Before You Start
Thumbprints are shortbread with a job to do: hold jam. The dough is barely sweet so the filling can shine, and the double-press (once before baking, again halfway through) is the trick that keeps the wells deep instead of puffing shut. Any thick jam works, and a mixed tray looks like you tried much harder than you did.
Instructions
-
1
Beat the butter and sugar until pale and creamy, about 2 minutes. Beat in the yolks and vanilla.
-
2
Fold in the flour and salt until a soft dough forms. Chill it for 30 minutes so the cookies hold their shape.
-
3
Heat the oven to 175°C / 350°F and line two trays. Roll the dough into 24 balls, about a tablespoon each.
-
4
Press a deep well into each ball with your thumb or the end of a wooden spoon. Cracked edges just get pinched back together.
-
5
Bake for 7 minutes, re-press the wells (they will have puffed), then fill each with a small spoonful of jam and bake another 6 to 7 minutes until the edges are pale gold.
-
6
Cool on the tray for 10 minutes before moving. The jam is molten glass straight from the oven, so no early taste tests.
💡 Baker's tips
- Fill with jam halfway through the bake, not before. Jam that bakes the full time boils over and candies to the tray.
- Stir the jam smooth before spooning. A lumpy spoonful bakes into a lopsided well.
🔀 Make it your own
- Roll the balls in chopped nuts before pressing for the bakery version.
- Fill with lemon curd or chocolate hazelnut spread after baking instead, once the cookies are cool.
📦 Storing & freezing
Airtight at room temperature for 5 days, with paper between layers so the jam does not glue them together. The dough freezes for 2 months.
❓ Frequently asked
Why did my thumbprint cookies spread flat?
Warm dough, almost always. Chill for a full 30 minutes and re-press the wells at the halfway mark. Butter that was too soft at the creaming stage makes it worse.
What jam is best for thumbprint cookies?
A thick, high-fruit jam. Raspberry and apricot are classics because their acidity cuts the buttery dough. Runny jam boils over, so avoid anything pourable.
