1/4 cup large-flake, old-fashioned oats
1/4 cup brown sugar
1 Tbsp flour
1 Tbsp butter melted
2 cups all purpose flour
2 Tbsp white sugar
1 Tbsp baking powder
1 tsp salt (3/4 tsp if using salted butter)
1/4 cup butter cold and cut in to 8 pieces
3/4 cup + buttermilk * cold and well shaken
Milk or cream for brushing tops
2 medium firm, ripe peaches peeled and diced
1 Tbsp flour
1/4 tsp cinnamon
1 cup icing/confectioners sugar
1 Tbsp + milk
Preheat oven to 425F. Line a baking sheet with parchment paper. Set aside.
Prepare topping mixture by combining all ingredients and stirring until moistened. Set aside. Peel and dice peaches and set aside.
In a medium bowl, whisk together well the flour, sugar, baking powder and salt. Add cold butter chunks to flour mixture. Using your fingertips, rub the butter in to the flour mixture until you have coarse crumbs with butter pieces no larger than a pea. Add about 2/3 of the cold buttermilk and using a fork, stir in to mixture until flour. Add more buttermilk, AS NEEDED, until the flour is just evenly moistened (but not wet).
Turn dough out on to floured surface. Gather the dough in to a mound and fold it over on to itself 2 or 3 times, until dough is one moist piece. Form in to a ball. Using a floured hand, press dough down until you have an even 1/2-inch thick piece of dough. Scatter diced peaches over 1/2 of the dough. Dust flour and cinnamon over-top of peaches. Fold the other 1/2 of the dough over the 1/2 with the peaches and press down lightly.
Using a 2-inch cutter, cut rounds from the dough and place on to parchment lined baking sheet, allowing several inches between each biscuit. Take scraps of dough and re-form in to a 1-inch thick piece and cut more. You should get about 6 biscuits. Brush tops of biscuits with a bit of milk or cream. Divide prepared topping mixture evenly on top of biscuits. Sweep away any that falls on the parchment (so it doesn’t burn).
Bake in preheated 425F. oven for 15-17 minutes or until lightly golden and just cooked through. Remove from oven, then remove biscuits from baking sheet on to a cooling rack. Allow to cool slightly, to enjoy warm or cool completely and store in an airtight container.
If you’d like to add the sweet glaze, combine the icing sugar and milk until you have a just pourable consistency. You may need to add more milk. Place a baking sheet under your cooling rack to catch the drips and pour your glaze over-top of the biscuits.
**Make your own buttermilk by adding 2 tsp vinegar or lemon juice to a 3/4 cup milk and allow to stand 5 minutes.
