Ingredients
Method
- Cream the butter and sugar until light and fluffy.
- Mix in the egg yolks and vanilla extract.
- Add the flour and salt and mix until just combined.
- Roll into 1-inch balls, press a thumbprint into each, and chill 15 minutes.
- Fill each indent with jam and bake at 350°F (175°C) for 12-14 minutes.
- Cool completely on the pan before serving.
Notes
- Use a thick jam, not a thin, runny one — thin jam is more likely to bubble over the edge while baking.
- Roll the dough balls smooth before pressing the indent to avoid cracking.
- Let the cookies cool completely before moving them, or the jam centers can crack the base.
