I bake them in a preheated 350°F (175°C) oven for 10-12 minutes. They come out looking puffed and set. This is the crucial moment: I immediately take the back of my measuring spoon and gently re-press the indentations, which have puffed up during baking. This ensures a perfect little cup for the jam. Then, and only then, do I let them cool on the sheet for 5 minutes before transferring to a wire rack. Once completely cool, I fill each warm indent with about ½ teaspoon of cherry jam. Filling them while still hot makes the jam melt and run everywhere—I learned that the hard way!
Pro Tips for Best Results
The temperature of your dough is everything for clean indents. I tested this three different ways: with room temp dough (too sticky), chilled dough (too hard to press), and dough that had rested for 15 minutes in the fridge. Trust me, that 15-minute fridge rest works better. It firms up the butter just enough so your thumbprint holds its shape without the dough sticking to your hands or tool.
When making the thumbprint, don’t be shy. Press deep enough that you’re about halfway through the dough ball. If you just make a shallow dent, it will disappear during baking. I use a gentle, twisting motion with the end of my measuring spoon to create a smooth, defined well. This little step of care ensures you get a good pool of jam in every cookie.
For a stunning presentation, I lightly dust the completely cooled and jam-filled cookies with a snowfall of powdered sugar. I do this right before serving. The white powder against the dark chocolate cookie and red jam is absolutely beautiful and adds a hint of extra sweetness. I’ve tried dusting before filling, and it just makes a mess. This order is key.
Common Mistakes to Avoid
My biggest first-time mistake was not re-pressing the indents right out of the oven. I was so careful making them before baking, only to watch them puff up into nearly smooth cookies in the oven. I tried to fill them anyway, and the jam just slid right off. Don’t do what I did! Have that spoon ready the second the tray comes out of the oven for a quick, firm re-press.(See the next page below to continue…)
