Why Youโ€™ll Love This Recipe:

Simple three-bowl cookie recipe

You only need basic mixing bowls and a hand mixer to make these delicious homemade cookies. You absolutely don’t need a fancy stand mixer.  You’ll end up with with fewer dirty dishes, and less time cleaning up. 

Super easy to customize with all kinds of amazing flavors

This thumbprint cookie recipe is pretty easy to make your own. You get to mix and match your favorite jams or preserves depending on personal preference and what you have on hand. I find myself almost always reaching for raspberry jam, but blueberry, apricot, or strawberry jam also work beautifully. 

You can even incorporate a variety of add-ins, like chopped nuts, orange or lemon zest, or even warm spices like cinnamon, nutmeg, or cardamom. For something a little different, you could try rolling the cookie dough balls in chopped walnuts instead of granulated sugar. There’s a bunch of ways to modify or build on the original recipe and make it even better. 

A soft, buttery, and slightly crisp way to use sourdough discard

I’m always on the hunt for new recipes that will use my leftover starter, and this delicious recipe is a sure bet. But it sure isn’t the only one. There are times I turn to my cornbread recipe, this lemon cake recipe, and a few other family favorites. 

Ingredients You’ll Need

* For full ingredient list and precise measurements, scroll to the bottom of this post to find the recipe card*

  • Unsalted butter -For these easy cookies, the butter needs to be at room temperature. If it is too cold, the ingredient won’t mix properly and if it is melted, the cookies won’t keep their shape. If you use salted butter, reduce the salt by 1 gram (1/4 teaspoon). 
  • White Sugar-Adding sweetness and makes the baked cookies a little crispy on the edges. Also promotes a smooth dough texture by helping the butter to cream just right. 
  • Brown Sugar-I use lightly brown sugar, as it helps add moisture and the usual subtle caramel flavor brown sugar is known for. 
  • Egg Yolk – Adding the egg white will make this dough too runny and the cookies will lose their shape while baking. Instead, just add the egg yolk.
  • Sourdough Starter – For sweet recipes like these cookies, sourdough discard that is 1-2 days old works best! You can use active sourdough starter, just be sure to use the same amount in grams.
  • Flour – All-purpose flour is perfect for this recipe.
  • Cornstarch – Makes the cookies light and tender, while also helping them keep their circular shape.

How to Make Sourdough Thumbprint Cookies

Wet Ingredients

  1. Add softened butter to a large bowl. Beat with an electric mixer on medium speed until creamy, about 30 seconds.ย 
  2. โ€‹To the butter, add the white sugar and tightly packed light brown sugar. Cream on medium speed for an additional 30 seconds until combined.ย 
  3. Then, add the egg yolk, sourdough starter discard, and vanilla extract and mix until combined.
Softened butter, sugar, leftover starter, vanilla and egg yolk creamed in a large bow.

Dry Ingredients

In a separate bowl, whisk together the flour, cornstarch, and salt.ย 

Mix

With your mixer on low speed, gradually add the dry ingredients to the butter mixture. Occasionally you will need to stop and scrape the sides of the bowl. The cookie dough will look dry and crumbly, but keep mixing through this, everything will come together.ย

Shape

With a cookie scoop or hand, scoop about 1 Tablespoon worth of cookie dough and roll it into a tight and smooth ball. It is important that there are no air pockets in the dough, otherwise, this can lead to cracks in the exterior of the cookie dough.

*In-between batches, I like to store the cookie dough or shaped cookie dough balls in the fridge so the butter doesn’t melt.

Rolling the cookie dough ball in granulated sugar

If desired, roll the balls of dough in granulated sugar. This gives the cookies a sweet and crisp outer layer. It also helps to prevent your teaspoon or thumb from sticking to the dough when you are making your indents.ย 

Filling

  1. With a small teaspoon or your thumb, make a small indent in the center of each cookie. If the cookie dough cracks, reroll and try again. Repeat with the rest of the cookie dough.ย 
using a small spoon to ladle strawberry jam into the indent
  1. With a small spoon, ladle your favorite jam or preserves into the indent of your cookie.

*A neater option would be to add your jam to a piping bag. You choose!

Bake

Line the baking sheet with parchment paper. 

Then add your sourdough thumbprint cookies to your prepared cookie sheet, spacing them about 1-2 inches apart. 

Bake your cookies in a 350-degree f oven for 15-17 minutes, or until the top is set and the edges of the cookies are a light golden brown. 

Remove the cookies from the oven and place them on a wire rack to cool. 

How to Store

Sourdough Thumbprint Cookies will keep in an airtight container for up to a week. I love to showcase mine in my favorite cookie jar. 

These cookies also freeze for up to 3 months. Or shape and freeze the cookie dough with the jam in the center in an air-tight container or ziploc bag. Bake from frozen for fresh cookies at a moment’s notice. 

FAQs

What is another name for thumbprint cookies?

Another name for thumbprint cookies is Hallongrotta, ย the name of a common Swedish cookie. The name translates to mean “raspberry caves” in Swedish.ย 

Why are my sourdough thumbprint cookies dry?ย 

It is important to not over bake these cookies! I typically will only bake them for 15-17 minutes, or when the tops have set and the bottoms are just turning golden brown.ย 

My sourdough thumbprint cookies are spread out! What do I do?

A Sourdough Thumbprint Cookie that spreads out can happen for a few reasons. Maybe there just wasn’t enough flour, the dough needed a little more chill time, or the butter was too melty when you were shaping the dough.ย For the best results, I highly recommend using a kitchen scale.

Whatever the cause, you might still be able to save the cookies. When the cookies are still warm, use two spoons gently to push the edges of the cookie back toward the center. This little trick might not always be a perfect fix, but it’s worth a try!ย 

Can the thumbprint cookie recipe work for other kinds of cookies?

Sure thing! If you crave lemon curd cookies, bake the cookies, let them cool, and then spoon in lemon curd. What if you want to bake sourdough cranberry thumbprint cookies? Just spoon in cranberry sauce into the middle just before oven time. And for blossom cookies, simply press a chocolate kiss into the middle instead of jam post-baking. As for turtle cookies, have caramel in the center and then top with a pecan. This cookie dough is an amazing base that’s super easy to work with, however you like to bake cookies.

Ingredients

  • 1/3 cup (75g) white sugar
  • 1/3 cup (75g) light brown sugar, tightly packed
  • 1 egg yolk, room temperature

  • 1/2 teaspoon (4g) salt
  • 2/3 cup of your favorite jam or preserve

10. With a small spoon, ladle your favorite jam or preserves into the indent of your cookie.

When you pull the jam/preserves from the jar, it will be a little firm, so I like to scoop it into a small bowl and heat it in the microwave for 5-10 seconds. This softens the fruit filling and makes it easier to spoon onto your cookies. 

*A neater option would be to add your jam to a piping bag. You choose!

Bake

11. Line the baking sheet with parchment paper. 

12. Then add your sourdough thumbprint cookies to your prepared cookie sheet, spacing them about 1-2 inches apart.

14. Remove the cookies from the oven and place them on a wire rack to cool.

Notes

  • For the most precise baking, I recommend using a kitchen scale. It's a really cheap investment, but it will ensure accuracy!
  • Make sure the butter is at room temperature. Using melted butter will make the cookies spread while baking.
  • It is important to not overbake these cookies! I typically will only bake them for 15-17 minutes, or when the jam thumbprints have set and the bottoms are just turning golden brown.ย 
  • If your cookies spread while baking, do this. When the cookies are still warm, slide the outside of the spoons on the edge of the cookie, pushing them toward the middle.
  • Store in an airtight container for 1 week or in the freezer for 3 months.
