Simple Gluten-Free Thumbprint Cookies

I never thought I’d be able to make thumbprint cookies after going gluten-free. You know that sad feeling when you assume your favorite treats are off the table forever? Yeah, I had that for a while.

But here’s the thing—gluten-free thumbprint cookies are actually easier to make than the regular kind. The dough comes together fast, and you don’t have to worry about overworking it like you do with wheat flour. Plus, that little indent you press with your thumb? It’s the fun part that makes these cookies feel special without requiring any fancy baking skills.

The best part is filling those little wells with jam and maybe drizzling some white chocolate on top. My kids always fight over who gets to do the thumbprint part, which tells you how simple this recipe really is.

What Kind of Gluten Free Flour Should I Use?

For thumbprint cookies, you’ll want to use a good quality gluten free all-purpose flour blend that’s designed for baking. Brands like Bob’s Red Mill 1-to-1, King Arthur Measure for Measure, or Cup4Cup all work really well and will give you the best texture. Make sure your blend already contains xanthan gum – if it does, skip adding the extra ¼ teaspoon called for in the recipe to avoid a gummy texture. Avoid using single-grain flours like almond flour or coconut flour on their own, as they won’t give you the right structure for these cookies.

Options for Substitutions

These cookies are pretty adaptable, so here are some swaps you can make:

• Gluten free flour blend: Stick with a good quality gluten free all-purpose blend for best results – this isn’t something you want to substitute with regular flour if you need these to be gluten free. I recommend blends like Bob’s Red Mill 1-to-1 or King Arthur Measure for Measure.
• Xanthan gum: Check your flour blend label first – many already include xanthan gum. If yours doesn’t and you don’t have any on hand, you can use ¼ teaspoon of guar gum instead.
• Butter: For dairy-free cookies, use vegan butter or coconut oil (measured solid). The texture might be slightly different, but they’ll still taste great.
• Almond extract: If you’re not a fan of almond flavor or have allergies, just use an extra ½ teaspoon of vanilla extract instead.
• Jam: Any flavor works here – raspberry, strawberry, apricot, or even lemon curd. You can also fill these with Nutella, peanut butter, or chocolate ganache if you want something different.
• White chocolate chips: These are totally optional for drizzling. You can use dark chocolate, milk chocolate, or skip the drizzle altogether.

Watch Out for These Mistakes While Baking

The biggest mistake with thumbprint cookies is making the indentation too shallow, which causes the jam to spill over the edges during baking – press your thumb down firmly to create a deep well that can hold at least a teaspoon of filling.

Another common error is adding the jam before baking, but it’s actually better to bake the cookies for about 8 minutes first, then press the centers again and add the jam before finishing, which prevents burning and keeps the fruit filling bright.

Since gluten-free dough can be crumbly, make sure your butter is properly softened (not melted) and consider chilling the dough for 15-20 minutes if it feels too soft to work with.

Finally, don’t skip letting the cookies cool completely on the baking sheet before moving them, as gluten-free cookies are more delicate when warm and can break apart easily.

What to Serve With Gluten Free Thumbprint Cookies?

These thumbprint cookies are perfect for serving at holiday parties, cookie exchanges, or just keeping around for an afternoon treat with coffee or tea. I love setting out a platter with a mix of different jam flavors – raspberry, apricot, and strawberry all look beautiful together and give everyone options. They’re also great alongside other cookies like chocolate chip or sugar cookies if you’re putting together a dessert spread. For a cozy evening, serve them with hot cocoa, a latte, or even a glass of cold milk for dunking.

Storage Instructions

Store: These thumbprint cookies stay fresh in an airtight container at room temperature for about 5 days. Just make sure the jam filling is completely set before stacking them, or layer them with parchment paper to keep them from sticking together.

Freeze: You can freeze these cookies for up to 3 months, either baked or as dough. If freezing baked cookies, let them cool completely and store in a freezer-safe container with parchment between layers. For unbaked dough, shape the cookies and make the thumbprints, then freeze on a baking sheet before transferring to a bag. Add the jam after baking.

Thaw: Frozen baked cookies can sit at room temperature for about 30 minutes before serving. If you froze the dough, you can bake them straight from the freezer, just add a minute or two to the baking time.

Ingredients

For the cookies:

• 1 egg
• 1/2 cup unsalted butter (I use Kerrygold, softened to room temperature)
• 1/4 tsp almond extract
• 1/2 tsp kosher salt
• 1 egg yolk
• 1.5 cups gluten-free flour blend (I use King Arthur Baking Company)
• 3/4 cup granulated sugar
• 1/4 tsp xanthan gum (if not already in your flour blend)
• 1 tsp vanilla extract (pure vanilla preferred for best flavor)

For the filling:

• 1/2 cup jam (any flavor, seedless or with seeds based on preference)

For the white chocolate drizzle (optional):

• 1/2 tsp vegetable shortening (helps thin the chocolate for easy drizzling)
• 1/2 cup white chocolate chips (optional but recommended for extra richness)

Step 1: Prepare Mise en Place and Preheat Oven

• 1/2 cup unsalted butter, softened to room temperature
• 1 egg
• 1 egg yolk

Start by preheating your oven to 350°F so it reaches the proper temperature by the time your dough is ready.

While the oven heats, gather all ingredients and measure them out—this is especially important with gluten-free baking since precision matters more.

Soften your butter to room temperature (it should be soft enough to leave a slight indentation when pressed but not melting or greasy), and separate your egg yolk from the white, setting the yolk aside for the egg wash later.

Step 2: Mix Wet and Dry Ingredients Separately

• 1.5 cups gluten-free flour blend
• 1/4 tsp xanthan gum
• 1/2 tsp kosher salt
• 1 egg
• 1 tsp vanilla extract
• 1/4 tsp almond extract

In one bowl, whisk together your gluten-free flour blend, xanthan gum (if your blend doesn’t contain it), and kosher salt to evenly distribute these dry ingredients and prevent clumping in the final dough.

In a separate bowl, whisk together the whole egg, vanilla extract, and almond extract—this creates a homogeneous wet mixture that will incorporate smoothly into the butter and sugar.

Step 3: Cream Butter and Sugar, Then Build the Dough

• 1/2 cup unsalted butter
• 3/4 cup granulated sugar
• wet ingredient mixture from Step 2
• dry ingredient mixture from Step 2

Beat the softened butter and granulated sugar together for 2-3 minutes until light and fluffy—this creaming process incorporates air and creates a tender cookie texture.

Gradually add the wet ingredient mixture from Step 2 while mixing on medium speed, scraping down the bowl as needed to ensure everything combines evenly.

Finally, add the dry ingredient mixture from Step 2 and mix on low speed just until the dough comes together; I prefer to use a spatula at the end to hand-mix slightly to avoid overdeveloping gluten and to ensure all dry pockets are incorporated without making the dough tough.

Step 4: Chill Dough and Shape Cookies

• dough from Step 3

Refrigerate your dough for 10 minutes to make it firmer and easier to work with—this prevents the dough from sticking to your hands and helps the cookies hold their shape during baking.

While the dough chills, prepare your baking sheets with parchment paper and set them nearby.

After chilling, roll the dough into 1-inch balls and place them about 1 inch apart on your prepared baking sheets.

Step 5: Add Thumbprints and Jam Filling

• 1/2 cup jam

Working with one ball at a time, use your thumb or the back of a small measuring spoon to press a gentle indent into the center of each dough ball, creating a small well without pressing all the way through to the bottom.

Spoon about 1/2 teaspoon of jam into each thumbprint—I recommend using a small measuring spoon or piping bag for consistent filling amounts.

Don’t overfill, as jam can spread during baking.

Step 6: Bake Cookies Until Golden

• prepared cookies from Step 5

Place the filled cookie sheets into your preheated 350°F oven and bake for 8-10 minutes, until the edges are just turning light golden brown but the centers still look slightly underdone.

The cookies will continue to cook slightly on the hot pan after removal from the oven.

Let them cool on the baking sheet for 2-3 minutes to firm up slightly, then transfer them to a cooling rack to cool completely before adding the chocolate drizzle.

Step 7: Melt White Chocolate and Finish Cookies

• 1/2 cup white chocolate chips
• 1/2 tsp vegetable shortening
• cooled cookies from Step 6

Once cookies have cooled completely, combine your white chocolate chips and vegetable shortening in a microwave-safe bowl.

Microwave in 30-second intervals, stirring between each interval, until fully melted and smooth—the shortening helps thin the chocolate slightly for easier drizzling and creates a silky texture.

Let the chocolate cool for about 5 minutes so it’s warm but not piping hot, then drizzle it over each cooled cookie using a fork or small spoon.

Allow the chocolate to set at room temperature for about 15-20 minutes before serving.
