For the oatmeal base and topping:
- ¾ cup butter, melted (1 ½ sticks; I use unsalted butter, but salted butter will work just as well): The butter forms the rich base for the Carmelita dough. If you prefer a lighter option, you can substitute half of the butter with applesauce or Greek yogurt, although this will slightly alter the texture and flavor. However, I highly recommend using butter for that classic, rich taste.
- ¾ cup light brown sugar, packed: Brown sugar adds moisture and a deep, caramelized flavor that complements the sweetness of the caramel and chocolate. If you prefer a less sweet alternative, you can substitute with coconut sugar or maple sugar, though the flavor may differ slightly.
- 1 tablespoon vanilla extract: Vanilla is a key flavor in the oatmeal crust and adds depth to the overall flavor of the Carmelitas. Make sure to use pure vanilla extract for the best taste. For a twist, you can experiment with flavored extracts such as almond or hazelnut.
- 1 cup all-purpose flour: All-purpose flour provides structure to the oatmeal base. If you’re looking for a gluten-free option, you can swap the all-purpose flour with a gluten-free flour blend.
- 1 cup whole-rolled old-fashioned oats (ensure they’re not instant or quick-cooking oats): Oats are the heart of the Carmelita base, providing chewiness and texture. Use old-fashioned rolled oats to ensure the right consistency. Instant oats will work in a pinch, but they won’t have the same chewy texture.
- 1 teaspoon baking soda: Baking soda helps the dough rise and gives the Carmelitas a light texture. Make sure it’s fresh for the best results.
- ½ teaspoon salt (adjust to taste): Salt enhances the flavor of the caramel and chocolate. If you’re using salted butter, you may want to reduce the added salt to ¼ teaspoon.
For the caramel layer:
- 35 caramel squares, unwrapped (I recommend using Werther’s Originals Soft Caramels, which are slightly bigger than cellophane-wrapped caramels. If you use the smaller wrapped caramels, add a couple more): Caramel squares are the easiest way to make the caramel filling, and Werther’s Originals are a great choice due to their smooth texture. You can also use pre-made caramel sauce if you’re short on time, though homemade caramel will yield the best flavor.
- ½ cup heavy cream: Heavy cream is what makes the caramel smooth and velvety. If you prefer a lighter option, you can substitute with coconut cream, but the flavor and texture will vary slightly.
For the chocolate layer:
- 1 cup semi-sweet chocolate chips or chunks (you can use a combination of both, like I did, for added texture and flavor): The chocolate layer adds a rich, melty layer to the bars. Semi-sweet chocolate is ideal, but you can also experiment with milk or dark chocolate, depending on your preferences. Chopped chocolate bars or chocolate chunks also work well and can add a more rustic look to the bars.
