These sweet mulberry cookies have become my favorite way to celebrate mulberry season Each cookie is buttery crumbly and filled with a burst of mulberry jam in the center making them the perfect treat with a hot cup of coffee or as a sweet gift to friends
I made these first during a plentiful mulberry harvest and now everyone expects them each spring The homemade jam brings such a special touch and the cookies are always gone in a flash
Ingredients
- Allpurpose flour: gives structure and softness I always choose unbleached for best flavor
- Baking powder: helps the cookies rise and gives them a gentle lift Check that yours is fresh by testing it in water
- Powdered sugar: makes the dough tender and keeps the crumbs soft I use a sifter for a smooth result
- Salted butter: adds richness and balances the sugar Use highquality butter for a truly meltinyourmouth bite
- Vanilla extract: infuses the dough with warmth and depth Pure vanilla always wins over imitation
- Mulberries: the star of the show fresh or frozen both work well Look for plump berries without any mold or bruises
- Sugar: to sweeten the mulberry jam I use less than classic jams to let the fruit shine
- Lemon juice and lemon seeds: for the jam brighten flavors and help naturally thicken the filling Choose juicy lemons and carefully seed them
StepbyStep Instructions
- Mix the Dough:
- Combine flour baking powder and powdered sugar in a large mixing bowl Whisk gently to evenly blend Melt the butter and let it cool slightly Before adding it to the dry mixture with vanilla stir until a smooth uniform dough forms Cover and chill in the refrigerator for half an hour This ensures the cookies keep their shape during baking
- Make the Mulberry Jam:
- Wash and dry your mulberries first Measure them then process briefly in a food processor to break up the fruit Move to a small pot and add half as much sugar by weight Stir in lemon juice and toss in a few lemon seeds Heat on mediumhigh until boiling then simmer until the juices reduce by half and the mixture thickens well Remove the lemon seeds before using
- Shape the Cookies:
- Preheat the oven to three hundred fifty degrees Fahrenheit and line a baking sheet with parchment Divide the dough into balls about one tablespoon each Press your thumb gently into the center to create a little nest for the jam Space the cookies apart on the baking sheet
- Fill the Centers:
- Spoon about one teaspoon of mulberry jam into each indentation Take care not to overfill so the jam does not spill out in the oven
- Bake and Cool:
- Bake for twelve to fifteen minutes or just until the edges are turning golden Let them rest on the sheet for a few minutes before transferring to a rack This helps them hold shape and cool properly

There is something magical about homemade mulberry jam It fills the house with a sweet perfumed aroma that takes me straight back to childhood jammaking days My daughter loves pressing her thumb into the dough and filling it with the glistening purple jam
Storage Tips
After cooling thoroughly store your mulberry cookies in an airtight container at room temperature for up to four days For longer storage they freeze well Place cooled cookies in layers separated by parchment and thaw at room temperature before serving
