Frosting

Instructions
 

  • Pre-heat the oven to 350 F (177 C).
  • In a large bowl, combine the water, brown sugar, vanilla extract, and ground flax.
  • In a separate bowl, whisk together the pea protein, rice flour, cocoa powder, salt, cinnamon, xanthan gum, baking soda and baking powder.
  • Add the pea protein mixture (dry ingredients) to the wet ingredients. Mix together well.
  • Roll the dough into balls and flatten them out a bit. Place them on a parchment paper lined baking sheet. You should end up with 10 cookies.
  • Bake for 9 – 10 minutes.
  • While the cookies are baking, make the frosting. In a bowl, mix the avocado oil and powdered sugar together. I just use a fork until it reaches a frosting-like texture – think Oreo filling.
  • Once the cookies are baked, allow them to cool for at least 4 hours.
    Baked goods made with pea protein sometimes leak water within the first few hours after coming out of the oven, so it's important to allow them to fully cool and reach equilibrium before adding the frosting (because the frosting will melt if it touches water and you'll be feeling a lot like the sad little racoon who put his cotton candy in water).
  • Frost 5 of the cookies with the frosting, and place the remaining 5 cookies on top.

Reduced Sugar Option

I’ve had a few people say that they love GreenBites Sandwich Cookies, but that they’d like to see a recipe that they can easily make at home for cheaper. So, this is my gluten-free protein chocolate sandwich cookie offering for you guys that want a more affordable option!

I made this one with pea protein as the main protein source, because it’s a cheap baking option that is also gluten-free. If you’re looking for some other gluten-free high protein snacks, be sure to check out my Rice Crispy Treats and Chocolate Crunch Bar recipes.

If you don’t have a gluten-intolerance and maybe don’t like pea protein, I also have this protein chocolate sandwich cookies that use vital wheat gluten instead.

Ingredients

  • Pea Protein Powder – I used pea protein powder for this recipe, specifically the one shown below. Baking with protein powders can be kind of weird and they all cook a little differently, so I would not recommend using a protein powder other than pea protein, because it I can’t guarantee it will turn out like the cookies shown.
  • Sweet White Rice Flour – this is a gluten-free flour option, and it provides a little more structure to the cookies than the pea protein powder can on its own.
  • Xanthan Gum – this is a thickening agent and stabilizer. Baked goods made with pea protein have a tendency to weep (drop water) after they cool off. Xanthan Gum and Rice Flour help retain the moisture and prevent it from dropping out.

  • Flax Seed – this is my personal favorite egg replacement. It also has a decent amount of protein and fiber.
  • Baking Powder
  • Baking Soda
  • Salt – adjust to taste
Flaxseed meal, salt, baking soda and baking powder.
  • Brown Sugar – if you’re reducing your sugar intake, you could replace this with a 1:1 sugar alternative. I have had good luck with monk fruit personally.
  • Cocoa Powder
  • Vanilla Extract
  • Cinnamon
Cocoa powder, vanilla, cinnamon and brown sugar.
  • Avocado Oil – this is my oil preference because it’s fairly flavorless. If you don’t have avocado oil, you could also use Canola oil.
  • Powdered Sugar – if you’re trying to reduce your sugar intake, you could swap this with a 1:1 sugar alternative; I’ve had good luck with monk fruit.

Instructions

  • Pre-heat the oven to 350 F (177 C).
  • In a large bowl, mix together water, brown sugar, ground flax and vanilla extract.
  • In a separate bowl, whisk together pea protein powder, rice flour, cocoa powder, xanthan gum, baking soda, baking powder, salt and cinnamon.
  • Add the dry ingredients to the wet ingredients and mix together well (I use a spatula). Your mixture should look like this.

  • Divide the cookie dough and roll into little balls (should be about 2 – 2.5 tablespoons each).
  • Flatten the cookie balls and lay them out on a parchment paper-line baking sheet. They expand a bit so make sure they have a little space in between them.

  • Bake for 9 – 10 minutes.
  • While the cookies are baking, get a medium-small bowl and mix the powdered sugar and avocado oil together. I use a fork for this step. Your frosting should be about the consistency of the frosting used in Oreo cookies.

  • Once the cookies are done baking, allow them to cool for at least 4 hours (longer if possible). Baked goods made with pea protein powder (specifically) have a tendency to “weep” or leak water after they have cooled off. We have used xanthan gum and rice flour in this recipe to counteract that, but it still happens a little. So just leave these on your counter for several hours until they’ve essentially stabilized; you may even throw in the fridge for a couple hours as well for good measure.
    • This step is vitally important and should definitely be done before adding the frosting to the cookies. Because the frosting is a powdered sugar base, if water leaks into it, it will melt like Frosty at the end of the movie. So just trust me on this.
    • If you’re going to eat these immediately, you don’t have to wait to frost them.

  • Spread the frosting onto 5 of the cookies. It’s thick frosting so you really need to do some smooshing. I honestly just use my fingers when I make them for just me and my partner. If I was making them for you, I would obviously spread it with a spoon or knife, because I’m not a monster.
  • Put the remaining cookies on top of the frosted cookies and enjoy!
