Apple Skull Galette

0 Beat the maple syrup and butter on medium-high until mixed. Add the egg and vanilla. Beat until smooth. Add the flours and mix. 
1 Wrap the dough in parchment paper and place in the refrigerator for at least 30 minutes. 
2 Meanwhile, make the filling. In a large bowl, mix the sugar, arrowroot flour, lemon juice, and cinnamon. 
8 Cut the apples in half and remove the cores. Use a melon baller to scoop out two eye sockets in each apple half. Use a small knife to carefully cut a nose and mouth into each apple half to create the skull faces.
3 Preheat the oven to 350F. 
4 On a large piece of parchment paper, roll the dough out into a circle with a 12-inch diameter. 
5 Place the apple skulls on the dough, leaving about 1 inch of the edge. 
6 Fold the outer crust into the apples. Brush the crust with egg white, then sprinkle on sugar. 
7 Bake for 35 to 40 minutes or until the curst is slightly browned. Enjoy warm as is or with a scoop of ice cream.
