These Argentine thumbprint cookies with jam are a delightful treat with a tender, buttery base and a dollop of sweet, slightly tart quince jam. Perfect with a cup of tea or coffee, they’re simple to make yet wonderfully nostalgic—a taste of Argentina in every bite.

Instructions
Dry ingredients
Mix all dry ingredients in a bowl.
2 cup all-purpose flour, 1 teaspoon baking powder
Wet ingredients
In another bowl, beat butter and powdered sugar using a handheld mixer for a few minutes until pale. Scrape the sides of the bowl as you go.
⅔ cup unsalted butter, 1 cup powdered sugar
Add the remaining wet ingredients and mix well.
1 large egg, 1 teaspoon vanilla extract, zest of 1 lemon
Add dry ingredients to the wet ingredients. Combine with a spatula and don't overmix. The dough will be sticky. Wrap the dough in cling film, flatten it, and chill in the fridge for 1 hour.
Filling
Add the paste to a small pot with water and cook over medium heat until a thick mixture forms. Break it apart as you go. Cool completely before using. We like to put it into a piping bag to fill the cookies more easily!
Assemble
Grease a baking tray with butter. Preheat the oven to 355°F (180°C.
Roll the dough into approximately ¾-inch balls with your hands and place them on the tray, spacing them 2 inches apart.
Flour your thumb and press it onto the center, or press the back of a measuring spoon into the center, and pipe a bit of the quince jam onto each. Flatten the jam's peaks with a wet finger.
Bake
Bake for 10 minutes on the middle rack until the bottom is golden brown. Cool on a rack, enjoy!
Notes
Softened butter. Soft butter creams better with the sugar, creating that light, fluffy texture we want.
Don't skip the chilling. It helps the cookies hold their shape during baking. No chilling means flat, spread-out cookies.
Even thumbprints. Use the back of a measuring spoon instead of your thumb.
Don't overfill. Regular jams are runnier than quince jam, so avoid overfilling the cookies, as they may overflow during baking.
Don't overbake. Look for golden brown bottoms. They might seem a bit soft when you take them out, but they firm up as they cool.
Avoid dough balls breaking when pressed. This happens when the dough is chilled for more than 1 hour, making it too hard. No worries, just warm it a bit by rolling the balls longer in your hands.
