Preheat your oven to 375 degrees F.In a large bowl, mix together all the dry ingredients up to cinnamon.Add cold margarine or butter and using a pastry blender or a fork, cut the fat into the dry ingredients to make small crumbly pieces.In a separate bowl, add all the wet ingredients. Pour the wet into the dry mixture slowly and mix gently with a fork until it comes together (careful to not overmix).Lastly, add in the sliced apples lightly until combined.Depending on your climate, you may not need all the liquid, 1 Tbsp or 2 Tbsp might remain. The dough will be wet.Cover your counter with additional oat flour. Gather the dough into a ball and flatten it out a bit. If the dough is very sticky still, keep kneading in a bit of oat flour until it comes together into a ball.Flatten out the ball into a rectangle, and using a sharp knife, cut it into 8 triangles, similar to cutting a pizza (first cut a big cross, then each quarter in half). Place each triangle on a cookie sheet lined with parchment paper.Sprinkle each scone with a bit of cinnamon and palm sugar.Place in oven and bake at 375 degrees F for 12-14 minutes. They will remain light in color, but will be firm.NOTE: These definitely taste best warm. So the next day, lightly microwave each scone for 15-20 seconds. Cutting in half and toasting them in a toaster would also work.
