Preheat oven to 350F while you prepare your batters. We'll prepare each dough separately.
In a large bowl, whisk together liquid ingredients until smooth. Sift in dry ingredients and using a spatula, mix until a dough forms. You can start to use your hands to work the dough as needed. Set your ball of dough to the side and prepare the next batter the same way.
If the doughs feel really soft, give it some time in the refrigerator to firm up a little bit before working.
First, roll out your vanilla dough on parchment paper to create a long, rectangular shape. Next, roll out your cinnamon filling dough and lay over top of the vanilla dough. Start to roll up the doughs, using the parchment paper to help lift the dough and roll forward, until one roll is formed. Make sure the roll is quite tight!
Slice the roll to create cookie shapes, about ½ inch thick, or thicker if you prefer a chewy cookie. Flatten out slightly to seal any air pockets and place on baking tray.
Bake at 350F for 8-10 minutes, or until edges are just browning. Remember the cookies will continue to bake once out of the oven, so don't be tempted to over bake them, especially if you like them soft.
Let cool before enjoying for at least 10-15 minutes.
Ice with coconut butter or other icing of choice if desired using a piping bag or spoon while warm.
