Lemon Bar Cookie Cups: A Delightful Twist on a Classic Treat

Step 1: Make the Cookie Cups
Preheat your oven to 350°F (175°C). Grease a mini muffin tin or line it with paper liners.
In a large mixing bowl, cream together the butter and sugar until light and fluffy (about 2-3 minutes).
Add the egg and vanilla extract, mixing until combined.
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 the dough into 1-inch balls and press each ball into the muffin tin, forming a cup shape. Use your fingers or the back of a small spoon to create an indentation in the center of each cup.
Step 2: Bake the Cookie Cups
Bake the cookie cups for 10-12 minutes, or until the edges are golden.
Remove from the oven and, while still warm, gently press down the centers of each cup to reinforce the indentation. Let them cool completely in the pan before removing.
Step 3: Prepare the Lemon Filling
In a medium saucepan, whisk together the lemon juice, lemon zest, sugar, eggs, and flour.
Cook over medium heat, stirring constantly, until the mixture thickens (about 5-7 minutes). Do not let it boil.
Remove from heat and let the lemon filling cool slightly.
Step 4: Assemble the Lemon Bar Cookie Cups
Spoon the lemon filling into the cooled cookie cups, filling each one to the top.
Let the filled cups set in the refrigerator for at least 1 hour.
