– Gradually add the dry ingredients to the wet mixture. Mix until the dough comes together.

3. Shape and Decorate:

– Decorate with colored sugar or sprinkles if desired.

4. Bake the Cookies:

– Place the cookies on a greased or parchment-lined baking sheet, leaving space between them.

– Bake for 8–10 minutes, or until the edges are slightly golden.

5. Cool and Serve:
