Delightful Poppy Seed Thumbprint Cookies made with butter, sugar, egg yolks & flour, then topped with strawberry jam or lemon curd. Perfectly sweet cookies with bright fruity flavor baked with buttery crisp edges.
Prep: Preheat the oven to 375°F. Line two cookie sheets with parchment paper and set them aside.
Dough: In a large mixing bowl, cream the butter and sugar on medium-high speed with an electric mixer until light and fluffy. This should take about 2-3 minutes. Add in the egg yolks and the vanilla extract, mix again to combine.
Add the flour, poppy seeds, and salt. Mix until incorporated and the dough comes together into a ball. If desired, chill the dough in the refrigerator for 30 minutes (this is optional).
Shape: Form the dough into 1-inch-sized balls that are perfectly round and then place them onto the prepared baking sheets. Using the backside of a ½ tsp measuring spoon, press an indent into the center of the cookies to create a crater.
Bake: Place the cookie sheets into the preheated oven and bake for 8-9 minutes.
Fill: Remove the baking sheet from the oven and if the indents look shallow, press them in again. Then, fill each indentation with strawberry jam or lemon curd.
Continue to bake in the oven for an additional 2-3 minutes or until the jam has melted slightly and the edges of the cookies are lightly golden in color. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a cooling rack to cool completely. Dust lightly with powdered sugar. Serve and enjoy!
