In a mixer with a paddle attachment, combine flour, salt, baking powder, sugar, lemon zest, butter and cream cheese. Mix until it resembles coarse crumbs.
Whisk the egg, egg yolk and vanilla extract together and add to the flour. Mix until all the dry ingredients are combined with the wet and dough forms a ball.
Divide the dough in half, flatten into a disk and wrap in plastic wrap. Chill for 30-45 minutes or overnight. If chilling overnight, let the dough rest at room temperature for 5-10 minutes before attempting to roll out.
Preheat the oven to 375.
Roll out the dough to about ¼" thickness on a sheet of parchment, sprinkled with some flour to prevent sticking.
Place a cup of strawberry filling in the center and fold in the edges and pinch to form a "bowl" to hold the filling.
Brush with egg wash and sprinkle with coarse sugar.
Bake 30-40 minutes until golden.
Serve immediately with vanilla ice cream or whipped cream.
Notes
For whole-grain I use 6 oz. (1.5 cups) soft white wheat and 2 oz. (.5 cups) rice or oat flour For Gluten-free use 4 oz. (1 cup) rice flour, .5 cup oat, and .5 cup sorghum flour. Also add 1 tsp Guar Gum to the dry ingredients and 1-2 tbsp water to the wet ingredients.
