Measure and take butter in a mixing bowl, add powdered sugar to it.
Whisk it well, I used my hand whisk, you can use electric mixer too. Whisk it until creamy and fluffy.
Now add vanilla essence and salt. Finally add in the flour.
Mix with a spatula to form a dough.
Now use your hands to roll into a ball, cling wrap it and refrigerate it.
I used only half of the dough for this cookie.
Take your cookie cutters, you need a bigger one and a smaller one like this.
Roll out the dough slightly thin.
Cut out using the cookie cutters.
Remove the smaller flower. Now arrange it in a baking tray with parchment paper. Take a stick or toothpick.
While you do this, preheat oven at 180 deg C for 10mins.
Prick holes a the top of each cookies, incase you want to hang these cookies for decoration. Slice the log.
Keep the baking temperature for 12 mins, bake the cookies for 9 mins.
Take your candies, crush each color separately and keep it ready.
Now fill the holes with crushed candies, bake for the remaining 3 mins until it bubbles up. Let it cool down for 10mins.
Carefully remove the cookies and cool down in wire rack.
