Ever since I discovered vegan marshmallow fluff made with aquafaba, I have wanted to make something fluffernutter. Mostly because I have never actually had anything fluffernutter...and it is a fun word to say, and the combination sounds delicious to someone craving salty and sweet. Also, I have had really good luck with my marshmallow fluff, since it is easier to make than something you would have to bake made with the meringue.
Fluffernutter Sandwich Cookies [Vegan, Gluten-Free]
- 1 Tbsp ground flaxseed
- 3 Tbsp filtered water
- 1 cup coconut sugar
- 3/4 cup peanut butter
- 1/4 cup coconut oil, warmed to liquid
- 1 tsp pure vanilla extract
- 1 1/4 cups gluten-free all purpose flour or quinoa flour
- 3/4 tsp baking soda
- 1/2 tsp baking powder
- 1/2 tsp sea salt
- 1/2 cup aquafaba (the liquid from cooked or canned chickpeas. If you are using liquid from the cooked, you want to make sure it is thick, not watery)
- 1 1/2 tsp xanthan gum or guar gum
- 1/2 cup powdered xylitol, maple sugar or coconut sugar
- 1/4 tsp sea salt (if your chickpea liquid has no salt)
- 1/4 tsp pure vanilla extract
- In a small bowl, whisk together the flax seed and water. Place the bowl in the fridge for 15 minutes, this is your flax egg.
- In a large bowl, with a wooden spoon, mix together the sugar, peanut butter, coconut oil, vanilla and flax egg, until smooth. Then mix in the flour, soda, baking powder, and sea salt in until the mixture is smooth.
- Preheat the oven to 375F degrees. Line a sheet pan with parchment.
- Shape the cookie dough into 2 inch balls, place on your baking sheet a few inches apart and flatten with a fork, like you would with peanut butter cookies.
- Place in the oven and bake at 375 for 12 minutes or so, until lightly browned and set. Allow to cool completely on a rack.
- Meanwhile, In a food processor (which is what I used, or you may use a stand mixer with a whisk attachment), whip up the chickpea liquid until it has reached pretty stiff peaks. This will take about 2 minutes in the food processor. Add the guar gum and cream of tartar and process until incorporated. Add the sea salt and sugar and with the motor running, a little at a time through the feed tube (so you do not deflate it), then allow to process until the sugar is completely dissolved and the meringue is smooth, shiny and thick. Add the vanilla, and blend until uniform in color.
- Flip half the cookies upside down, and spread some of the marshmallow fluff onto each one. Top with another cookie.
If you do not want to make these gluten free, you can use whole wheat pastry flour. If using the coconut sugar or maple sugar, it will turn your marshmallow fluff light brown. Xylitol is toxic to dogs the same way chocolate is, so do not let your dog get ahold of this marshmallow fluff.
