Mulberry Thumbprint Jam Cookies: The Little Gems Your Cookie Jar Has Been Begging For

Description

Okay, so you’ve got mulberries (lucky you!) and you’re wondering what to do with them besides eat them straight off the tree like a woodland creature? Enter these ridiculously adorable thumbprint cookies. Picture this: buttery, melt-in-your-mouth shortbread cookies with a jammy mulberry center that’s like a little jewel of summer. They’re fancy enough for your book club but easy enough for a Tuesday night baking session when you’re stress-eating your way through Netflix.

These cookies are basically the lovechild of sophistication and comfort food. The mulberry jam is tart-sweet perfection, and the cookie base is so tender it practically dissolves on your tongue. Plus, making the little thumbprint indentations is weirdly therapeutic — like adult Play-Doh but with way better results.


Ingredients

Scale

For the Mulberry Jam:

  • 2 cups fresh mulberries (or frozen, thawed)
  • 1/3 cup granulated sugar
  • 1 tbsp lemon juice
  • 1 tsp vanilla extract
  • Pinch of salt

For the Cookie Dough:

  • 2 cups all-purpose flour (or almond flour for gluten-free)
  • 1/2 tsp salt
  • 1 cup unsalted butter, room temperature (don’t skip this step)
  • 2/3 cup powdered sugar
  • 1 large egg yolk
  • 1 tsp vanilla extract
  • 1/2 tsp almond extract (trust me on this)

For Assembly:

  • The mulberry jam you just made
  • A little extra powdered sugar for dusting (optional but pretty)

Instructions

Step 1: Make That Jam

Toss mulberries, sugar, lemon juice, and salt in a small saucepan.

Cook over medium heat, stirring occasionally, until berries break down and mixture thickens (about 10-12 minutes).

Stir in vanilla. Let it cool completely — seriously, don’t rush this part.

Step 2: Cookie Dough Magic

Whisk flour and salt in a bowl. Set aside.

In a large bowl, cream butter and powdered sugar until light and fluffy (about 3-4 minutes with an electric mixer).

Beat in egg yolk, vanilla, and almond extract.

Gradually mix in flour mixture until just combined. Don’t overmix — we want tender cookies, not hockey pucks.

Step 3: Shape and Chill

Roll dough into 1-inch balls and place on parchment-lined baking sheets.

Here’s the fun part: use your thumb to make indentations in each ball. Go about halfway down — you want a nice little well for the jam.

Pop the whole tray in the fridge for 30 minutes. This prevents spreading and keeps those thumbprints nice and defined.

Step 4: Bake Time

Preheat oven to 350°F while cookies chill.

Bake for 12-15 minutes until edges are just barely golden. Don’t overbake — they’ll keep cooking on the hot pan.

Step 5: Jam It Up

While cookies are still warm, gently re-press the thumbprints if they puffed up during baking.

Spoon about 1/2 teaspoon of cooled mulberry jam into each indentation.

Let cookies cool completely on the pan before moving them.

Notes

Jam consistency: Your jam should coat a spoon but not be too thick. If it’s too runny, cook it a bit longer. Too thick? Add a splash of water.

Room temperature butter: This isn’t optional. Cold butter won’t cream properly and your cookies will be dense.

Don’t skip the chill: Cold dough holds its shape better and gives you those perfect thumbprint wells.

Storage hack: Store in an airtight container for up to a week. The jam actually gets better after a day or two.
