Idaho® Potato Holiday Cookies

Potatoes? In holiday cookies? You bet! The potatoes help keep the cookies soft and tender for several days at room temperature. Break out the sprinkles and frosting and recruit the kids to help decorate. 

Ingredients:

  1. Wash, peel, and cut the potato into 1" pieces.
  2. Place in a saucepan in lightly salted water, and bring to a boil. Reduce the heat to a simmer and cook for about 15 minutes or until potato pieces are easily pierced with a knife. Drain, cover, and return to low heat for 5 minutes to dry a bit.
  3. Preheat oven to 400°F and set a rack in the top and bottom thirds. Line your cookie sheets/baking pans with Silpat or parchment and set aside.
  4. Mash well with a masher and measure out 2/3 cup (6 oz) of mashed potato. Put in a bowl and save the rest of the potato for another purpose. I just make buttery mashed potatoes and eat them as a snack.
  5. Stir the milk (cold is fine) into the reserved mashed potatoes and set aside.
  6. Whisk the flour and baking powder together. Set aside.
  7. Cream together the butter, sugar, salt, lemon zest and vanilla extract until light and fluffy, scraping the bowl as necessary.
  8. Add the egg and beat until combined, scraping the bowl as necessary.
  9. Mix in the mashed potato/milk mixture until combined, scraping the bowl as necessary.
  10. Add the flour/baking powder mixture all at once and mix on low until combined. Scrape the bowl. The texture of your batter should be like very thick cake batter. It should flow a little bit but not be runny.
  11. Portion cookies using a 2 oz scoop for large cookies or a 1 oz scoop for smaller cookies. Leave a good 2 1/2" between the cookies, especially if using 6 oz of milk. You may need to bake a 3rd round, so don't try to crowd the pans or the cookies will run into each other and end up with some flatter sides, and we want nice, round cookies.
  12. Bake large cookies for about 16 minutes and smaller cookies for about 12 minutes. Rotate the pans and swap racks halfway through baking. The cookies are done when they are firm and barely starting to color on the tops and are a warm, deep golden brown on the bottoms.
  13. Let cool on the sheets for a couple of minutes, and then carefully transfer them to racks to cool completely.

For the Glaze:

  • 3 cups confectioner's sugar (powdered sugar)
  • 2 tablespoons light corn syrup
  • 1 tablespoon lemon juice from the lemon you zested earlier
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon vanilla extract (use clear vanilla for the truest color)
  • 3-5 teaspoons water, as needed
  • Red and green food color

For the Decorations:

  • Homemade or store-bought decorator's icing in white, green, red or silver

Directions:

  1. Wash, peel, and cut the potato into 1" pieces.
  2. Place in a saucepan in lightly salted water, and bring to a boil. Reduce the heat to a simmer and cook for about 15 minutes or until potato pieces are easily pierced with a knife. Drain, cover, and return to low heat for 5 minutes to dry a bit.

For the Glaze:

  1. Whisk together the confectioner's sugar, corn syrup, lemon juice, salt, vanilla and a tablespoon of water until smooth. Add water a bit at a time until you have a spreadable consistency that will smooth out upon sitting – a very thick glaze.
  2. Divide the glaze into 3 bowls. 
  3. Color 1 bowl of glaze with red color, one with green and keep the rest white.
  4. Using an offset spatula, spread half of all the cookies with the white glaze and let set up about 5 minutes.
  5. Spread the other half of all the cookies with red or green glaze.
  6. Allow the glaze to harden for at least an hour, and then decorate as desired with decorator's icing.

Notes:

To keep the cookies as consistent in size as possible, use cookie scoops of the right size. For large cookies, use a 2 oz (¼ cup scoop). For smaller cookies, use a 1 oz (2 tablespoon) scoop.
