipe here; I tried a protein rice krispie cookie by melting some marshmallows and peanut butter in the microwave and it turned out so good I adapted it to make this.

The caramel and marshmallow flavor really go so well together, but somehow the result doesn’t turn out too overpoweringly sweet either. The perfect balance of sweetness!

Ingredients for Caramel Marshmallow Bars

These caramel marshmallow bars are made with protein powder, peanut butter powder and a sugar free caramel syrup for a healthy recipe!

Mini Marshmallows
Creamy Peanut Butter – I use the white chocolate flavor from American Dream Nut Butter (discount code HAYLSKITCHEN). They have a bunch of other flavors that would go well here too.
Rice Krispies Cereal
Vanilla Protein Powder for high protein cookie; I used Quest.
Unflavored Protein Powder: The Quest Nutrition whey-casein again here.
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.
Sugar free Caramel Syrup for sugar free caramel marshmallow protein bar!
I use the sugar caramel syrup from Lakanto (code HAYLSKITCHEN gets you a discount)

And for the chocolate topping:

Sugar Free White Chocolate – I use the white chocolate bar from Lily’s here. They also have white chocolate chips that would work too.

Alternatives for Healthy Caramel Marshmallow Bites:

I made these sugar free and low fat healthy caramel marshmallow bites with this particular ingredient list, but here’s some options to choose from.

Peanut Butter Powder: Use 3 Tbsp + 1 tsp Creamy Peanut Butter, but also reduce the caramel syrup to maybe 2½ Tbsp.
Unflavored Protein Powder: Oat flour or almond flour

Sugar free Caramel flavor Syrup: Regular caramel syrup, but they won’t be a low sugar sugar recipe anymore.
White Chocolate flavor Peanut Butter: Regular Peanut Butter, Almond Butter, Hazelnut Butter or even Tahini (be sure to add a bit of sweetener in this case)
Sugar-free White Chocolate: Regular white chocolate works

Vegan High Protein Crispies

Use a plant based protein powder to get a Vegan peanut butter protein rice krispie treats; I recommend KOS Vanilla and KOS Unflavored protein powder.

You also want to make sure you use Vegan marshmallows and dairy free white chocolate.
