To make the dough, combine the flours, baking powder, salt, and cinnamon in a medium bowl. In a large bowl, whisk together the oil and sugar. Add the eggs, whisking after each, and then whisk in the vanilla and lemon zest. Using a wooden spoon or spatula, mix in the dry ingredients to form a dough. Divide the dough in half and pat out into discs. Wrap in plastic wrap and refrigerate for 2 hours or up to a day or two.
Preheat the oven to 350ºf and line two baking sheets with parchment paper and set them aside.
On a floured surface, working with one dough disc at a time, roll it out until it is 1/8” thick, adding more flour as needed to prevent sticking. Cut out 3” circles, re-rolling scraps as needed. Place a 1 teaspoon schmear of cream cheese in the center (I find it easiest to smoosh it on with my fingers) and top with a heaping teaspoon of jam, allowing a 1/2” border around the edges. Brush the border with egg wash and fold the edges up to form a triangle shape, pinching the corners firmly to seal. Sprinkle the jam with a tiny pinch of flaky salt. An optional fun step for added crunchiness: brush the outside edges with egg wash and cover with coarse sanding sugar or turbinado sugar, if using. Place on the baking sheets, 1” apart and bake until the bottoms are lightly browned, begin checking for doneness at 13 minutes. Let cool slightly and enjoy! If you didn’t go the sanding sugar route, you can dust with powdered sugar or just leave them plain!
