Carmelitas (Squares)

Pillsbury Bake-Off royalty from 1967, these caramelitas are the original ooey-gooey bar cookie that made caramel-and-chocolate-on-oats a permanent fixture of American baking. The construction is a layered build: half the oat crust on the bottom, par-baked, then chocolate chips, pecans, molten caramel poured over, and the rest of the crust crumbled on top.

The par-bake is what gives these bars their structure. Skipping it leaves the bottom soggy and the bars fall apart on the lift. Ten minutes in a 350°F (175°C) oven sets the base into something that can support the gooey middle without dissolving.

Melting caramels with evaporated milk (not regular milk or cream) is the canonical move here. The concentrated milk solids in evaporated milk thicken the caramel as it cools so it stays gooey but sliceable, instead of running out of every slice.

The two-hour fridge cool is mandatory. Try to slice these warm and you’ll have caramel disasters and crumbled bars; chilled, they cut clean and the caramel stays where you want it.

Pro Tips

• Crumble the top oat layer between your fingers so it falls in a relaxed scatter, not a packed lid. You want craggy texture and visible caramel peeking through.
• Toast the pecans in a dry skillet for 5 minutes before adding for deeper flavor.
• Line the pan with parchment with overhang for easy lift-out before slicing.
• Bring to room temperature before serving for the gooiest bite, or eat cold for a firmer chew.

Variations

• Use butterscotch chips instead of chocolate for a double caramel hit.
• Add a sprinkle of flaky sea salt before the second bake for salted caramel bars.
• Swap pecans for walnuts or skip nuts entirely for a kid-friendly version.
