Mulberry Jam Thumbprint Cookies

These Mulberry Jam Thumbprint Cookies are buttery, delicate little treats with a burst of sweet-tart mulberry jam at their center. They’re simple, nostalgic, and just a little bit fancy—perfect for summer gatherings, teatime, or gifting in a pretty tin.

The soft, shortbread-like dough is easy to shape and holds the jewel-toned jam beautifully. Use store-bought or homemade mulberry jam (or sub in any berry jam you like). These cookies are as lovely to look at as they are to eat.

1. Yield, Time & Tools

  • Yield: 24 cookies
  • Prep Time: 15 minutes (plus chilling time)
  • Cook Time: 12–14 minutes
  • Tools Needed: Baking sheet, parchment paper, mixing bowls, hand or stand mixer (optional), teaspoon or thumb

2. Ingredients

For the Cookies:

  • 1 cup unsalted butter, softened
  • ½ cup granulated sugar
  • 1 egg yolk
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • ¼ teaspoon salt

For the Filling:

  • ½ cup mulberry jam (or any berry jam)

3. Preparation Steps

A. Make the Dough

In a large bowl, cream together butter and sugar until light and fluffy. Beat in egg yolk and vanilla. Mix in flour and salt until a soft dough forms. Chill for 30–60 minutes.

B. Shape the Cookies

Preheat oven to 350°F. Line a baking sheet with parchment paper. Roll dough into 1-inch balls and place 2 inches apart. Use your thumb or a teaspoon to gently press an indent into the center of each.

C. Fill & Bake

Fill each indent with ½ teaspoon mulberry jam. Bake for 12–14 minutes, or until edges are just golden. Cool on pan for 5 minutes, then transfer to a wire rack.

4. Tips & Variations

  • Use almond extract for a nutty twist.
  • Dust cooled cookies with powdered sugar for extra charm.
  • Try with peach, apricot, or cherry jam too.
  • Add a pinch of lemon zest to the dough for brightness.

5. Troubleshooting FAQ

Why did my cookies spread too much?
Make sure to chill the dough and use cool baking sheets.

Can I use homemade jam?
Yes—just make sure it’s thick enough not to run.

Can I freeze the dough?
Absolutely—wrap tightly and freeze for up to 2 months.

How do I keep the jam from bubbling over?
Don’t overfill the centers and avoid very runny jams.

6. Serving Suggestions

  • Serve with iced tea, lemonade, or coffee.
  • Pair with a fruit and cheese board for an elegant dessert spread.
  • Gift in jars or tins lined with parchment.

7. Storage and Make-Ahead Instructions

Freezer Instructions: Freeze baked cookies or unbaked dough balls; fill with jam just before baking.

Make-Ahead Tips: Dough and shaped cookies can be chilled a day ahead.
