Preheat oven to 375 degrees & line a baking sheet with parchment paper
In a large bowl, mix together the flour, baking powder, sugar, & salt
Add in the butter & using a pastry cutter or fork, break up the butter so it turns into a crumbly mixture
Gently stir in the diced strawberries, egg, vanilla & white chocolate chips
Gently stir in 1-2 tablespoons of half & half or cream at a time until the batter comes together, it should be a bit sticky, do not over mix
Scoop out heaping tablespoons of the batter onto the parchment paper lined baking sheet (an ice cream scoop was perfect for this)
Sprinkle the tops of the scones with the decorative sugar
Bake on the middle-upper rack for 15-20 minutes, depending on the size of the scones & depending on your oven
Serve warm
