Why do my thumbprint cookies crack when I press the well?

Cracks mean the dough is too cold or too dry. Let the scooped balls stand 5 minutes before pressing, press slowly with a floured wooden spoon handle, and pinch any small crack closed with your fingers. If cracks persist, the flour was likely packed; spoon and level it, or weigh 280 grams.

Why did my thumbprint cookies spread flat in the oven?

Spreading comes from warm butter. The dough should feel cool and matte when shaped; if it looks shiny, chill the shaped balls 15 minutes before filling. Also confirm the 45 minute dough chill happened; it is what sets the butter before the heat does.

How much jam goes in each thumbprint cookie?

Exactly 1/2 teaspoon per cookie. More than that bubbles over the edges and scorches on the pan, and much less leaves a dry, shallow center. A thick, seedless jam holds its shape best; thin preserves can be simmered 2 minutes to thicken before filling.

Can I freeze thumbprint cookie dough before baking?

Yes, and it is the best make-ahead route. Shape the balls, press the wells, and freeze solid on a tray before bagging for up to 3 months. Thaw overnight in the refrigerator, then fill with jam and bake as directed for glossy, fresh-tasting centers.

The wells puffed up and nearly closed while baking. How do I fix that?

It happens when the dough is slightly under-chilled. As soon as the tray leaves the oven, press each well once more with the spoon handle while the cookies are hot and soft. They set within minutes, and the fresh well takes the jam neatly if it drifted.

Instructions

Beat the butter and granulated sugar until pale and fluffy, 2 to 3 minutes.
Beat in the egg yolks one at a time, then the vanilla and almond extract, until smooth and glossy.
Add the flour and salt and mix on low just until a soft dough forms with no dry streaks.
Cover and chill the dough for 45 minutes, until firm enough to scoop cleanly.
Heat the oven to 350°F (175°C). Line two baking sheets with parchment paper.
Scoop 1 tablespoon balls, roll smooth, and set 2 inches apart on the sheets.
Press a deep well into each ball with your thumb or the floured handle of a wooden spoon. Pinch any cracks closed.
Fill each well with exactly 1/2 teaspoon of jam.
Bake 13 to 15 minutes, until the edges are barely golden and the jam shines. Keep the tops pale.
If a well puffed up, press it once more with the spoon handle while hot. Cool 5 minutes on the sheet, then move to a rack.
Dust lightly with powdered sugar if you like, keeping it off the jam.
