In a large bowl, beat softened butter with granulated sugar and brown sugar until light and fluffy, about 2–3 minutes.

Add egg and vanilla extract to the butter mixture. Beat until fully blended.

Gradually mix the dry ingredients into the wet mixture until just combined. Avoid overmixing.
06 -
Scoop tablespoon-sized portions of dough and roll into balls. Arrange them 5 cm apart on the prepared baking sheets.

Flatten each dough ball slightly with your palm or the bottom of a glass. Bake for 10–12 minutes, until the edges are set and centers look slightly soft.

Let cookies cool on baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
09 -
While cookies cool, melt white chocolate in a microwave-safe bowl using 20-second bursts, stirring between each heating, until smooth.
10 -
Transfer melted white chocolate to a piping bag or small zip-top bag with a snipped corner. Pipe three concentric circles on each cookie, then use a toothpick to drag lines from the center outward, creating a spiderweb pattern. Repeat for all cookies and allow chocolate to set before serving.
