Preheat the oven to 400℉ and line a large baking sheet with parchment paper.

In a large mixing bowl, whisk together the flour, baking powder, and pudding mix. Using a pastry cutter, cut in the butter until the pieces are about the size of peas. Stir in the chopped white chocolate and sprinkles.

In another small bowl, whisk together the milk, egg, and vanilla extract. Add to the flour/butter mixture and stir until the dough starts to come together.

Turn onto the counter and use your hands to gently knead the dough and form it into 3 disks each around 3 inches in diameter. Cut each disk into quarters and place on the prepared baking sheet, leaving room between each scone for them to cool.

Bake the scones in the preheated oven for 12-15 minutes or until lightly golden. Remove from the oven and top with additional white chocolate if desired. Let the scones cool on the baking sheet for at least 10 minutes before serving.
