Preheat oven to 350°F (175°C). Grease and flour a 9-inch cake pan.
In a large bowl, cream together the butter and sugar until light and fluffy.
Beat in the eggs one at a time, then stir in the lemon zest and lemon juice.
In a separate bowl, whisk together the gluten-free flour, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Beat until just combined.
Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely.
Prepare the glaze: In a small bowl, whisk together the powdered sugar and lemon juice until smooth. Add more lemon juice as needed to reach the desired consistency.
Drizzle the glaze over the cooled cake.
