Thumbprints are one of my all time favorite cookies and they always remind me of Christmas. My next door neighbor (and best friend growing up) always had jam thumbprints at her house during the holidays and it was the only time of year I got to enjoy these little jam filled cookies!
Every month, Hannah from Make It Dough and I collaborate on a fun recipe using sourdough. With the holidays coming, we knew we had to make a cookie recipe! So, this spiced thumbprint cookie recipe uses up sourdough discard to reduce food waste and give you delicious thumbprint cookies that are all dressed up for the holidays!

Ingredients

- Butter: I use salted butter, always. But, if you prefer to use unsalted butter that's okay too. You may want to add 1/4 teaspoon to 1/2 teaspoon of salt to the recipe if you're using unsalted.
- Sourdough Discard: You can use your sourdough starter discard straight from the fridge. You do not need active sourdough starter.
- Spices: I use organic allspice and cloves for a simple cozy spice mix that makes these cookies just festive enough.
- Turbinado Sugar: I roll the cookie dough in organic turbinado sugar which gives them a sparkly look and a perfect subtle crunch.
- Jam or Preserves: You can use any kind of jam or preserves for this recipe. This lightly spiced thumbprint cookie recipe goes well with so many flavors, so you can use your favorite. Homemade or store bought both work! I used Persimmon Apple Cider Jam and Organic Strawberry Jam With Fresh or Frozen Berries in these. But, raspberry jam, apricot jam, blueberry or your favorite jam also works!

Baker’s Tips
- Always weigh ingredients for the best results.
- I use my stand mixer for ease, but if you want to use a hand mixer, that's okay too.
- Make sure your butter is soft. I like to leave out at room temperature to soften naturally.
- If you don't have sourdough discard, you can still make this recipe. Just mix together 28 grams all purpose flour and 28 grams of water and use in its place. It won't have the same flavor, but it will still make a delicoius thumbprint cookie!
- If you don’t have turbinado sugar, you can skip that step. It’s not necessary but it gives these cookies a little sparkle and a subtle texture that I really love.
- You can use any jam or preserves flavor you like.
- You can make your own jam or use store bought, either is fine!
- High Altitude — Bake at 350°F 18 to 21 minutes, or until lightly browned on the bottom.
How to Make Sourdough Jam Thumbprint Cookies

- Preheat the oven to 350. Line 2 baking sheets with parchment paper. In the bowl of a stand mixer fitted with the paddle attachment, add the butter, cane sugar, and vanilla extract.

- Mix on low until combined, then speed the mixer up to speed 4 and mix for about 5 minutes until the butter has lightened in color and is fluffy.

- Add the sourdough discard.

- Next, add the dry ingredients: flour, allspice, and cloves. Mix together until combined into a smooth dough.

- Add the turbinado sugar to a small bowl. Using your hands, form the dough into 30 small balls and roll each dough ball in the turbinado sugar.

- Place the dough on the prepared parchment-lined baking sheet and press your thumb into the center to create an indention.

- Using a small spoon, fill the indent with jam.

- Bake for 19 to 22 minutes, or until lightly browned on the bottom. Let cool completely on the cookie sheets. (If you're baking at high altitude, be sure to check the Notes at the bottom of the recipe for high altitude baking instructions).

Yes, these are a great holiday cookies for cookie boxes because they are a great cookie to prep ahead of time and they don't need to be stored in an airtight container, they can just be left out. That makes them great for DIY Christmas Cookie Box.
