Ultimate Valentine Day’s Cookies! These cookies are a little bit complicated, but they will totally be worth all the effort when you slice the cookie roll to reveal a pretty rainbow heart. These painstakingly resplendent confections are a gift that defeats any attempt at romance (roses or chocolates ).

3/4 cup unsalted butter, softened
1 1/4 cup confectioner’s sugar
1 tsp vanilla
pinch of salt
3 large egg yolks, at room temperature
