Preheat the oven to 400℉. Line a large baking sheet with parchment paper.
Whisk the flour, baking powder, and sugar together in a large bowl. Cut in the cold butter using a pastry cutter until the pieces of butter are the size of peas. Stir in the mini chocolate chips.
Whisk together the cream, egg, and vanilla in a small bowl and add to the flour/butter mixture. Stir together until the dough just starts to come together. Turn the contents of the bowl onto a clean counter and knead the mixture until the dough just begins to come together. Do not over-mix!
Flatten the dough into 6 rounds about 2 ½ inches in diameter and 1 inch thick. Cut each round into 4 wedges using a pizza cutter or large knife and place them on the prepared baking sheet. Bake in the preheated oven for 14-17 minutes or until lightly golden brown.
Let the scones cool on their baking sheet before dipping in the glaze (recipe below). Enjoy!
To make the Glaze:
Whisk together the melted butter, powdered sugar, milk, and vanilla extract. Dip the scones upside down in the glaze and set them on a plate or a cooling rack. Sprinkle with additional mini chocolate chips, if desired.
