Instructions
RASPBERRY LEMON THUMBPRINT COOKIES
Cookie Dough
Preheat the oven to 350 degrees F. Line 2 baking sheets with parchment paper or silicone baking mats.
In a small bowl, combine the jam and Chambord/Kirsch/Limoncello (optional). Stir to combine.
In a medium bowl, combine the flour (2¼ cup, 325grams),baking powder, and salt and whisk to blend.
Using an electric mixer, beat the butter (1 cup, 2 sticks, 226 grams) and granulated sugar (2/3 cup, 135 grams) in a large bowl until light and creamy, about 3-5 minutes. Beat in the egg yolks (2 egg yolks), lemon zest (1 tablespoon), lemon juice (1 tablespoon), and Vanilla Extract (1 teaspoon). At low speed, add the flour mixture in 2 additions and beat just until moist clumps form. Gather the dough together, cover, and chill for 30-60 minutes.
Fill Cookies and Bake
Measure the dough with a 1-inch cookie scoop and place it onto a plate. Then roll each dough into a ball and transfer the cookie balls to the prepared baking sheets, spacing them 1 inch apart. Use your floured index finger or 1/2 teaspoon measuring spoon, a lightly oiled wooden handle, or a silicone wine stopper to create depressions in the center of each ball. Fill each indentation with about 1/2 teaspoon of the jam mixture. Bake cookie until lightly golden, about 18 minutes.
Transfer the cookies to wire racks to cool completely.
Notes
Apricot – add ¼ teaspoon cinnamon to the flour, replace raspberry jam with apricot, and omit the lemon zest and lemon juice. Use milk in place of lemon juice.
Cranberry – omit the lemon zest and lemon juice; in place of both, use orange zest and freshly squeezed orange juice, and add ¼ teaspoon almond extract.
Nutella Mocha – omit the recipe's lemon zest and lemon juice. Dissolve 1 tablespoon espresso powder in 1 ½ tablespoon milk and use this in place of lemon juice in the recipe. Bake cookies and fill the “potholes" with Nutella or other hazelnut spread after they cool.
