Preheat oven to 350 degrees F and line a large baking sheet with parchment paper.

In the bowl of an electric mixer fitted with the paddle attachment, add the butter and 1 cup of granulated sugar. Mix on medium until light and fluffy (approx. 3 minutes).

Add in the lemon juice and lemon zest and mix until incorporated.

Add the flour and mix on low until just incorporated.

In a separate shallow medium bowl, add ¼ cup granulated sugar.

Using a small cookie scoop, scoop out a tablespoon of cookie dough and roll it between the palm of your hands.

Roll the ball of dough in the granulated sugar and place it on the prepared pan.

Repeat this process with 11 more balls of cookie dough--1-inch balls, slightly smaller than the size of a golf ball, are ideal.

Using your thumb or the back of a teaspoon, press a circle into the center of the cookie.

Add approximately 1 teaspoon of jam to the center of each cookie.

Bake in the oven on your greased cookie sheet for 12-14 minutes or until the edges are slightly golden brown.

Allow cookies to cool slightly before transferring them to a wire rack to cool completely.

In a small bowl, add the powdered sugar, milk, and fresh lemon juice. Whisk until completely combined.

If the glaze is too thick, add a tiny more milk ¼ teaspoon at a time until you reach desired consistency.

Use a spoon, fork, or whisk and gently flick the glaze back and forth over the tops of the cooled cookies.

Allow the glaze to set completely before stirring.
