This is my version of a “swig cookie” made for Christmas! Picture a soft, sour cream sour cookie full of peppermint bark chunks and a sour cream frosting. You’ll have to taste them to believe how good they are!

These thick, chewy cookies with slightly crispy edges are dotted with delicious candy cane pieces and topped with thick, chilled frosting.

You can skip the rolling pin and cookie cutter with these easy sugar cookies. Just flatten the gluten-free peppermint cookies dough with a glass cup to get perfectly imperfect, edges and then pop them in the oven.

Ingredients You’ll Need

Here are some notes on the key ingredients in these gluten-free peppermint cookies!

  • Gluten-free flour: It’s important to use high-quality gluten-free flour blends with xanthan gum for this gluten-free peppermint cookie recipe. I tested this recipe with King Arthur Gluten-Free Measure-for-Measure Flour.
  • Combination of oil/sour cream: These two ingredients give the cookies an amazing texture. They’re moist, rich and almost creamy in the middle. Be sure to use full-fat sour cream.
  • Andes peppermint crunch: You want to use the RED Andes peppermint crunch variety for these cookies, not the green. You can use the Andes Peppermint Crunch Baking Chips that come in a bag, or use the Andes Peppermint Crunch Thins and chop them up until you have about 1 cup.

How to Make Gluten-Free Peppermint Cookies

Make the Wet Ingredients: In the bowl of a stand mixer (or in a large bowl with an electric hand mixer), add the butter and mix on medium speed for 2-3 minutes, until light and fluffy.

Add the wet ingredients, starting by mixing the oil for another 1-2 minutes. Add the sour cream, egg and granulated sugar, vanilla extract and peppermint extract and mix on medium-low speed until well combined.

Add the Dry Ingredients: Add the baking powder, salt and ⅓ of the flour. Mix until well combined. With the mixer running on low, slowly add the rest of the flour and mix until evenly combined. Mix in the Andes Peppermint Crunch Chips.

Shape the Cookies: Use a cookie scoop to make ¼ cup-sized portions and roll the cookie dough into balls. Place the gluten-free peppermint cookies several inches apart on the prepared cookie sheet – I do 6 gluten-free peppermint cookies per baking sheet.

Add about 1/2 cup granulated sugar to a shallow dish or bowl. Lightly spray the bottom of a ¼ or ⅓ cup measuring cup (or small glass) with cooking spray and dip the bottom of the measuring cup into the sugar.

Press cookie dough into an even thickness dipping the bottom of the glass into the sugar between each press (no need to spray it again with cooking spray after the first time). The edges of the gluten-free peppermint cookies will ruffle out in an uneven way (imperfect is what you want!) They should be about 1/2-inch thick.

Bake/Frost the Cookies: Bake for 6-8 minutes. DO NOT OVERBAKE! These gluten-free peppermint cookies should not turn golden. You want them to be slightly underbaked from a normal sugar cookie so they’re soft and creamy when chilled.

Let the gluten-free peppermint cookies cool almost completely on the baking sheet before transferring to a wire cooling rack.

Frost the gluten-free peppermint cookies. For best results chill for at least 1 hour (or up to 2 days) before serving. Cookies are best served chilled right out of the fridge!

Storage Instructions

Store these cookies in an airtight container in the fridge for up to five days.

Recipe Tips

  • DO NOT OVERBAKE these cookies! These gluten-free peppermint cookies should not turn golden brown at all, otherwise they will lose moisture in the fridge and turn out dry and crumbly. You want them to be slightly underbaked so they’re soft and creamy when chilled. 
  • Use RED Andes peppermint crunch. Don’t use the green Andes mints for these gluten-free peppermint cookies — red is what you want. You can use the Andes Peppermint Crunch Baking Chips that come in a bag, or chop up Andes Peppermint Crunch Thins until you have one cup.
  • Spread out your cookies. These are generously sized gluten-free peppermint cookies that will spread a bit as they bake, so be sure to give them plenty of room on the baking sheet. I like to do six per baking sheet.
  • Dip the glass in sugar. Don’t forget to dip the glass in sugar before you press out the gluten-free peppermint cookies dough balls. The layer of sugar adds great texture and sweetness!
  • Serve chilled cookies. For best results, you need to serve these gluten-free peppermint cookies chilled! Although I don’t recommend serving them at room temperature, they would of course still be delicious.

  • 1/2 cup (110g) vegetable oil
  • 1 cup (240g) sour cream, full fat
  • 1 large egg
  • 1 ½ (300g) cups granulated sugar, plus more for rolling
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon peppermint extract
  • 1 teaspoon baking powder
  • 1 teaspoon salt
  • 3 3/4 (560g) cups gluten-free measure-for-measure flour (add up to 1/4 cup more if dough is too sticky)
  • 1 cup Andes Peppermint Crunch Baking Chips or Andes Peppermint Crunch Thins, chopped

For the Frosting:

  • 6 tablespoons (84g) butter, softened
  • 1/3 cup (80g) sour cream
  • 4 cups (450g) powdered sugar
  • 1/2 teaspoon peppermint extract
  • ½ teaspoon vanilla extract
  • pinch of salt
  • 1 tiny drop red food coloring

Instructions 

Make the Cookies

  • Preheat the oven to 350F. Line 2 large baking sheets with parchment paper or silicone baking mats.
  • In the bowl of a stand mixer (or in a large bowl with an electric hand mixer), add the butter and mix on medium speed for 2-3 minutes, until light and fluffy.
  • Add the oil and mix for another 1-2 minutes.
  • Add the sour cream, egg and granulated sugar, vanilla extract and peppermint extract and mix on medium-low speed until well combined.
  • Add the baking powder, salt and ⅓ of the gluten-free flour. Mix until well combined. With the mixer running on low, slowly add the rest of the gluten-free flour and mix until evenly combined. (Check the dough texture here: Depending on your flour brand you may want to add up to 1/4 cup flour if the dough is too sticky.) Mix in the Andes Peppermint Crunch.

Scoop the Cookies

  • Scoop the dough into about ¼ cup-sized portions and roll into balls. Place several inches apart on the prepared baking sheets – I do 6 per baking sheet.
  • Add about 1/2 cup granulated sugar to a shallow dish or bowl. Lightly spray the bottom of a ¼ or ⅓ cup measuring cup (or small glass) with cooking spray and dip the bottom of the measuring cup into the sugar.
  • Press each cookie into an even thickness dipping the bottom of the glass into the sugar between each press (no need to spray it again with cooking spray after the first time). The edges of the cookie will ruffle out in an uneven way (imperfect is what you want!) They should be about 1/2-inch thick.

Bake/Frost the Cookies

  • Bake for 6-8 minutes. DO NOT OVERBAKE! The cookies should not turn golden. You want them to be slightly underbaked from a normal sugar cookie so they’re soft and creamy when chilled.
  • Let the cookies cool almost completely on the baking sheet before transferring to a wire rack.
  • FROSTING: Using a hand mixer, mix together the butter, sour cream, powdered sugar, salt, peppermint extract, vanilla extra and 1 drop of red food coloring. Mix in a tablespoon or so of milk (or the liquid from the sour cream!) to get the frosting consistency you want. (I usually add 1-2 tablespoons.)
  • Frost the cookies. For best results chill for at least 1 hour (or up to 2 days) before serving. Cookies are best served chilled right out of the fridge! Enjoy 🙂

    I made these for Christmas and they were a crowd favorite!! I was thinking about making them for a Galentine’s party and wondering if you had any suggestions for a more vday theme??

  2. 5 stars
    This recipe is absolutely incredible. I made the peppermint ones first and then wanted to see if I could use the base recipe to make different flavors and it worked so wonderfully. I’ve never gotten so many complements on a batch of cookies ever!

    I also love that you used a 1:1 flour so there weren’t any weird conversions that needed to happen.

  3. I made these completely dairy free, and they were incredible! I used kite hill sour cream and added crushed peppermint and the enjoy life mini choc chips inside the cookie instead of the Andes. I wanted to bring them to a family get together and didn’t have a container but a neighbor had a crumble cookie box so that’s what I used. I had to convince my family they were homemade (and GF & DF) and not actually from crumble. Thanks for a fun new recipe!

    1. This is so helpful! Thanks for commenting with what you did to make these dairy-free as it will help others. So glad you enjoyed them!

    These cookies are delicious and we enjoyed them frosted at room temperature. Do they have to be refrigerated? I used to make non-GF sour cream sugar cookies there were not required to be refrigerated.
