"Create a pecan thumbprint cookie recipe with a caramel glaze and no heavy cream. Use a buttery cookie base with chopped pecans folded into the dough. The filling should be a simple caramel glaze made without heavy cream, using ingredients like butter, brown sugar, milk, powdered sugar, vanilla, and salt. Include imperial measurements, clear steps, bake temperature and time, yield, and tips for keeping the thumbprints intact."
