Dough:

• Preheat your oven to 350 degrees F and grease a 9 inch pie dish or casserole dish.
• In a large bowl, whisk together your tapioca flour, almond flour, xanthan gum, baking powder, and salt.
• In a separate bowl combine your melted butter, sugar, eggs, apple cider vinegar, and vanilla extract.
• Add your wet ingredients to your dry mixture and mix until combined, your dough will be sticky.
• Add 2 tbs warm water to your dough and mix well. Let your dough rest for 5 minutes to firm up. While your dough rests mix together all of your filling ingredients and set aside.
• On a piece of parchment paper, spread about 1 tbs of tapioca flour so it covers about 8X12 inches. Take your dough and place it on your working surface, cover with parchment paper and roll your dough with a rolling pin into a 8X12 even rectangle.
• Combine all of your filling ingredients in a bowl, except the oreos, mix until smooth.
• Spread your filling mixture evenly over your dough, leaving at least a 1/2 inch around the edges. Evenly sprinkle your crushed oreos over your filling.
• Using the short side (the 8 inch side) carefully roll your dough rectangle into a log. Cut into nine equal pieces. Place your rolls in your greased dish and bake for 25-30 minutes.
• Combine your topping ingredients and whisk until smooth. Once your cinnamon rolls slightly cool, spread your topping on top and enjoy!
