These cookies are great for Valentine's day gifts for teachers, neighbors, or family members. These are a really fun kid's baking craft idea to do with your little ones.
In a small bowl, whisk the salt and flour together.
In a large bowl, beat the butter and sugar together at medium-high speed until pale and fluffy.
Beat in the egg and vanilla.
Add the flour mixture to the butter and sugar mixture and mix at low speed until just combined.
Form the dough into 3 equal disks and individually wrap and chill the disks until firm.
Chill in fridge for 2 hours.
Preheat oven to 350°.
Crush up your candies. It doesn't matter how small because it will all melt together during the baking process.
Roll out the dough to about 1/8 inch thick on a well-floured surface one disk at a time.
Don't forget to use a silicone baking mat, parchment paper, or waxed paper or it will be impossible to get the melted candy off of your baking sheet. If you don't use a cookie cutter for the cutout, try to smooth the edges or the color of the melted candies will bleed into any jagged edges.
Try to keep the crushed candy within the cutout borders if you want an absolutely pristine look, otherwise you'll end up with tiny sprinkles of color on your cookie or the color may overflow.
Bake at 350° for 10-12 minutes or until edges are golden.
