Mashed Idaho® Potato Coffee Ring with Cinnamon Drizzle

Tender dough made with potato, brown rice flour and almond meal, with a nice contrasting crunch from the cinnamon-sugar walnut filling, and addictive butter-toffee like shards that bake up around the edges from the filling that oozes out.


Dough Ingredients:

  • 1 1/3 cups whole milk, warmed to 110°F
  • 6 tablespoons unsalted butter
  • 5 teaspoons yeast
  • 1/2 cup granulated sugar
  • 1 1/3 cup Idahoan potato flakes
  • 1 1/3 cup brown rice flour
  • 2/3 cup finely ground almond flour (almond meal)
  • 2/3 cup tapioca starch
  • 1 teaspoon baking soda
  • 3 teaspoons xanthan gum
  • 5 teaspoons baking powder
  • 1 teaspoon salt
  • 2 large eggs plus 2 egg whites
  • 1/2 cup coconut oil, warmed to a liquid
  • 2 teaspoons vanilla
  • non-stick vegetable spray
  • parchment paper for rolling out the dough

Filling Ingredients:

  • 2/3 cup unsalted butter, melted and still hot
  • 1 cup brown sugar
  • 3 tablespoons cinnamon
  • 4 tablespoons potato starch
  • pinch of salt
  • 2/3 cup finely-chopped walnuts

Glaze Ingredients:

  • 1 cup confectioners sugar
  • 1/2 teaspoon vanilla
  • 1 tablespoon half-and-half (or a little more or less to make glaze to the consistency you prefer)


  1. Proof yeast: Combine warmed milk, butter, yeast and sugar in a large bowl. Set aside in a warm place to proof for 30 minutes until foamy.
  2. Make filling: Combine dry ingredients and then pour in the hot, melted butter, stirring until smooth.
  3. Make dough: Combine the dry ingredients for the dough in the work bowl of a stand mixer. Set aside.
  4. When the yeast mixture is foamy, add the egg coconut oil and vanilla to the yeast mixture. With the stand mixer running at a very low speed, pour the liquid ingredients into the dry-mixture in a steady stream. Increase speed to medium and beat for 5 minutes, stopping to scrape the bowl as needed. If making the coffee cake: Gather the dough into a soft ball and set in a large oiled bowl in a warm place to proof for 15 minutes. If making cinnamon rolls: Divide the dough into two portions and proof.
  5. Roll-Out Dough: Spread work surface with two, overlapped pieces of parchment paper. Spray with vegetable oil. If making the cake: Place dough-ball at the center. Gently flatten the ball to make a rectangle with your hands. Cover the dough with two more vegetable-spray-coated sheets of parchment (sprayed side down)
  6. Roll out until 1/2 inch thick. (be careful not to roll too thin.) Spread filling over the dough, leaving a 1-inch border along the far edge. Using the parchment paper to help, gently lift and roll the dough into a spiral. Slightly flatten this to make a five inch wide oblong coffee cake. Tuck ends under. Wrap and refrigerate for 1/2 hour. If making cinnamon rolls: do this process twice, using each portion of dough and rolling up into a "round" log rather than the flattened one used for the cake.
  7. Remove chilled cake OR cinnamon roll logs from refrigerator. If making cake, place entire loaf on parchment-lined half-sheet pan, seam-side down. If making cinnamon rolls, butter two cake pans. Slice each cinnamon-roll log into 12 rolls and place in each pan.
  8. Set aside to proof for 12 minutes.*
  9. While rolls OR cake are proofing, preheat oven to 350°F.
  10. Place rolls OR cake in center of oven and bake for 25 minutes until puffed and golden.
  11. Make glaze. Drizzle glaze over warm rolls.


Adding potato to sweet roll dough makes for a very tender crumb. This gluten-free cinnamon roll recipe has potato in the dough and potato starch in the cinnamon-sugar-butter filling.

*Note: You can make this ahead but completely steps 1-7 and then covering and refrigerating. When you're ready to proceed, bring back up to room temperature for 30 minutes and then bake.
