These Wow Butter Sandwich Cookies deliver all the delicious flavor of peanut butter and chocolate without any of the worry. These incredible cookies are filled with layers of wow butter and chocolate making them the perfect dessert for those with allergies. In addition, they're gluten free, egg free, nut free and easily dairy free (vegan)!
In a medium bowl, whisk together the gluten free flour and the baking powder. Set aside.
In a large bowl of an electric mixer or in a large bowl using a hand held mixer, beat together the wow butter, sugar and butter (or vegan baking stick) until smooth. About 2 minutes.
In a separate small bowl, using a spoon, mix together the cornstarch and water with a spoon until it is thin and watery. It will be thick and tacky at first.
On low speed, beat the cornstarch water mixture into the wow butter mixture along with the milk of choice.
Gradually add the gluten free flour mixture, beating to combine.
Once combined, remove the dough from the bowl and shape it into a flat disk.
Wrap the disk in plastic wrap and refrigerate for at least 30 min.
When the dough is almost done chilling, preheat your oven to 350 degrees Fahrenheit.
Take the dough out of the fridge and pinch off about 1 inch and roll into a ball.
Pour the granulated sugar into a small bowl. Drop the 1 inch dough balls, one at a time, into the bowl of granulated sugar and roll until coated.
Place the sugar coated dough balls about 1-2 inches apart on a baking sheet lined with parchment paper.
Bake the cookies for exactly 9 minutes.
As soon as they come out of the oven, you will notice they didn’t flatten much. Take a fork and push down on them and then do the same thing in the other direction so you create a nice checker board pattern on the tops of the cookies. Make sure not to flatten them too too much.
Let the cookies cool completely on the baking sheets before moving them. Since there is no egg, if you try to move them while they’re still warm, they will fall apart.
Now for the wow butter filling: Beat all the wow butter filling ingredients on medium speed until they are super smooth. About 2 minutes.
Using a butter knife or small frosting spatula, frost the bottom of one cookie and make sure you pick another cookie to leave next to it so when we’re all done you have enough to assemble the sandwiches.
Do this with half the cookies, making sure to spread it on the bottom of the cookie not the pretty top. The tops will be the outside of our sandwiches.
Let these solidify a few min while we make the chocolate filling: In a medium microwave safe bowl, heat the chocolate chips and the butter or vegan baking stick in 15 second increments, stirring after each time until melted. Do not rush this process because if you overheat the chocolate, it will seize up and basically not be usable.
Once again, using a butter knife or small icing spatula, spread the melted chocolate right on top of the wow butter filling and then place another cookie on top of the wet chocolate, making sure the bottom of the cookie is on top of the chocolate. You want both bottoms of the cookies to be touching the fillings and the nice tops of the cookies to be on the outside.
Serve and enjoy! Let solidify a bit before storing in an airtight container.
