Oatein Peanut Butter Cookie Sandwich

Oatein Peanut Butter Cookie Sandwich

“All baby sandwiches dream of becoming peanut butter cookie sandwiches when they grow up.⠀Only the strongest become true Oatein Nut-butter Cookie sandwiches.” 

- Winston Oathill 

The ultimate lazy day treat, these peanut butter filled cookies are an absolute smasher when you want to go a bit overboard and want zero hassle. Rich in protein and high quality peanut fats, this recipe is a real winner. While it certainly isn’t ‘guilt-free’ it’s got much more nutritional value than your average high-street snack. 

In terms of filling, you can opt for a high protein peanut butter spread. Whatever you choose, I’ve found a smooth peanut butter works best as it gives a lovely textural counterpoint to the slightly chewie, crumbly cookie. There’s nothing stopping you using a chocolate spread, but err on the side of low sugar unless you need (or deserve) the boost to your blood sugar levels.

Each Oatein cookie contains about 16.5g of protein so you’re looking at 33g for the whole experience, which is quite a big serving! Cut it in half and share it with your bestie, or save the other half for later,  I’m sure it’ll go down very, very well indeed!


  • 2 Oatein Cookies (We’d recommend Milk Chocolate)
  • Peanut Butter or Chocolate Spread - Try to contrast the flavour with the chocolate. Chocolate on chocolate can be a bit samey!


This one couldn’t be simpler:

  • Get two cookies. 
  • Lather the bottom of one cookie generously, (VERY generously!) with peanut butter. 
  • Place the second cookie face up on the layer of thick peanut butter.
  • Enjoy!
