Preheat your oven to 350°F (175°C) and grease a mini muffin tin. In a large bowl, beat the softened butter and granulated sugar together until light and fluffy. Add the egg and vanilla extract, mixing well. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until a soft dough forms. Roll 1-inch balls of dough and press each into the prepared mini muffin tin, creating a well in the center with your thumb or a small spoon.

Bake for 10–12 minutes, or until the edges are lightly golden. Remove from the oven and use a small spoon to gently reshape the wells, if needed. Let the cookie cups cool completely in the tin before removing.

In a small saucepan, whisk together the sugar, eggs, lemon juice, lemon zest, and flour over medium heat. Cook, stirring constantly, until the mixture thickens and coats the back of a spoon, about 5–7 minutes. Remove from heat and let cool slightly.
