Preheat oven to 450°F (230°C). In a large bowl, stir together pancake mix, milk, and melted butter until a shaggy dough comes together, about 30 seconds.

Dust a counter with flour. Pat dough into a 1/2-inch rectangle, fold in half, pat again, and repeat twice more. Finish by patting to 3/4 inch thick. Cut with a floured 2-inch cutter, pressing straight down without twisting, and gather scraps to cut again. You should get 8 biscuits.

Place biscuits close together on an ungreased baking sheet. Bake 8 to 10 minutes until golden brown and baked through.

Cool on a rack for 1 minute, then serve warm, split open with butter or jam.
