Combine flour, SPLENDA® Brown Sugar Blend and salt in a large bowl. Work butter and shortening into the flour with a pastry cutter or by pulsing in a food processor until a rough, crumbly texture. Add 3 tbsp (45 mL) of the water and mix or pulse to bring dough together, adding a little more water as needed. Shape dough into a disk and chill for an hour before rolling.
