1. Beat egg and buttermilk together and set aside.
2. In large mixing bowl, whisk the flours, sugar, baking powder and salt together. Add the butter and the peanut butter and using a pastry cutter, fork, or your fingers, cut it into the flour until you have a pebbly mixture the size of peas.
3. Pour the egg/buttermilk mixture into the flour/butter mixture and stir to combine with a rubber spatula. It should come together into a sturdy dough (add a bit more whole wheat flour, if necessary to bring it together).
4. Turn the dough out onto a floured surface and divide in half. Roll each portion out into a disc.
5. Place one of the discs on a parchment or silpat-lined baking sheet, then spread with the jam. You want it to cover the whole surface...I used 1/2 cup of jam, but you might need a little more or a little less depending on how thick your disc is rolled out.
6. Carefully transfer the other disc (I used a large flat spatula) to lay on top of the jam layer, then cut the disc into 8 triangular shaped pieces.
7. Place baking sheet with the prepared scones in the freezer overnight.
8. Take the sheetpan out of the freezer and preheat the oven to 350 degrees F. Separate the scones so they are a few inches apart and brush the tops with the egg wash. Sprinkle generously with organic sugar, then bake for 22-25 minutes, or until they are nicely browned on top.
