*If using unsalted butter then add ¼ teaspoon of salt.
Instructions
Pre-heat oven to 350° (180° celsius). Line cookie sheets with parchment paper.
In a medium bowl whisk together, flour and salt, set aside.
In a large bowl beat at medium speed, butter and sugar until light and fluffy, approximately 2 minutes, add the egg yolks and vanilla, beat until just combined. Stir in flour mixture with a wooden spoon or flat beaters until combined.
Roll dough into approximate 1 inch balls (2.5 cm). If dough is very soft refrigerate for 30 minutes.
Place egg whites in a small bowl and cocoa in another bowl. First roll balls in egg whites and then in cocoa, place on prepared cookie sheets about one inch apart. Gently make an indentation with your thumb or end of a wooden spoon in every ball. Bake for approximately 15 minutes, at the halfway point check to see if the centres have puffed up, if yes, then using the end of a wooden spoon gently indent again. Remove from the oven, cool for 2 minutes, place one unwrapped kiss of choice in the middle or let cool completely and fill with Chocolate Cream Spread or filling of choice. Enjoy!
Notes
The cookies should be stored in an airtight container and will keep at room temperature for up to 1 week.They can also be frozen in a freezer safe bag or container, place parchment paper between the layers so they don’t stick together. They will keep in the freezer for up to 3 months.The unbaked cookie balls can also be frozen for up to 3 months, freeze the balls first on a cookie sheet then move to a freezer safe container. They can be baked without thawing although they will take a bit longer to bake.
