Carmelitas

Preheat oven to 350F. Line an 88-inch pan with aluminum foil and spray with cooking spray. Lining your pan is highly recommended for ease of cleanup due to the stickiness of the caramel; set pan aside. **I often use a 8x13 pan instead, I prefer more bars, not as thick.**

In a large microwave-safe mixing bowl, add the butter and heat on high power to melt, about 90 seconds.

Add the brown sugar, vanilla, and whisk until smooth.

Add the flour, oats, baking soda, optional pinch salt, and stir until combined. Mixture will be quite thick.

Add half of the mixture to the prepared pan (just eyeball it), and smooth it with spatula or the back of a spoon, to create an even, smooth, flat layer; set remainder aside.

Bake for 10 minutes. While it bakes, make the caramel sauce.

Combine caramels and cream in a medium saucepan, and heat over medium-low heat to melt, stirring nearly continuously, until mixture can be stirred smooth.

Optionally stir in 1/2 teaspoon salt, or to taste, for salted caramel sauce; set sauce aside.

After 10 minutes, remove pan from the oven and evenly sprinkle with the chocolate.

Slowly and evenly pour caramel sauce over the chocolate.

Evenly crumble reserved oatmeal-brown sugar mixture over the top.

Return pan to oven and bake for about 15 to 18 minutes (I baked 16 1/2), or until edges are lightly browned and center is bubbling slightly.

Allow bars to cool completely in the pan before slicing and serving, giving the molten caramel time to firm. This can take up to 4 hours, or overnight, at room temperature. You can also place pan in fridge with a sheet of foil over the top to prevent fridge smells. If you dont wait for bars to cool completely, theyll be a literal hot mess. Theyll taste fine (dont burn yourself), but they wont slice neatly with clean cuts. Bars will keep airtight at room temperature for up to 4 months.
