Heat oven to 400F and set rack in the middle of the oven
Add Sunrise Flour Mill Drop Biscuit Mix to a large-size bowl.
Add sugar and mix to disperse
Make a well in the center of the mix and add milk, butter, and vanilla. Whisk with a fork for about 10 seconds to combine, ensuring all mix is incorporated. Do not over mix.
Cover the bowl and let the dough rest for 10-15 minutes
Line a baking sheet with parchment paper. Spoon up about a quarter cup of dough (larger than a golf ball, smaller than a tennis ball) and drop on the prepared baking sheet. Space the biscuits 2-3in apart
Bake until golden brown- about 14-16 minutes
Remove from oven and brush the tops with melted butter.
Transfer to a cooling rack and allow to cool at least 15 minutes
