Chocolate Shortbread Hearts
Makes 2 1/2-3 dozen cookies
1 stick (1/2 cup) cold butter, cut into small pieces
1/4 cup sugar
1 cup flour
2 tablespoons Dutch-processed cocoa
Sift flour and cocoa together into a bowl. Whisk sugar and flour together.
Cut in butter until it resembles flakes. Kneed with hands until gathered and pliable. Chill overnight or several hours.
Preheat oven to 350F. Roll 1/4” thick and cut with heart shapes. Sprinkle with chocolate sprinkles or chocolate shavings, if desired. Bake on ungreased cookie sheets about 12-15 minutes. Transfer to wire racks to cool.
Cool completely. Store in airtight container.
