Heat oven to 375 and grease a small baking sheet. Mix all dry ingredients, then cut in butter until it is crumbly and incorporated.
Add fruit, mix through, and then stir in buttermilk. Put a little flour on a flat surface (it's small enough to use a dinner plate for this), and turn the bread out over the flour. Knead a few times until it's a cohesive ball.
Place onto greased baking sheet and form into a 6 inch round. Cut a deep (about 3/4 inch) deep "X" onto top of bread. Bake for 30-35 minutes.
