In a large mixing bowl, beat the egg yolks with an electric mixer until thick
Add powdered sugar and heavy whipping cream, and beat until fully combined
Add brandy, vanilla extract, half of the flour, and sea salt, and mix until just combined
Gradually add in the rest of the flour until a thick dough, non-sticky dough forms. To avoid over-mixing the dough, finish combining by gently kneading with your hands
Wrap the dough in plastic wrap and chill in the refrigerator for 20 minutes
Divide the dough into 2 equal parts and place one part back in the fridge
Roll dough into a ⅛-inch slab and trim any uneven edges
Cut dough into 1 inch thick strips and then cut each strip in half diagonally
Make a 1-inch slit lengthwise in the middle of each strip of dough
Slip one end of dough through the slit and gently pull to create an angel wing
Repeat steps 7-10 with second part of dough
