Preheat your oven to 350°F (175°C) and line your baking sheets with parchment paper.

In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.

Add the egg, lemon juice, and lemon zest, mixing until fully combined.

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add the dry ingredients to the butter mixture, mixing until a dough forms.

Using a cookie scoop or tablespoon, drop dollops of dough onto the prepared baking sheets, leaving space between each cookie.

Bake in the preheated oven for about 10-12 minutes, or until the edges are lightly golden.

Let the cookies cool for a few minutes before transferring them to a wire rack.

Once completely cooled, spread a layer of strawberry frosting on the bottom of one cookie and sandwich it with another cookie.

Repeat until all cookies are frosted and sandwiched together.

Arrange the cookies on a platter and enjoy at your next gathering!
