Preheat the oven to 350 degrees. Line a baking sheet with parchment paper.
Place the flour, sugar, salt, baking powder & baking soda in a large bowl and whisk together.
Make a well in the center of the dry ingredients. Place the egg, buttermilk, and melted butter in well and whisk together with a fork. Stir all of the ingredients together with the fork, then use your hands to continue mixing it into a dough. Once the mixture has come together, shape into a ball and place on the prepared baking sheet.
Pat the dough down a bit so that it the round is about 2" tall. Score the top of the round with a very sharp knife.
Bake in the preheated oven for 35-40 minutes, or until golden brown on top and cooked through.
Remove from the oven and let cool for 20 minutes.
Cut into wedges and serve with butter and jam.
