Preheat oven to 400 degrees and line your baking sheet with parchment paper.
In a bowl, add your flour, sugar, baking powder, and pinch of salt. Whisk all of these ingredients together until they're fully blended.
Cut your butter up into pieces and add it into the flour. I used my pastry blender to make sure the butter was fully incorporated into the flour.
In a measuring cup or a small bowl, add the heavy cream, egg, and vanilla extract. Whisk up this mixture too and add it to your flour.
On the side, coat about 1 ½ cups of fresh blueberries in 1tbs of flour
Add in the blueberries. Use a wooden spoon to mix this all together and form a ball with the dough. Really work it between your hands to make a ball then flatten it into a 8 inch disc.
Cut the dough into six pieces and top with sugar (sugar is optional) Bake for 22 minutes until the scones are golden brown.
Enjoy the scones nice and hot!

Notes
Make sure the gluten-free flour is 1:1 so you don't need to change the measurements!
