Follow these step-by-step instructions to create the perfect Frosted Lemon Shortbread Bites:

Making the Shortbread Bites:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
2. Cream the Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. This should take about 2-3 minutes using an electric mixer on medium speed.
3. Add the Lemon Zest and Vanilla: Mix in the lemon zest and vanilla extract until well incorporated.
4. Combine the Dry Ingredients: In a separate bowl, whisk together the all-purpose flour and salt. Gradually add the dry ingredients to the butter mixture, mixing until a soft dough forms.
5. Shape the Dough: On a lightly floured surface, roll out the dough to about ¼ inch thickness. Use a small cookie cutter to cut out bite-sized shapes, and place them on the prepared baking sheet.
6. Bake: Bake the shortbread bites in the preheated oven for 10-12 minutes, or until the edges are lightly golden. Remove from the oven and let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Preparing the Lemon Glaze:

7. Mix the Glaze Ingredients: In a small bowl, whisk together the powdered sugar, fresh lemon juice, and lemon zest until smooth. If the glaze is too thick, add a little milk to reach your desired consistency.
8. Frost the Shortbread Bites: Once the shortbread bites are completely cooled, drizzle or spread the lemon glaze over each bite. Allow the glaze to set for about 15 minutes before serving.
