Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a medium-sized bowl, whisk together the all-purpose flour, baking powder, and salt.

In a large mixing bowl, cream the softened unsalted butter and granulated sugar together until light and fluffy, about 2-3 minutes.

Add the egg and 1 teaspoon of vanilla extract to the butter mixture and mix until combined.

Gradually add the flour mixture to the wet mixture, mixing until just combined. Add pink food coloring if desired.

In a separate bowl, combine softened cream cheese, powdered sugar, and ½ teaspoon vanilla extract. Beat until smooth and creamy.

Scoop a tablespoon of cookie dough, flatten slightly, and place a small dollop of strawberry jam in the center.

Top with another tablespoon of cookie dough, seal the edges, and space on the baking sheet.

Bake for 10-12 minutes, until edges are set but the centers are still soft.

Allow cookies to cool on a wire rack. Prepare the glaze by mixing powdered sugar with a few drops of milk until smooth.

Drizzle the glaze over cooled cookies and sprinkle with sparkling sugar.
