Carmelitas are buttery oat bars filled with a layer of salted caramel and chocolate chips, baked twice for a set crust and gooey filling. The dough comes together in one bowl and the bars slice cleanly once fully cooled. A reliable, crowd-pleasing bar cookie that requires no special equipment.
Preheat the oven to 350°F. Spray your chosen pan and line it with parchment.
In the bowl of a stand mixer fitted with the paddle attachment, combine butter, brown sugar, vanilla, flour, oats, baking soda, and salt. Mix on low speed until a cohesive dough forms. Alternatively, melt the butter and mix by hand.
Press half the dough evenly into the bottom of a half sheet pan, making sure the thickness is uniform across the entire surface.
Bake for 10-15 minutes, until the base is light golden brown. A metal pan will be done closer to 8 minutes; a ceramic dish will take closer to
While the base is still warm, spread the caramel evenly over the surface, then sprinkle the chocolate chips over the caramel.
Crumble the remaining dough over the top in an even layer. Return to the oven and bake for approximately 8-12 minutes.
Cool completely before cutting. Lift the slab from the pan using the parchment and cut on a flat surface.

Notes
Yield: 16 bars, cut into even squares. Doneness Cue: The crumble topping should look set and lightly golden at the edges after the second bake. The caramel layer will still appear soft but will firm as it cools. Storage: Store in an airtight container at room temperature for up to three days or in the freezer for 2 months. Make Ahead: Bake and cool completely, then store as above. The bars slice more cleanly on day two once the caramel has fully set.
