Sift together flours, baking powder, and salt in a large bowl. Cut butter into small chunks and then cut into flour with two knives or a pastry cutter, until the butter pieces are no larger than a pea. Form a well in the center. Beat together eggs and pour into well. Stir until it starts to come together, then add in jam and mix until it is incorporated. The dough should not be sticky.
Dump the dough out onto a flour-covered counter and knead just a bit to get the dough to stay together. Divide in half, then half again. Pat each section into a flat circle. Using a sharp knife or pizza cutter, slice each circle into 6 pieces.
Place scones 1 inch apart on a parchment lined baking sheet. Bake for 15 minutes or until golden brown.
