Yield: approximately 12 sandwich cookies


  • ½ cup softened butter (or palm shortening for dairy-free) 
  • 1 cup sugar 
  • 1 egg (or 1 Tablespoon of gelatin)
  • ½ teaspoon vanilla 
  • 2 Tablespoons melted butter (or palm shortening)
  • 1 ⅓ cups of Otto's Naturals - Cassava Flour
  • ¼ teaspoon baking soda 
  • ¼ teaspoon cream of tartar


  • ¼ c. granulated sugar, topping 
  • 1 batch of your favorite homemade frosting 
  • All-natural food colorings


  1. Preheat the oven to 375°F and line baking sheets with parchment paper. 
  2. In a large bowl combine softened butter (or shortening) and sugar using a hand mixer. 
  3. Add egg, vanilla and melted butter to the butter and sugar mixture and mix until smooth. 
  4. In a separate bowl add cassava flour, baking soda and cream of tartar and mix until combined. 
  5. Combine dry ingredients into wet ingredients and mix well. 
  6. Roll dough into tablespoon-sized balls and roll them in the granulated sugar topping. 
  7. Place them on the baking sheets and gently flatten each ball. Bake for 6-8 minutes. Let the cookies cool on the pans for 3-5 minutes before transferring to a cooling rack. Cool completely before assembling the sandwiches. 
  8. Pair the cookies into sets of two. Prepare your frosting and color it as desired using the natural food coloring. Place a tablespoon of the frosting between each pair of cookies to make the sandwiches.
