Thumbprint Cookies With Icing Recipe

Make Thumbprint Cookies With Icing Recipe: tender walnut cookies filled with silky buttercream. Easy, festive, and crowd-pleasing.

Ingredients

• 1 1/2 cups all purpose flour
• 1 tsp baking soda
• 1/4 tsp salt
• 3/4 cup butter, softened
• 1/2 cup light brown sugar
• 1 egg
• 1/2 tsp vanilla extract
• 1 cup walnuts, divided
• 1/4 cup butter, softened
• 2 tbsp milk of choice
• 2 cups powdered sugar
• A few drops red and/or green food coloring, optional

Instructions

Step 1: Preheat the oven and prep your pans

Preheat the oven to 350°F and line a baking sheet with a sheet of parchment or a silicone baking mat so everything slides off cleanly after baking. Getting the oven hot and the sheet prepped ahead of time keeps the cookies baking immediately when they go in, which helps preserve a tender crumb and even color.

Step 2: Pulse the walnuts

Place the walnuts in a food processor and pulse in short bursts for about 20 seconds until they are finely chopped but not pasty; you want small, irregular crumbs with some texture. If you don’t have a processor, tuck the nuts into a zip-top bag and crush them with a rolling pin, leaving a few larger bits for visual interest and crunch.

Step 3: Mix the dry ingredients

In a large mixing bowl whisk the all-purpose flour, baking soda, and salt until the powders are evenly distributed and light. This simple sifting-by-whisking keeps the rising agent dispersed so the cookies bake uniformly and you avoid pockets of baking soda in any single bite.

Step 4: Cream the butter and sugar

In a separate bowl beat the softened butter and light brown sugar until smooth and airy, then add the egg and vanilla and mix until fully incorporated. The creaming stage should look glossy and slightly voluminous — this is the tender, fluffy base that keeps the cookies soft.

Step 5: Bring the dough together

Fold the wet mixture into the dry ingredients and stir until the dough just comes together, a few dozen seconds of gentle folding should do it. If it seems too dry add a single tablespoon of milk and be patient — avoid overworking. When cohesive, the dough should be slightly tacky but firm enough to roll.

Step 6: Fold nuts and shape the cookies

Stir half of the crushed walnuts into the dough until evenly scattered. Roll the dough into uniform balls about one inch in diameter, then roll each ball through the remaining crushed walnuts so they’re evenly coated. Arrange the walnut-coated balls on the lined baking sheet about 2 inches apart so they have room to spread.

Step 7: Initial bake and press the thumbprint

Bake the cookies for 10 minutes until the edges are just set and the centers still slightly soft. Remove the pan, wait 1–2 minutes until the cookies are cool enough to touch but still warm, then gently press a thumb or the back of a measuring spoon into each center to make the classic well without pushing all the way through.

Step 8: Finish baking and cool

Return the sheet to the oven for another 3–5 minutes until the cookies are golden and set. Remove and transfer the cookies to a wire cooling rack to stop the residual heat from overbaking them. Let them cool fully so the fillings won’t melt when added.

Step 9: Make the buttercream

While the cookies cool, whisk softened butter and milk until smooth, then beat in the powdered sugar until the icing is thick, silky, and pipeable. Add a few drops of red or green food coloring if you want pastel holiday hues. Wait until the cookies have completely cooled before filling the wells so the icing holds shape.

Step 10: Fill and serve

Pipe or spoon the buttercream into each thumbprint cavity, filling to a glossy dome, and top each with a small dollop of jam or a caramelized nut for contrast. Let the icing set briefly, then arrange the cookies in a staggered pattern on a platter or rack for serving — they should look rustic, golden, and inviting.

Notes

• If dough is crumbly, add milk one tablespoon at a time until it holds together.
• For extra flavor, brown the butter before using and cool slightly.
• Freeze undecorated cookies and fill after thawing for best texture.
• Toast walnuts briefly for a deeper nutty flavor but watch them closely.
• Use a piping bag with a small round tip for neat buttercream centers.
