Creating Brown Sugar Pop Tart Cookies is easy and fun! Just follow these simple steps:

1. Prepare the Dough: In a large bowl, cream together the softened butter and brown sugar until light and fluffy.
2. Add Egg and Vanilla: Beat in the egg and vanilla extract until well combined.
3. Mix Dry Ingredients: In another bowl, whisk together the flour, salt, and baking powder.
4. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until a dough forms.
5. Chill Dough: Wrap the dough in plastic wrap and refrigerate for at least 30 minutes. This helps the dough firm up.
6. Preheat Oven: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
7. Roll Out Dough: After chilling, roll out the dough on a floured surface to about ½ inch thick.
8. Cut Shapes: Use a cookie cutter or knife to cut the dough into squares or rectangles.
9. Fill Cookies: Place half of the cut shapes on the baking sheets. Add a teaspoon of fruit preserves to the center of each shape.
10. Cover with Top Shapes: Take the remaining cut shapes and place them over the ones with filling. Press the edges to seal well.
11. Bake: Bake in the preheated oven for 12-15 minutes or until the edges are lightly golden.
12. Cool: Allow the cookies to cool completely on the baking sheet.
13. Make Icing: In a small bowl, mix the powdered sugar and milk until smooth. Adjust the consistency by adding more milk if needed.
14. Decorate: Drizzle or spread the icing over the cooled cookies for that signature Pop-Tart look.

With these steps, you will have a batch of delightful Brown Sugar Pop Tart Cookies ready for enjoyment!
