Carmelitas are the kind of dessert bar that disappear fast anytime I make them. They have a buttery oatmeal cookie crust and topping with a gooey caramel center loaded with melted chocolate chips. They’re soft, chewy, a little crispy around the edges, and completely irresistible.
Line a 9x13-inch baking pan with aluminum foil, leaving a couple inches of overhang on each side for easy removal later. Spray the foil with nonstick cooking spray.
In a large bowl, stir together the flour, oats, brown sugar, baking soda, and salt.
Add the melted butter and mix until everything is evenly combined.
Press half of the oat mixture into the bottom of the prepared pan.
Bake for 10 minutes, then remove the pan from the oven while keeping the oven on.
While the crust bakes, add the caramels, evaporated milk, and heavy cream to a saucepan over low heat. Stir frequently until the caramels are fully melted and smooth.
Sprinkle the chocolate chips evenly over the baked crust.
Pour the melted caramel mixture evenly over the chocolate chips.
Crumble the remaining oat mixture evenly over the top.
Return the pan to the oven and bake for an additional 15 minutes.
Let the bars cool completely in the pan before lifting them out with the foil and slicing into bars.
Notes
Let the bars cool completely before cutting. The caramel layer needs time to set or the bars will fall apart when sliced.
For cleaner cuts, chill the bars for 30–60 minutes before slicing.
Nonstick foil works especially well for this recipe and makes cleanup much easier.
You can substitute soft caramel bits for unwrapped caramels to save time.
These bars are rich, so smaller squares are usually perfect for serving.
Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for a slightly firmer texture.
Carmelitas freeze very well. Wrap tightly and freeze for up to 2 months.
