Switch on your oven to 350°F (175°C) and lightly coat a mini muffin tray with grease. Cream together the butter and sugar until it’s fluffy. Beat in the egg and vanilla. Mix the salt, flour, and baking powder in a separate dish. Gradually fold the dry mix into the wet mixture until a soft dough develops. Shape the dough into 1-inch balls and pop them into the muffin tin, pressing in the center with your thumb or the back of a small spoon.

Bake them for 10-12 minutes or until the sides just turn golden. Take them out of the oven, and if the centers need more shape, press them in again carefully using a spoon. Let them cool completely in the tin before you attempt to remove them.

Pop the sugar, eggs, lemon juice, lemon zest, and flour in a little pot and mix well over medium heat. Stir non-stop until it thickens and starts to coat the back of your spoon—this takes roughly 5-7 minutes. Take it off the heat and allow it to cool a bit.

Once the cookie cups are cooled, scoop the lemon mixture into the middle of each one until they’re filled to the brim.

Dust the tops lightly with powdered sugar. For extra flair, throw on some lemon zest or curls if you like. Serve immediately or put them in the fridge for a cool snack later.
